In July 2003 and 2004 small groups of geologists of AGH — The University of Science and Technology in Kraków investigated recent Andahua volcanic formation of Southern Peru. It was identified first some 45 years ago but its extension is not definitely determined yet. Field work resulted in discovery of about 100 individual emission centres: apparent pyroclastic cones 50–300 metres high, and usually smaller lava domes and vents by controlled fractures. Morphology of the Andahua lava flows coalescing into composite lava fields as well as criteria for their stratigraphy and tectonic controls are given.

Opis:
The basaltic rocks of Sośnica Hill near Targowica (Fore-Sudetic Block) belong to the Cenozoic Central European Volcanic Province. The volcanic succession at Sośnica is over 40 m thick and comprises pyroclastic fall deposits (mainly tuff breccias), subvolcanic intrusions (plug, dykes and other intrusive sheets) and aa-type lavas. Field relationships and structural data enable a detailed reconstruction of the vent location, morphology and eruptive history of the original volcano. Initial Hawaiian to Strombolian-type explosive eruptions produced a pyroclastic cone. Subsequently subvolcanic intrusions and lavas were emplaced. The lavas were fed from the central vent of the volcano, breached the cone and flowed southwards. Later eruptions resumed at a new vent on the western slopes of themain cone. The final volcanic edifice-a breached Strombolian scoria cone with a lava flow and a parasitic cone-was 500-1000 m in diameter at the base and 90-180mhigh. The preserved SWsector of this volcano, where the pyroclastic deposits were protected from erosion by the surrounding plugs and lavas, corresponds to ca. 1/2 of the height and 1/8 of the volume of the original volcano. Compared with many other remnants of Cenozoic volcanic centres in Lower Silesia, this volcano is exceptionally well preserved and exposed.

W 2003, 2004 i 2006 roku grupa geologów z Akademii Górniczo-Hutniczej w Krakowie prowadziła badania terenowe młodej grupy wulkanicznej Andahua, w południowym Peru. Została ona poznana zaledwie 45 lat temu i do chwili obecnej nie określono definitywnie jej zasięgu i genezy. Największym obszarowo i jednocześnie najbogatszym w produkty wulkanizmu grupy Andahua jest rejon Doliny Wulkanów. Lawy zwartą pokrywą wypełniają tę dolinę, między Misahuanca a Ayo na długości około 60 km. W trakcie prac zidentyfikowano około 150 centrów erupcyjnych, w tym: stożki piroklastyczne o wysokości 50-300 m oraz bardziej liczne kopuły i szczeliny lawowe. Morfologia i rozprzestrzenienie skał grupy Andahua wykazują pewne związki z tektoniką i budową geologiczną podłoża.
In 2003,2004 and 2006 small groups of geologists of AGH - The University of Science and Technology in Kraków investigated young Andahua volcanic group of Southern Peru. It was identified first some 45 years ago but its extension is not definitely determined yet. The greatest area of the Andahua group, where at the same time the volcanism products are the most common, is the Valley of Volcanoes. This valley, between the Misahuanca and Ayo, is covered by a dense cover of lava, which is about 60 km long. Field work resulted in discovery of about 150 individual emission centres: apparent pyroclastic cones 50-300 metres high, and usually smaller lava domes and vents controlled by fractures. Morphology of the Andahua lava flows coalescing into composite lava fields as well as criteria for their stratigraphy and tectonic controls are given.

Opis:
The Andahua Group is a distinct cluster of typically monogenetic volcanoes located in the northernmost part of the Central Volcanic Zone in the Andes, characterized by small-volume lava domes and scoria cones. Seven volcanic clusters have been distinguished. Using satellite imagery, geological mapping, and fieldwork, we found a total of 103 lava domes, 43 scoria cones, and 3 small composite volcanoes. Most of the lava domes are monogenetic but 9 were formed by multiple eruptions. Petrogenetic models have been developed for the magma evolution of the Andahua Group. They show local crustal influence on the magmas generated, and possible controls on the magma pathway to the surface, and potential segregation. Local compositional variation of the crustal rocks is inferred to have a strong influence on the magma that ascends through the thick continental crust. Assimilation and contamination by deeply seated granitoids of the Arequipa and Paracas massifs are also inferred to play a role in the final magmatic products. Future activity with gas emissions from the Andahua Group volcanoes may cause hazardous conditions for tourists.

The volcanic field of Harrat Khaybar north of Al-Madinah, Saudi Arabia contains rare examples of white volcanoes comprised mainly of the felsic rock comendite. The obsidian that occurs in association with the white comendite was exploited and worked by Neolithic inhabitants of the area. The white volcanoes are surrounded by more recent black basaltic lava fields that follow the pre-existing topography and display both aa and pahoehoe flow structures. Although situated only 60 km from a busy motorway, the volcanic area is remote and all necessary safety precautions must be taken in order to visit the volcanoes.

Opis:
Purely effusive activity built up a sequence of nine lavas on Úhoš' Hill. The oldest erupted lavas are tephrites/basanites (28.66 ± 1.06 Ma) and are of slightly evolved character. These are overlain by more differentiated alkali basalt. The succession continues with picrobasaltic lavas rich in phenocrysts (ankaramites 26.38 ± 1.04 Ma). The entire succession is crowned by alkali ba alt lavas (22.09 ± 0.73 Ma). All lavas appear to be emitted from a common conduit. With respect to geochemical and isotopic data, how ever, the studied sequence could not be interpreted in terms of the exhausting of a simple magma chamber. We propose the role of a more complex reservoir or, of two independent reservoirs attached to a single conduit system. The tephrites/basanites and picrobasalts (ankaramites) are closely related, the latter being derived by accumulation of mafic phenocrysts, namely clinopyroxene. The bas alts form an other group differing from the tephrites/basanites and picrobasalts in more evolved isotopic compositions of Sr and Nd as well as in in compatible-elementratios. The isotopic composition of the lavas seems to reflect mixed man tle sources derived from the European Asthenospheric Reservoir through the addition of components similar to Enriched Mantle (EM 1 and EM 2). The basalts originated by fractionation of different magma batches that contained a higher proportion of the enriched mantle component(s) or that were more contaminated with crustal material.

Opis:
The Quaternary Andahua volcanic group in southern Peru has been studied by present author since 2003. The Andahua Group stretches out at intervals within an area, which is 110 km long and 110 km wide. Seven regions bearing centres of volcanic eruptions have been distinguished: the Valley of the Volcanoes, Antapuna, Rio Molloco, Laguna Parihuana, Rio Colca Valley, Jaran, and Huambo. The Valley of the Volcanoes, where the Andahua Group was identified for the first time, contains the biggest variety of volcanic landforms. The valley is covered by a nearly 60 km long, continuous cover of lava flows. 165 individual eruption centres of the Andahua Group were distinguished including apparent pyroclastic cones, 50–300 m high, and usually smaller lava domes and fissure vents. Domes, eruptive vents and lava craters greatly outnumber pyroclastic cones. Most commonly, lava flows start from lava domes or craters. Small domes are often aligned along their feeding fissures. Lava domes and pyroclastic cones of the Andahua Group are aligned mainly along N–S and WNW–ESE trending fault systems. Projection points of the analysed Andahua lavas on the TAS diagram concentrate in the lower part of the trachyandesite field, entering also the basaltic trachyandesite or trachyte/trachydacite fields.

Opis:
Through the tabular morphology of northwestern part of the Middle-Atlas in Morocco, numerous uncovered monogenetic volcanoes arise structured of pyroclastic product layers and lava flows. Our fieldwork results witness a wide-ranging volcanic shape spectrum, as cones, maars, tuff-rings, and cone-maar mixes, generally associated with a later lava flow discharge that could develop many surfaces and appearances. There are withal sundry eruptive products such as pahoehoe lava, scoria, tuff, lapilli, peperites, base-surges, bombs, etc. This monogenetic volcanic field of practically 1000 km2 offers remarkable eruptive landforms, referred to as the largest, and the youngest volcanic field in Morocco, which consists of a large area within the Ifrane National Park. This fieldwork study provides a renewed volcanic geomorphological classification table and GIS data to be used by a wide public range for both educational and geo-touristic interest and access effectively to such a high-mountain natural museum. In the event that these volcanic structures were appropriately dealt with, the high educational scientific content and the notable touristic vocation would almost certainly create business openings and new financial wages for neighborhood populaces. This work focuses to share our outcomes and emphases the scientific value about the monogenetic volcanic field around the tabular Middle-Atlas in Morocco.

The article presents the approach to the design process of acoustic panels based on the scientific research. This approach is based on combining the technical and the design competences to develop the innovative product value for the concept of acoustic panels. The article presents the concepts of two new acoustic panels – an absorbing and scattering panel and a panel reflecting sound waves. The first part of the article presents the starting point for the presented project – the acoustic research and the inspiration for both types of presented solutions. Next, the materials possible to use were discussed, which could reproduce the natural acoustic properties of the lava and glacier caves. The next part presents consecutive stages of the product development in a modern form, ensuring the expected acoustic properties. The last part of the article presents a fully functional solution and proposes further research and development directions.

Opis:
In the Kraków-Lubliniec section of the major Hamburg-Kraków-Dobrogea Fault Zone (HKDFZ), the Stephanian-Early Permian magmatic activity was simultaneous with subsidence/uplift of formed blocks. In the proximity of the uplifted areas the sedimentation started with fanglomerates, distally passing into playa siltstone and was accompanied by volcanism. In the Nieporaz-Brodła graben, basaltic trachyandesite a-a lava flows with autoclastic breccias reach ca. 150 m in thickness. The weathering recorded as adhesive rims around breccia clasts reflects palaeosoil formation during quiescence periods between the eruptions. The eruptions were effusive although scoriaceous lava indicates high volatile content of the magma. The water content before eruption had to be over 2 wt. percent. Only then the crystallisation model predicts accurately the type, composition and order of the crystallising phases. Thus, the basaltic trachyandesite magma originated from a source containing hydrous phase (i.e., amphibole or phlogopite). All the studied basaltic trachyandesites had fayalitic olivine on their liquidus reflecting the crystallisation stage in a magma chamber at crustal depths. During final decompression on the magma ascent due to water exsolution, the olivine was followed by plagioclase, spinel, augite, ilmenite, apatite, K-feldspar and residual high-K rhyolitic glass. The high potassium content of these volcanics was thus a primary feature reflecting the source geochemistry and differentiation trend, and its consequence was potassium metaso- matism. Due to water exsolution the glass was altered, however, homogenous interstitial glass survived in some rocks. The glass is strongly enriched in incompatible trace elements, showing that it is a highly fractionated residual melt fraction of the basaltic trachyandesite magma. Thus, the glass geochemistry reflects the trend of fractional crystallisation indicating that co-occurring K-rich felsic rocks were not derived from the same magma. All the basaltic trachyandesites studied have calc-alkaline to alkaline affinity. They contain fayalitic olivine and are low in MgO <5 wt. %, Cr and Ni, the features characteristic for evolved magmas. They show significant negative Sr/Sr*> 0.5-0.80 and small Eu/Eu* > 0.9-1.0 anomalies suggesting fractionation of plagioclase. The Eu/Eu* anomaly is probably compensated by amphibole retaining in the source. Negative Nb, Ti anomalies suggest Fe-Ti oxide fractionation characteristic for calc-alkaline evolution trend. A significant enrichment in LREE relatively to HREE (La/Yb > 10) indicates subduction-related metasomatism. However, the described tectonic context is inconsistent with subduction related characteristics. Concluding, the observed geochemical characteristics indicate remarkable role of water in magma evolution. The volcanism was related to strike-slip dextral movement along the Kraków-Lubliniec section of HKDFZ, transformed into crustal extension and subsidence, the features typical for the formation of pull-apart basins, in the late stages of the Variscan orogen evolution.

Opis:
Based on the assumptions of the circular economy model and sustainable development, we are currently looking for natural and ecological materials in terms of wastewater treatment of pollutants. This article presents the research of three mineral materials - lava rock (LR), lightweight sintered aggregate (LSA) and lightweight clay aggregates (LCA) used as filling of filtration columns for the treatment of real wastewater. The filtration process was carried out under various hydraulic loads in two columns, one of which was additionally supported by the aeration process. The post-treated sewage was characterized by the following parameters: COD (chemical oxygen demand), TOC (total organic carbon), phosphate phosphorus (P-PO4 ), total nitrogen (TN) and total phosphorus (TP). Among the hydraulic loads applied, the most optimal loads were OhI = 0.25 m3/(m2·h). Certyd turned out to be the most effective with supporting filtration with the aeration process in removing organic compounds (reduction of 65.1% COD and 38.2% TOC at OhI ). Lava rock seems to be a promising material reactive in terms of removal of biogenic compounds such as nitrogen (efficiency 23.8% at OhI ) and phosphorus (64.2% reduction of TP at OhI ) and organic compounds (21.4% reduction of TOC at OhI in conditions without aeration). LCA shows the best efficiency in sorption of phosphorus compounds (41.6% reduction of TP at OhI ) and organic compounds (21.4% TOC reduction at OhI under non-aerated conditions).

Artykuł przedstawia walory geoturystyczne grupy wulkanów Kluczewskiej Sopki na Północnej Kamczatce. Pokazano położenie półwyspu Kamczackiego na tle aktualnych granic płyt litosferycznych oraz wyjaśniono genezę i budowę tzw. Korjacko-Kamczackiego pasa wulkanicznego. Geotektoniczne położenie Kamczatki w strefie "okołopacyficznego pierścienia ognia" umożliwia zapoznanie się na tym obszarze z przejawami współczesnego wulkanizmu (wulkany tarczowe, stratowulkany, kopuły ekstruzywne, kaldery, pokrywy ignimbrytowe, potoki błotne (lahary), ekshalacje gazów i par, czy wykwity siarkowe). Obok działalności wulkanicznej o niezwykłej atrakcyjności geoturystycznej tego obszaru decyduje urozmaicona rzeźba górska, modelowana przez lodowce górskie, procesy wietrzenne i erozję rzeczną.
The paper describes the geotouristic valours of the Klyuchevskaya group of volcanoes in the Northern Kamchatka. The relationships are presented between the Kamchatka and the recent boundaries of crustal plates, then the genesis and the structure are explained of the Koryak-Kamchatka volcanic belt. The geotectonic position of Kamchatka as a part of the "Circumpacific Ring of Fire" enables us to recognize the manifestations of the recent volcanism (shield volcanoes, stratovolcanoes, lava domes, calderas, ignimbrites, lahars, gas and vapour exhalations, native sulphur encrustations). Apart from volcanic activity, the exceptional tourist value of the Northern Kamchatka is the high- mountain relief shaped by glaciers, weathering and river erosion.
