Opis:
Celem niniejszych badań było porównanie efektów usuwania związków fosforu (ortofosforanów) z wód z dodatkiem ortofosforanów, z wykorzystaniem dwóch metod: metody elektrokoagulacji (z wykorzystaniem procesów elektrochemicznych z użyciem prądu stałego) i metody roztwarzania metali (z wykorzystaniem procesów korozyjnych).
There is a search in progress for some efficient methods of removing biogenic compounds from the treated sewage. Unquestionably, effective methods of phosphorus compounds removal include precipitation methods. The most common is the chemical precipitation method based on applying iron, aluminium or calcium salt to the solution and electrocoagulation. These methods utilise low solubility of metal phosphates and their sorption on the surfaces of the forming agglomerates. The real mechanism is quite complicated and consists of transforming phosphorus compounds into insoluble forms, and then separating them from the sewage by flotation, sedimentation, filtration. The method of iron solution should also be accounted into similar physical and chemical methods. The main difference between the aforementioned methods lies in the way of applying the precipitation agent to the solution. The method of iron solution is based on similar premises as the electrocoagulation method, however, metal ions here are dissolved into the solution as a result of spontaneous corrosion processes and, due to the further transformations in the sewage environment, they are to be responsible for phosphorus removal. The article presents comparative tests on a laboratory scale. The electrocoagulation method and metal digestion method were compared with regard to the effectiveness of orthophosphates removal from synthetic sewage. The comparison of both methods suggests that they can bring similar results of removing phosphorus (ortophosphates) from sewage. The process of reduction of concentration of orthophosphates in sewage occurs faster when the electrocoagulation method is used. However, with a longer test duration, better results are achieved using the metal digestion method. It was also noted that both methods introduce different amounts of iron into the solution. The methods differ with regard to the amount of iron remaining in the sewage in a suspended form. This indicates a better use of iron ions in the metal digestion method and it slightly limits the problem of an excessive amount of sludge.

Opis:
The Hoanh Bo Basin has developed over multiple periods since the Miocene period in association with the tectonic activity of the Chi Linh-Hon Gai and Trung Luong Faults. The basin is filled with Neogene continental sediments, comprising mainly polymictic conglomerates, sandstones, siltstones, claystones, and shales. Coarser-grained polymictic deposits predominate along the northern and western margins of the basin, whereas different types of siltstones, claystones, and sandstones occur in its centre, as well as along its southern and eastern parts, toward the Ha Long Bay. The conglomerates and sandstones are composed mainly of quartz and sedimentary rock fragments, and a small amount of mica. Cement is mainly built of iron-oxide, clay or carbonate mud. The source area for the Hoanh Bo Basin sediments was located in the close vicinity of the basin. It was built of strongly weathered rocks of the Hon Gai, Ha Coi, Cat Ba Formations.

Opis:
The Cao Bang Basin is the northernmost of the basins related to the Cao Bang-Tien Yen Fault Zone in northern Vietnam. The basin is filled with a thick series of continental deposits. However, the exact age of the sedimentary basin infill has been under discussion for a long time. Because of new published data, the authors have decided to revisit this basin. Palynological data has allowed us to assign the Cao Bang Basin infill to the Lower Oligocene PC1 complex of the Shangcun Fm. (southern China). Among the saccate grains of gymnosperms, the domination of Cathaya and Pinus was observed, whereas angiosperms are represented by Carya, Celtis, Hammamelidaceae, Ulmus and also Pterocarya, Quercus, the Castanea–Castanopsis–Lithocarpus group, and the Loranthaceae. Among pteridophytes occur Laevigatosporites, Osmundaceae, and Pteris. The sedimentological features of the Cao Bang Basin are distinct from those of other basins from the Cao Bang-Tien Yen Fault Zone. The basin is filled with a wide variety of clastic deposits, from some of coarse-grained, alluvial-fan origin, through sandy beds of fluvial origin up to fine, organic-rich lacustrine deposits. The coarse-grained lithofacies are built of clasts derived mainly from local sources. The sandstones from the basin equally are submature or immature. They contain a lot of lithoclasts, the composition of which depends on the sample location within the basin. The potential source area is composed of older sedimentary units and of granitic rocks. The geochemical samples studied reflect the geochemical composition of silicic source rocks with only a minor contribution of basic components. The succession that fills the basin is interpreted as a typical fill for relatively long-lasting evolving half-graben or strike-slip basins. Moreover, the basin is partly occupied by a subsequent present-day sedimentary basin of Quaternary age.

Opis:
The Miocene Carpathian foredeep basin in Poland (CFB) developed in front of the Outer Carpathian fold-and-thrust belt, at the junction of the East European craton and the Palaeozoic platform. 3D seismic data, cores and well logs from Sokołów area (vicinity of Rzeszów) were used in order to construct new depositional model of the Miocene succession of the Carpathian foredeep. The gas-bearing Miocene infill of the CFB is characterized by a shallowing-upward trend of sedimentation and consists of hemipelagic, turbiditic and deltaic and nearshore-to-estuarine facies associations. Lowermost part of the Miocene infill seems to has been deposited from the North. Such direction of sediment supply was related to influence of existing relief of the pre-Miocene basement, where very deep (up to 1,5 km) erosional valleys cut into the pre-Miocene (Precambrian) basement due to inversion and uplift of the SE segment of theMid-Polish Trough are located. Upper part of theMiocene infill reflects sediment progradation from the South, from the Carpathian area into the foredeep basin. In the Rzeszów area existence of the so-called anhydrite-less island, i.e. relatively large area devoid of the Badenian evaporitic cover caused by the post-Badenian uplift and widespread erosion of evaporites,has been postulated for many years. Interpretation of 3D seismic data showed that such model should be abandoned. In the studied part of the CFB, Late Badenian evaporitic sedimentation was restricted to the axial parts of deep paleovalleys. Evaporites deposited in these valleys have been rarely encountered by exploration wells as such wells were almost exclusively located above basement highs separating erosional paleovalleys, hence giving incorrect assumption regarding regional lack of evaporitic cover. It is possible that in axial parts of these valleys important gas accumulations might exist, charged from the South and sealed by the Badenian evaporites.
