Opis:
The paper presents the 12-years discharge variations of the three springs located within the Pieniny National Park. The background was the observations of the water table variation in the springs and seasonal measurements of the springs discharge, which made the possibility of calculation of the rating curves. Generally, the Pieniny springs are characterized by low discharge. The mean discharge of the springs studied for the period 2003–2014 was as follows: spring of the Potok pod Wysoki Dział – 1.66 dm3s‒1, spring of the Kotłowy Potok – 0.26 dm3s‒1, seasonal spring of the Kirowy Potok – 0.10 dm3s‒1. Variations of the springs discharge are different due to the fact that particular spring drain separate, and relatively small groundwater reservoir. First of all, the influence of the many-years variation in the sum of atmospheric precipitation as well as the amount of infiltrating meltwater can be observed. Observations with monthly distribution showed the characteristic shift between maximum discharge of the spring and the sum of atmospheric precipitation (about 1 month shift) as well as the thawing period (1–3 months shift). Presumably, during dry seasons the springs have mainly the thawing regime, in the normal (balanced) seasons – the thawing-precipitation regime is dominant, and during the wet season – the precipitation-thawing regime prevails. In the years 2012 and 2013 the sudden decrease of discharge of the Kotłowy Potok and Kirowy Potok springs have been observed which is in well agreement with the hydrogeological drought identified in Poland.

Opis:
The area around the city of Barberton in the north-east part of South Africa is built of varied rocks belonging to the so-called Barberton Greenstone Belt (BGB), which are among the oldest (Paleo-and Mesoarchaic) and best preserved in the world. Their observation directly in the field is possible thanks to the “Barberton Makhonjwa Geotrail” created in 2014. The article briefly presents the geological structure of this area and provides important information on the development of the Earth in the Archaic, in the light of the latest research. Examples of representative outrops of BGB rocks and the close relationship between the geological structure and morphology are presented. The important raw materials of this area, including rich gold deposits (“Sheba”and others), known since the 19th century, are also mentioned.

Opis:
The paper discusses the results of stationary limnimetric observations conducted since 2003 for three springs located in Pieniny Czorsztyńskie within the Pieniny National Park. Current knowledge on the hydrogeological regime of the examined springs, and especially their response to precipitation, meltwater supply and type of discharge recession during periods with no water supply indicated that all the springs drained small local groundwater reservoirs characterized by rapid water exchange. One of the springs was ofperiodic nature. Relatively short (14 years) observational series on spring discharge were used to identify the periods of low flow and hydrogeological drought. In order to achieve this goal, total precipitation and snow cover thickness were analyzed in individual hydrological years. Low flow periods were defined as those when the spring discharge dropped below an average value calculated on the minimum annual spring discharge for the observation period. Identification of the hydrological drought was based on the interpretation of moving average values, which allowed for the elimination of changes in spring discharge due to seasonal fluctuations and random deviations. The basis for the determination of hydrogeological droughts were the deviations ofmoving average values from the mean value over the entire observation period. The methodology was similar to the ways of determining hydrogeological drought described by other authors in mountainous areas of Poland. Periods of the most severe hydrogeological drought in the Pieniny occurred in the 2003-2004, at the turn of 2005 and 2006, in 2012, and in the 2015-2016. Specific dates of drought occurrence for different springs were variable and depended on the morphological location of the spring and local hydrogeological conditions.

Opis:
The SW margin of the Zavkhan terrane is significant for research on Paleozoic amalgamation of the Central Asian Orogenic Belt (CAOB). The study area is located in the western part of the Khasagt Mountains, western Mongolia. We present a new preliminary K-Ar dating of metasedimentary rocks from the Yargait Formation which were deformed during collision of the Zavkhan terrane with the Lake Zone terrane. Our results include two dating that are similar to earlier data by other authors (Stípskáetal., 2010; Bold et al., 2016b). The first dating equal to 544.1 ±13.7 Ma can be interpreted as the age ofmetamorphism and the subduction of the SW margin ofthe Zavkhan terrane under the Lake Zone terrane during the late Ediacaran-early Cambrian. The second dating of 441.1 ±11.7 Ma indicates the Late Ordovician - Silurian regional extension event.

Opis:
The authors carried out petrographic, mineralogical, and chemical analyses (bulk chemical composition and microanalyses of mineral chemical composition) of NWA 4446 carbonaceous chondrite. NWA 4446 chondrite is classified as CV3, S2, W2. This meteorite is a rock fragment most likely from one of the C-type asteroids orbiting the Sun in the outer part of the asteroid belt. It represents the matter formed at the earliest stages of the formation of extrasola bodies in the solar system. As a result of the research, the authors documented a wider range of variation in the chemical composition of olivine crystals (Fa: 0.67-46.57 mol%) in the matrix and chondrules, and a much narrower range of variation in the chemical com- position of pyroxene crystals (Fs: 0.90–3.35 mol%) against the data used for the classification of the meteorite. The characteristics of the chondrules, ranging in size from 0.5 to more than 1 mm, allowed concluding that they constitute about 60% of the meteorite’s vol- ume, in which they form many structural and mineral varieties PO, POP, BO, PP and RP chondrules were observed. The remaining 40% of the chondrite volume is a matrix consisting of small crystals of pyroxenes, olivines, glass, as well as opaque minerals: sulphides, FeNi alloy, native copper and gold grains, carbonaceous substance, and compact CAIs. The mineral and chemical composi- tion of CAIs shows that their dominant mineral is melilite, accompanied by diopside and spinel. The chemical composition of spinel and diopside is very similar to their total chemical formulas, while the composition of melilite shows a significant sodium deficiency. Among the opaque minerals, one phase of the FeNi dominates - awaruite (Ni 3 Fe), and sulphides are represented by troilite (FeS) and mackinawite ((Fe,Ni) 9 S 8 ). Moreover, grains of native copper with an admixture of gold and grains of native gold with an admixture of platinum, nickel and copper with a size of several μm were identified. Taking into account the admixtures contained in the above-mentioned opaque minerals (mainly Co and Cu), the parent rock of the carbonaceous chondrite NWA 4446 can be considered to have been mineralized with Fe, Ni, Co and Cu ore minerals with the content of Au and Pt. This means that, we can expect deposits of native forms of the above-mentioned metals and sulphides on the parent bodies of carbonaceous chondrites of the CV group - C-type asteroids.

Opis:
Doctor Bolesław Bujalski (1888-1945) graduatedfrom Lviv University to become an outstanding Polish geologist and cartographer. His major fields of expertise included tectonics and structural geology of the Flysch Belt of the Outer Eastern and Western Carpathians and oil potential in these regions. His professional career included work for a petroleum company Towarzystwo Naftowe "Galicja" S.A. and the Polish Geological Institute. During the First World War, he served in the Austro-Hungarian army. Hefought on the Russian and Italian fronts and advanced to the rank ofLieutenant. After the war, in November 1918 Doctor Bujalski he joined the reborn Polish Army in the rank of Captain and took part in a battle called the Defense of Lviv in the Polish historiography. He also fought in the Polish-Soviet War in 1920. For his distinguished merits, he was awarded the highest military distinction of Poland, the Silver Cross of the War Order of"Virtuti Militari". During the Second World War, he headed the Relief Committee of the Central Welfare Council in Stanisławów, a charity organization operating in Poland under the German occupation. He tried to continue these activities after the entry of the Red Army into the Stanisławów area in 1944 to be soon arrested by the Soviet security services (NKVD) and die in a jail most probably in early 1945.
