EN The time of fall of a meteorite and the appearance of the impact craters in Morasko have been documented by the thermoluminescene method, 14C dating, as well as palynological estimation. The extraterrestrial effect on the lithology and morphology of Moraska Góra (Morasko Hill) took place about 5000 [...]

PL Badano skład pierwiastkowy, skład mineralny i mikrostrukturę meteorytu pustynnego Al Haggounia 001 znalezionego w Maroku w 2006 roku. Do badań wykorzystywano analityczną mikroskopię eiektronową. Ustalono, że zarówno skład pierwiastkowy, jak i skład mineralny, a także mikrostruktura tego nowego mater[...]
EN Elemental composition, mineral composition and microstructure of Al Haggounia 001 meteorite found in 2006 were studied by analytical electron microscopy. It was established that orthopyroxene dominated by enstatite (En89-S2Fs16-10Wo1-2), sodic plagioclase (Ab81-84An10-12Or4-5), graphite, and oxidize[...]

EN The authors examined the bulk chemical composition of the Sołtmany chondrite which fell on April 30th, 2011 in Northern Poland. Based on the analysis of 47 elements, it was concluded that Sołtmany is representative of L-type of ordinary chondrites. However, compared to the average values observed in[...]

EN This paper presents the results of a mineralogical and petrological study of the Sołtmany meteorite, which fell on April 30, 2011 in northern Poland. The meteorite was found almost immediately after it fell and has been little altered by weathering. Sołtmany is not the only observed fall of an L6 ch[...]

EN Cosmogenic radionuclides were measured in two specimens of the Sołtmany chondrite (L6) that fell on April 30, 2011. The first fragment (154.9 g) was measured 12 days after the fall and the second piece (120 g), 53 days after the fall. Both fragments were measured by means of non-destructive gamma ra[...]

PL Krater meteorytu Gardnos znajduje się w Norwegii, ok. 125 km na północny zachód od Oslo. Cała struktura jest dobrze widoczna w terenie dzięki licznym odkrywkom brekcji impaktowych i utworów poimpaktowych występujących w okręgu o promieniu ok. 5 km. Główne typy skał impaktowych w rejonie krateru Gard[...]
EN The crater of the Gardnos meteorite is located in Norway, about 125 km north-west of Oslo. The structure is well seen due to the outcrops of impact breccias and post-impact deposits that form a circle with a radius of about 5 km. Main types of the impact rocks in the Gardnos area are the autochthono[...]

Meteorites
EN Three genetically different types of nanometer-sized mineral grains in meteorites can be distinguished based on literature and original data: (a) primitive condensates, (b) metamorphic grains, and (c) weathering products. The first of these groups were formed by condensation in a gas-dust nebula in [...]
