The garnets of the schlich of the winter coast (the White Sea)
During an expedition to the White Sea Winter Coast, samples of schlich with numerous garnets were collected. The coast itself is primarily a set of high steeps of sandstones and mudstones with no garnets. On the beach, however, there are numerous pebbles of metamorphic rocks, and many of them contain garnets. They were brought there by the Quaternary glacier and the present day glacier activity. Their source could be the existing or fully eroded metamorphic rocks of the Kola Penninsila and Northern Karelia.\r Goal of the research: To discover the possible origin of the garnets.\r Tasks: 1) To analyze the structure and the chemical composition of the garnets. 2) To study the works on the garnets of the Kola Penninsila and Northern Karelia in order to compare the information to the results of the analysis.\r Methods: 1) Granulometric analysis; 2) Magnetic and electromagnetic separation; 3) Microscope study of the garnets; 4) X-ray diffraction analysis; 5) X-ray fluorescence analysis. \r RESULTS\r 1. The sample garnets could be divided into two types: the bright red and the pale pink.\r 2. Both types are almandines with spessartine components. The pale-pink one contains Arizona ruby components, and the bright red contains andradite ones. \r 3. Only a few samples from Khangaz Varaki, Malye Keivy, and Tersky Coast are similar to the garnets that we collected. It is possible that the glacier brought them from the Kola Penninsula, but it is also possible that the rocks, where the glacier brought our garnets from, have been totally eroded.
Pleistocene mammals of a river basin of Adycha
The paper represents the results of study of remains of mammalians which inhabited the Adycha-River basin (Verkhoyansky Region) during the Pleistocene Epoch. All studied materials belong to the Museum of Paleontology and Ethnography of the Adychinskaya Secondary School. For a long time, People have been finding ancient animal bones on the Adycha-River banks, and since 1955, the teacher, Bozhedonov Nikolai Gerasimovich, has been organizing exploring local lore expeditions for school children purposed for mammoth fauna investigation and material collection for the school museum. In this research collected material was classified, measurements of the Pleistocene Period animal bones were made. On the basis of it we came to conclusion that during the Pleistocene Epoch, very rare species of animals inhabited the Adycha-River basin. To our opinion, the Adycha-River basin is a unique site for research activity. Comparative measurements of the Pleistocene Periods animal bones were made. Of flu work we know measurements of the Early and Middle Pleistocene Period elephant’s bones which inhabited the Adycha-River basin. Elephants inhabited with mammoth. To our opinion, they didn’t yield to size to mammoth. In that time the Adycha-River basin, was been inhabited by camelopard, bison and Soergelia.\r Museum has 2 skull’s fragments and ovibos fronts part of horny stream. Geological age which is Early Pleistocene or late Pleistocene. These bones concern to Praeovibos. Distance between horns is more 100 mm. If we compare with ovibos skull of the Late Pleistocene we see that distance between horns is longer for the 10 time. We couldn’t found such comparisons at scientist’s works. It results that the more distance between horns is longer the more ancient, and skull’s sizes are much less.\r 7-8 km lower of Betenkes, in disclosing “?????? ???????” and sand bank “??????”, was been founded 3 crag’s part of skull of Soergelia, metacarpal bone and 2 skull’s fragments with horns part. On the Adycha-River basin was bun founded above all quantity of soergelias remains.\r In the Pleistocene Period inhabited a lot of horses. Which remains he have now. Our horse’s height in crest is from 142 to 156 sm. And what about of horses of the Early Pleistocene, it is more than 230 sm.\r Molar teeth of the Early Pleistocene Epoch horse are more for the 2.5 times than of contemporaneous analog.
