Meteorite Crater Ilyinets Impactite Breccia Crater Ukraine Impact breccia Suevite。CERTIFICATE IMCA 4167。IL 7040。This specimen is about 62 * 34 * 13mm。weight 18,85g.。 。· 400 million years ago the Earth was in the initial stages of formation of Pangea (Supercontinent, "All Earth"). The meteorite heated to the melting point due to friction with the atmosphere, and in the form of a fireball, after hitting the earth, exploded.。· The initial diameter of the meteorite is 230-300m, the speed of fall is more than 10 km/s.。· The energy during the explosion - 10k times exceeded the total capacity of all the world's nuclear weapons stockpiles.。· The magnitude of the pressure was millions of atmospheres, the temperature was over 3000 degrees.。· The solidified upon cooling melts crust is the impact and it assimilated meteorite substance.。· In the Illinetsky crater, the content of nickel, iridium, cobalt in the proportions of meteorite rocks is higher than that of the earth. Impact diamonds were first found here in 1974. This is the second crater on Earth where was found these gems and the world's largest agate. According to scientists, the nucleus of the meteorite in Illinetsky crater lies approximately 700 meters deep.。· At the base of the crater are gneisses and blacks, leucocratic pink granites and pegmatites, as well as more rare types of rocks, which are represented by amphibolites. on the modern erosion surface, loose Quaternary deposits are deposited directly on the rocks of the coptogenic complex and the crystalline base complex.。Institute of Geological sciences ,O.Gonchar St.55-b,Kiev,01054,Ukraine.。The aerodynamically shaped, zoned bombs composing shocked granite or quartz cores and glassy crusts, occur in the fallback suevites of the Ilyinets impact crater in Ukraine. Formation of the bomb glassy coating by condensation of high temperature silicate vapor on the surface of the granite clasts on their trajectory trough the vapor plume was suggested [1, 2]. The INAA measurements of the bomb composition have shown enrichment of the glassy crust with the REE relatively to the bomb cores, impact melt rocks and target rocks of the crater.。Three bombs were analyzed for major element content with the XRF method and six ones for trace element content with the INAA. The main features of major element distribution in the bombs are high potassium (11 wt.% K2O in the cores and 15 wt.% in the glassy crusts) and low sodium content (0.5 wt.% Na2O) compare to that of target granites (4.57 wt.% K2O and 3.6 wt.%Na2O [3]).。The compositions of glassy crusts are uniform and do not depend on the core composition. Unusually high content of the REE in the glasses about 2.5-3.5 times higher than its content in the cores, impact melt rocks and granites. In the same time the bomb cores are depleted in the light REE region (La, Ce, Nd), while contents of the other REE is very similar with their content in impact melt rocks and target rocks of the crater.。Discussion. The structure and composition of the Ilyinets zoned bombs differ from that of glassy bombs of Ries and Elgygytgyn craters [2, 4] but are similar to zoned bombs from the Popigai crater formed by accumulation of melt droplets on the surface of gneiss clasts in a vapor plume [5]. The high temperature condensation of potassium-rich silicate vapor on the surface of granite clasts at their flight trough the ejecta plume was supposed for Ilyinets bomb formation [1]. In the same time enrichment with potassium of suevite and the upper layer of impact-melt sheet as a result of post-impact hydrothermal activity is suggested [3]. The high REE contents and their distribution in the zonal bombs could not formed by a hydrothermal process. We suggest that condensation of silicate vapor on the relatively cold surface of granite clasts in the high- temperature ejecta cloud is the main process of the bomb glassy crust formation, while accumulation of melt droplets and mineral clasts took part in this process too. The experimental impact evaporation of the silicate targets show enrichment of the condensate。with the REE [6]. It is suggested that evaporation and transportation of the REE in the plume may occur by formation of high-volatile complexes.。 ASTROBLEMES IN UKRAINE Vidmachenko A. P.。In territory of Ukraine been found 9 explosive craters. Most researchers believe, that all of them were formed by the fall of celestial bodies on the Earth. However, were expressed an opinion on the endogenous (terrestrial) origin some of them. Ukrainian crystalline shield due to it geological stability for a long time (more than 1.5 billion years) has the highest density of large astroblemes on the Earth's surface. This shield extending from the northwest to the southeast of almost 1000 km along the right bank of the Dnieper River. Maximum of its width is 250 km. All impact craters on the territory of Ukraine are under a large (100-500 m) thickness of organic sedimentary deposits. So their research was carried out with using wells. The largest Ukrainian astrobleme is Manevitsk. It is located in theVolyn’ region; has a diameter of 45 km; it originated, probably, around 65 million years ago. Ilyinetscrater located in Vinnytsia region. It is the oldest astrobleme of Ukraine. It was formed about 430 million years ago in the fall of an asteroid with a mass of ~40 million tons and a diameter of 230-300 meters. In the central part of the Ukrainian Shield is another unique geological structure: Boltysh crater. Its diameter is about 24 km. It originated 65,17 ± 0,64 million years ago when a meteoritefalling on the ground. Sometimes find that it confirms the theory of multiple impacts as the cause ofPaleogene extinction. Obolon’ crater has 20 kilometers in diameter; it is located in Poltava region on the northeast slope of the Ukrainian shield. It is formed 169 million years ago. Ternivka crater located on the outskirts of Kryvyi Rig; its diameter is 11-12 km, and age is 280±10 million years.Bilylivka crater is the impact structures with a diameter of 6.2 km; was formed in the fall of a meteorite about 165 million years ago. It is located in the western part of the Ukrainian shield in Zhytomyr region. Rotmistrivka crater located in Cherkasy region and has an age of 120 million years. This astrobleme has a diameter of 3 km and depth of 300 m. Astrobleme Zelenohayska formed in Kirovograd region and consists of two craters: larger has diameter 2.5-3.5 km, and smaller – diameter of 800 m. Age structures of both craters – about 8020 million years. Therefore, we can assume that they arose as a result of impact of two fragments of one celestial body. Thus, some features and composition of these structures may well be explained, for example, later volcanic activity on the territory earlier astroblemes or formation of explosive craters on existing volcanic areas.。Attention!。You can get a discount of 50% or more under the following conditions!。You are the representative。Museum。Geology or space exhibitions。Institute or other educational institution。 You are a researcher and you need this sample for research。To discuss the discount, contact me。We need an official letter on your letterhead, signed and, if possible, stamped, asking for a sample.。DELIVERY 。For the manufacture of your order I will need 2-3 days。At the moment the time of delivery:。America - 10-20 days。Europe - 7-18 days。Canada - 10-30 days。Asia - 15-30 days。Australia, New Zealand - 20-45 days。RETURNS & EXCHANGES。I gladly accept returns and exchanges。Contact me within: 14 days of delivery。Ship items back within: 30 days of delivery。The following items can't be returned or exchanged because of the nature of these items, unless they arrive damaged or defective, I can't accept returns for:。- Custom or personalized orders。- Perishable products (like food or flowers)。- Digital downloads。- Intimate items (for health/hygiene reasons)。Conditions of return。
