| Summary: | Abstract Amorphous substances, including glasses, are very important kind of value materials for numerous applications. Among the glasses the impact matter has especially high fundamental interest and use potential, being formed under extremely high PT conditions - up to hundreds GPa and thousands degrees Celsius. In this direction the detail studies of new natural occurrences with UHPHT impact glasses and their features are very actual fundamentally and probably potentially useful for new ideas for technologies. Our analytical studies of the UHPHT ribbonlike impact glasses of the Ust`-Kara area at the Baydarata Bay (Kara Sea, Arctic Ocean) revealed the presence a number of special features such as multilevel differentiation of impact melt and coesite abundance. The specifics of the Ust`-Kara UHPHT glasses rather point to bottom facies of the suevitic breccia. The observed impactites characteristics allow to see new geological importance of the studied Ust`-Kara suevites, allow to correct geological model of the impact structure. |
