THE GALKIV METEORITE - A NEW H4 CHONDRITE FROM UKRAINE

The Galkiv chondrite is a single 5 kg stone that fell in the Chernigov region of Ukraine on 1995 January 12. The composition of olivines in the meteorite indicate that Galkiv belongs to the H group of ordinary chondrites. Although the heterogeneity of olivine corresponds to a pet rologic type 5 and the heterogeneity of low-Ca pyroxene suggests the c hondrite is type 3, clearly defined chondrule boundaries, the presence of clinopyroxene, cryptocrystalline glass and rare grains of feldspat ic plagioclase, structural evidences of shock metamorphism and very lo w level of terrestrial weathering allow us to classify the meteorite a s an H4 chondrite of shock stage S3 and weathering grade W0.
