@article{oai:nipr.repo.nii.ac.jp:00004634, author = {Ikeda, Yukio}, journal = {Proceedings of the NIPR Symposium on Antarctic Meteorites}, month = {Mar}, note = {P(論文), The ALH-77005 shergottite is a cumulate gabbroic rock consisting of brown olivine, low-and high-Ca pyroxene, plagioclase glass, Ti-poor and-rich chromite, ilmenite, whitlockite, and sulfides. Chromites in ALH-77005 show four types of chemical zoning, and these types suggest multiple magma mixing. Some plagioclase glass has plagioclase rims, and the rims were produced from plagioclase melts by rapid crystallization. Ubiquitous occurrences of plagioclase glass and shock-melt pockets that were produced by in-situ melting indicate that ALH-77005 has experienced shock pressures ranging from 50 to 80 GPa.}, pages = {9--29}, title = {Petrography and petrology of the ALH-77005 shergottite}, volume = {7}, year = {1994} }
