Petrographic and geochemical study of rocks at Shakiso, Ethiopia: no evidence for shock metamorphism
Journal of African Earth Sciences(1998)
摘要
We have performed field work and petrographic and geochemical studies on rocks from the area around Shakiso, Ethiopia, where the existence of an impact crater, based on the asserted presence of shatter cones and breccias, was previously suggested. We did not find any evidence that would support this claim.
