Major element analyses of plagioclase and pyroxene from gabbros of the layered mafic Dufek Intrusion

Abstract: EMP analyses of plagioclase and pyroxene from gabbros sampled from the layered mafic Dufek Intrusion. The samples were collected in the austral summer 2006/2007 from the Dufek Massif, Forrestal Range, Pensacola mountains, Antarctica.

摘要：针对采自层状镁铁质杜费克侵入体（layered mafic Dufek Intrusion）的辉长岩（gabbros）中的斜长石（plagioclase）与辉石（pyroxene）开展电子探针显微分析（Electron Microprobe Analysis，EMP）。样品于2006/2007年南半球夏季采自南极洲彭萨科拉山脉（Pensacola mountains）福里斯特尔岭（Forrestal Range）杜费克地块（Dufek Massif）。
