Mineral chemistry of Upper Paleozoic komatiites of Mashhad, NE Iran

The data obtained from the EPMA analysis of the major minerals that make up the Mashhad komatiites. In these komatiites, the ultramafic portions contain olivine with different morphologies, which set in a matrix of clinopyroxene and accessory chromian spinel and plagioclase. The mafic sections predominantly consist of clinopyroxene and plagioclase.

本数据集源自马什哈德科马提岩（Mashhad komatiites）主要造岩矿物的电子探针显微分析（Electron Probe Micro-Analysis，EPMA）数据。该科马提岩的超镁铁质岩段包含不同形貌的橄榄石，这些橄榄石赋存于由单斜辉石、副矿物铬尖晶石及斜长石组成的基质中；其镁铁质岩段主要由单斜辉石与斜长石构成。
