Microprobe analyses of phengite and biotite in granitic mylonites from the Simplon Shear Zone

This dataset presents in-situ microprobe analyses of phengite and biotite in metagranitic mylonites from the exhumed footwall of the Simplon Shear Zone, central Alps. The chemistry provided here was used together with careful microscopy to distinguish relict grains/zones from grains that were grown, recrystallized or otherwise re-equilibrated during deformation.

本数据集收录了阿尔卑斯中部辛普朗剪切带（Simplon Shear Zone）折返下盘的变花岗质糜棱岩（metagranitic mylonites）中多硅白云母（phengite）与黑云母（biotite）的原位微探针分析数据。本数据集所载的化学成分数据结合精细显微观测，可用于区分变形过程中残留的矿物颗粒/区域与新生、重结晶或发生其他再平衡作用的矿物颗粒。
