喜马拉雅穹隆带错那洞穹隆电气石花岗岩电子探针分析

北喜马拉雅穹隆带错那洞穹隆就位大量含电气石淡色花岗岩，对于电气石淡色花岗岩中电气石主量元素分析，采用对单颗粒核部到边部的主量元素丰度探测，探测方法为电子探针。
数据来源与加工：电子探针EPMA测试，测试实验室：北京大学 造山带与地壳演化教育部重点实验室 电子探针实验室；探针薄片中电气石矿物元素丰度测试；
数据质量：元素丰度误差<0.1%.
数据应用于前景：分析淡色花岗岩源区及其差异，以及探讨流体作用的改造。

A large number of tourmaline-bearing leucogranites were emplaced in the Cuonadong Dome of the North Himalayan Dome Belt. For the major element analysis of tourmaline in tourmaline-bearing leucogranites, core-to-rim major element abundance detection of single tourmaline grains was conducted using electron probe microanalyzer (EPMA).
Data Source and Processing: Electron Probe Microanalyzer (EPMA) tests were performed at the Electron Probe Laboratory, Key Laboratory of Orogenic Belts and Crustal Evolution (Ministry of Education), Peking University; Element abundance analyses of tourmaline minerals were carried out on thin sections.
Data Quality: The analytical error of element abundances is less than 0.1%.
Data Application Prospects: This dataset can be used to analyze the source regions and their differences of leucogranites, as well as to discuss the modification effects of fluid activities.
