青藏高原冈底斯西段革吉镇南矿物电子探针实验数据

数据为青藏高原冈底斯西段革吉镇南矿物电子探针实验数据。通过对探针片单偏光、正交偏光的观察，圈出所需测试元素含量分析的区域，在喷碳处理后对其矿物成分进行电子探针分析。分析测试工作在中国地质科学院矿产资源研究所进行，所用仪器为JEOL-JXA8230型电子探针，氧化物加速电压为15 kV，硫化物为20 kV，束斑直径为5 μm，标样采用天然矿物或国家标准合成金属，分析误差小于0.01%。麻木研究区Pb-Zn-Fe-Cu矿化区成矿矽卡岩内的主要矿物包括钙铁榴石、钙铁辉石、钙蔷薇辉石、阳起石、绿帘石，对这些矿物进行电子探针实验，根据得到的分析数据对这些矿物进行归类，通过所得到的主量元素含量，能够有效的判别各矿物类型，对分析矿区蚀变及矿化有重要意义。

The dataset consists of electron probe microanalysis (EPMA) experimental data of minerals collected from the south of Geji Town, western Gangdise Mountains, Qinghai-Tibet Plateau. Regions targeted for elemental content analysis were delineated via observation under plane-polarized light and cross-polarized light using thin sections. After carbon coating treatment, EPMA was conducted to analyze the mineral compositions. The analytical tests were carried out at the Institute of Mineral Resources, Chinese Academy of Geological Sciences. The instrument used was a JEOL JXA-8230 electron probe microanalyzer. The accelerating voltage was set to 15 kV for oxide samples and 20 kV for sulfide samples, with a beam spot diameter of 5 μm. Natural minerals or national standard synthetic metals were employed as reference standards, and the analytical error was less than 0.01%. This study focuses on the main minerals within the ore-forming skarns of the Pb-Zn-Fe-Cu mineralization zone in the study area, including andradite, hedenbergite, bustamite, actinolite, and epidote. EPMA experiments were performed on these minerals, and the obtained analytical data were used to classify the minerals. The major element contents can effectively distinguish different mineral types, which is of great significance for analyzing the alteration and mineralization of the mining area.
