东昆仑五龙沟岩金沟金矿床成矿元素分析和黄铁矿热电性数据集
收藏资源简介：
本数据集内容包括东昆仑五龙沟岩金沟金矿床成矿元素分析和黄铁矿热电性数据（主要来自岩金沟金矿床三号矿段）（表1、表2）。成矿元素分析检测委托广州澳实矿物实验室进行。通过火试金电感耦合等离子体发射光谱法（Au-ICP21）和火试金重量法（Au-GRA21）测定金含量，检测范围分别为（0.001-10 g/t）和（0.05-10000 g/t）。通过王水消解法电感耦合等离子体质谱（Hg-MS42）测定汞含量，检测范围为（0.005-100 μg/g），通过四酸消解法电感耦合等离子体质谱（ME-MS61）测定超痕量元素含量。对测得元素进行相关性分析、聚类分析，处理软件为IBM SPSS Statistics22。按照不同标高，从上往下进行采样，选择新鲜有代表性的样品切制成可以用于原位黄铁矿热电性分析的铜薄片，厚度约0.1~0.7mm，薄片上的黄铁矿颗粒保持通透性，保证颗粒在薄片上下两端出露。利用平行移动测笔进行原位点触测试，使用同步影像来观察黄铁矿的解除关系，利用软件跟踪采集相关热电性数据信息。实验在中国地质大学（北京）的矿物标型实验室完成。测试仪器为热电系数测量仪BHTE–08，热端温度设定为125℃，冷端温度为29℃，活化温度控制为95℃左右。该套数据已经发表在国际SCI期刊《Minerals》上（Wu, J.; Zeng, Q.; Wei, Z.;Fan, H.; Yang, K.; Zhang, Z.; Li, X.; Liang, G.; Xia, F. Prospecting Potential of the Yanjingou Gold Deposit in the East Kunlun Orogen, NW China: Evidence from Primary Halo Geochemistry and In Situ Pyrite Thermoelectricity. Minerals 2021, 11, 1117. https://doi.org/10.3390/min11101117），主要成果如下：（1）岩金沟金矿床是富毒砂的蚀变岩型金矿床；（2）元素相关分析和聚类分析表明，Au和As是强相关性元素；（3）原生晕地球化学特征表明矿床为浅部的前缘晕矿体；（4）原位黄铁矿热电数据表明，p型黄铁矿占比约80%，剥蚀率为50%，可推断矿体位置较浅。在此基础上，提出了成矿预测模型。岩金沟金矿床成矿作用好，找矿潜力大，深部至少有一半矿体未发掘，该项研究对深部找矿勘查具有指示意义。
This dataset includes metallogenic element analysis and pyrite thermoelectricity data from the Yanjingou Gold Deposit, Wulonggou area, East Kunlun Orogen (mainly from the No. 3 ore block of the Yanjingou Gold Deposit) (Tables 1 and 2). All metallogenic element analyses were commissioned to Guangzhou Aoshi Mineral Laboratory. Gold contents were determined via fire assay-inductively coupled plasma atomic emission spectrometry (Au-ICP21) and fire assay gravimetry (Au-GRA21), with detection ranges of 0.001–10 g/t and 0.05–10000 g/t, respectively. Mercury contents were measured via aqua regia digestion-inductively coupled plasma mass spectrometry (Hg-MS42), with a detection range of 0.005–100 μg/g. Ultra-trace element contents were determined via four-acid digestion-inductively coupled plasma mass spectrometry (ME-MS61). Correlation analysis and cluster analysis of the measured elements were performed using IBM SPSS Statistics 22. Sampling was conducted from top to bottom along different elevations. Fresh and representative samples were cut into copper thin sections (thickness: ~0.1–0.7 mm) for in-situ pyrite thermoelectricity analysis, where pyrite grains remained permeable and exposed at both upper and lower ends of the sections. In-situ spot testing was carried out using a parallel moving test pen, with synchronous imaging used to observe the contact relationships of pyrite grains, and relevant thermoelectricity data were collected via software tracking. The experiments were conducted at the Mineral Typology Laboratory, China University of Geosciences (Beijing). The testing instrument was a thermoelectric coefficient measuring instrument BHTE-08, with the hot-end temperature set to 125℃, cold-end temperature set to 29℃, and activation temperature controlled at approximately 95℃. This dataset has been published in the international SCI journal *Minerals* (Wu, J.; Zeng, Q.; Wei, Z.; Fan, H.; Yang, K.; Zhang, Z.; Li, X.; Liang, G.; Xia, F. Prospecting Potential of the Yanjingou Gold Deposit in the East Kunlun Orogen, NW China: Evidence from Primary Halo Geochemistry and In Situ Pyrite Thermoelectricity. Minerals 2021, 11, 1117. https://doi.org/10.3390/min11101117), with the main findings as follows: (1) The Yanjingou Gold Deposit is an arsenopyrite-rich altered rock-type gold deposit; (2) Correlation and cluster analyses indicate that Au and As have a strong positive correlation; (3) Primary halo geochemical characteristics suggest that the orebodies are shallow frontal halo orebodies; (4) In-situ pyrite thermoelectricity data show that p-type pyrite accounts for approximately 80%, with a denudation rate of 50%, inferring that the orebodies are relatively shallow. On this basis, a metallogenic prospecting model was proposed. The Yanjingou Gold Deposit has favorable mineralization and great prospecting potential, with at least half of the deep orebodies remaining undiscovered. This study provides significant indications for deep mineral exploration.
