新疆喀喇昆仑地区俘虏沟南大型伟晶岩型锂矿成矿地质特征及找矿远景

Metallogenic geological characteristics and prospecting of the large pegmatite-type lithium deposit in the south of Fulugou, Karakoram

摘要

摘要:
研究目的 近年来，新疆喀喇昆仑地区伟晶岩型稀有金属矿产找矿工作取得了一系列重大突破，如何在现有基础上取得更大找矿突破成为业内关注重点。
研究方法 综合运用野外地表调查、深部钻探验证、系统取样、室内化验分析等手段开展找矿工作，并结合区域地球化学特征，对俘虏沟南一带及其外围找矿远景进行分析研究。
研究结果 圈定11条锂矿体，Li₂O平均品位1.32%~1.89%，矿体长240~760 m，厚2.22~8.61 m，赋存于三叠系巴颜喀拉山群中，呈NWW—SEE走向，局部EW走向，倾向N—NE，倾角45°~60°，预测资源量大。
结论俘虏沟南一带及其外围Li元素地球化学异常明显，区域锂矿资源禀赋优越，找矿前景良好，可作为新疆稀有金属矿产资源找矿勘查的重点区域。

Abstract:
Objective In recent years, a series of major breakthroughs have been made in the prospecting of rare metal minerals in pegmatite type in the Karakoram region of Xinjiang. How to achieve greater breakthroughs in mineral exploration on the existing basis has become a focal point of attention within the industry.
Methods Comprehensive geological prospecting work was carried out by using the methods of field geomorphological survey, deep drilling verification, systematic sampling and indoor chemical analysis, the prospecting prospects of the southern section of Fulugou and its surrounding areas were analyzed and studied in combination with the characteristics of regional geochemistry.
Results 11 lithium ore bodies were delineated with an average Li₂O grade of 1.32%~1.89%, a length of 240~760 m, a thickness of 2.22~8.61 m, and are hosted in the Triassic Bayan Mountains Group, with a strike of NWW—SEE and a local EW strike, a dip of N—NE, and an inclination of 45°~60°, and the estimated industrial ore resources of Li₂O are height.
Conclusions The south of Fulugou and its periphery show obvious geochemical anomalies of Li element, the regional lithium resource endowment is superior, the prospecting is good, and it can be used as a key area for the prospecting and exploration of rare metal mineral resources in Xinjiang.
