中文摘要:
      西南天山成矿带具有较大的资源潜力,区域内矿(床)点星罗棋布,成矿地质条件优越。本次通过1∶5万水系沉积物采集及测量工作系统的分析与研究,查明了新疆柯坪县萨尔干地区喀牧马图幅范围测区元素分布分配特征。在总结地球化学特征后,研究区共圈定了主要的综合异常8处,主要存在2类综合异常,表明研究区内存在2类主要的找矿潜力远景区:分别是以Cr为主,且伴有Co、Ni、Nb等指示元素与基性—碱性杂岩体及基性脉岩有关的镍(铜)及稀有稀土金属矿产预测区,以及以Mo、Hg为主的沉积型+热液改造型钇钨铅锌锰金等多金属矿产预测区。研究表明该地区有良好的找矿前景,可为柯坪地区提供新的找矿方向。
英文摘要:
      The southwest Tianshan metallogenic belt has great resource potential, with scattered ore deposits and superior metallogenic geological conditions. Through the systematic analysis and research of 1∶50000 stream sediment collection and measurement, the distribution characteristics of elements were summarized in the survey area of Kamuma map in Sargan area, Keping County, Xinjiang, and 8 major comprehensive anomalies with 2 types of comprehensive anomalies are delineated in the survey area, indicating that there are 2 types of major prospecting potential prospective areas in the survey area. They are the prediction areas of dominated Cr, accompanied by Co, Ni, Nb, and Ni (Cu) and REE related to basic alkaline complexes and basic dykes, as well as the prediction areas of Y-W-Pb-Zn-Mn-Au and other polymetallic minerals dominated by Mo and Hg hydrothermal reformed deposit. This research shows that there is a good prospecting prospect in this area, and provides a new prospecting direction for the Keping area.
