新疆塔什库尔干县赞坎铁矿外围水系沉积物地球化学特征及找矿方向

Geochemical characteristics of stream sediments and prospecting orientation in the periphery of the Zankan iron ore deposit, Taxkorgan, Xinjiang

通过塔什库尔干县赞坎铁矿外围地区水系沉积物地球化学特征及其元素相关性的研究表明,元素(地球化学)异常(高值区)严格受塔阿西-色克布拉克断裂带,以及泥盆纪地层、热液活动、岩脉等因素联合控制。根据异常特征与成矿地质条件,圈定了4处成矿远景区,即赞格尔铅银钨多金属成矿远景区(Ⅰ_1)、西若钨锡钼铜多金属成矿远景区(Ⅱ_2)、盖家克铬镍铜金多金属成矿远景区(Ⅱ_3)和哈尼沙里地金多金属成矿远景区(Ⅱ_4),为下一步找矿工作指明了方向。

In this paper, the authors report the geochemical prospecting results around the margins of the Zankan iron deposit and discussed the relationship between elements as well as their coupling with the regional geology. Studies reveal that the geochemical anomalies are obviously constrained by the Taaxi-Sekebulake fault, the lithology of Devonian strata and the igneous activities. According to the features of the geochemical anomalies, in combination with regional geology, the authors delineated four ore prospecting areas, i.e., the Zanger Pb-Ag-W prospective area, the Xinuo W-Sn polymetallic prospective area, the Gaijiake Cr-Ni-Cu prospecting area, and the Halishali Au polymetallic prospective area. The results point out the prospecting locations in the feature.
