| 摘 要： | 通过在西昆仑黑恰—三十里营房地区开展1∶5万水系沉积物扫面、大比例尺矿产地质填图、地质-物探-化探综合剖面测量及槽探等工作,在查明地质特征、成矿类型及成矿规律的基础上,评价该区矿产资源潜力。结果表明: 研究区主要有黑恰海底喷流沉积(改造)型铁多金属矿、阿克塔河南海相沉积型含钛铁矿及阿克塔河北层控型铜金矿3种成矿类型; 划分了7处成矿预测区,其中A类预测区1个,B类预测区1个,C类预测区5个; 铁矿石预测资源量为1 565.69万t,锰矿石预测资源量为39.73万t,铜金属预测资源量为0.35万t,铅金属预测资源量为1.33万t,锌金属预测资源量为2.58万t,钛金属预测资源量为14.76万t; 圈定了5处找矿靶区,其中A类找矿靶区2处,B类找矿靶区3处; 建议进一步对黑恰铁多金属成矿带开展Fe、Pb、Zn找矿工作,扩大找矿成果; 首次在阿克塔河南早石炭世帕斯群发现海相沉积型含钛铁矿矿体,有望取得重大找矿突破。

| Abstract: | According to the 1∶50,000 stream sediments survey, large scale mineral geological mapping, geochemical comprehensive profile and exploratory trench in Heiqia to Sanshiliyingfang areas of West Kunlun, the authors evaluated the prospecting potential based on the geological characteristics of minerals, metallogenic types and prospecting rules in this region.The research indicates that there are three main types of deposits in this area: submarine exhalative-sedimentation (remold) type iron polymetallic ore in Heqia sea, marine sedimentary type of iron ore containing titanium in southern Atake river and stratum-controlled copper gold mine in northern Atake river. Seven metallogenic prediction regions were identified, including one class A, one class B, and five class C areas. The estimated resources were 15.656 9 million tons of iron ore, 0.397 3 million tons of manganese ore, 3.5 thousand tons of copper, 13.3 thousand tons of lead metal, 25.8 thousand tons of zinc and 0.147 6 million tons of titanium. Five prospecting target areas were further delineated, including two class A and three class B target areas. The authors also suggested that priority should be given to the prospecting work of Fe, Pb and Zn in the iron polymetallic mineralization belt of Heiqia in order to further expand the prospecting results. This marine sedimentary type iron ore containing titanium was first discovered in Early Carboniferous group, which is expected to achieve significant prospecting breakthrough. |
