摘要
西昆仑玛尔坎苏地区晚石炭世优质锰矿找矿取得重大突破,锰矿带层位稳定,厚度较大,品位富,属于典型的海相沉积型锰矿床。笔者通过对成矿地质背景及典型矿床成矿地质特征进行研究,分析控矿地质条件,提出含碳泥晶灰岩、背斜构造、断裂构造、遥感及地球物理等找矿标志,认为玛尔坎苏锰矿带外围及深部找矿潜力巨大,应加强奥尔托喀讷什锰矿床南翼、苏萨尔布拉克、博托彦、托库孜布拉克等的锰矿找矿工作;应重视矿田构造的研究,拓展深部找矿空间;塔里木西缘及北缘石炭系锰矿找矿工作需进一步重视。
A major breakthrough for high quality manganese ore prospecting was made in Maerkansu area, west Kunlun. The manganese ore belt in Maerkansu area is stable with large thickness and rich grade, and the manganese deposits belong to a typical marine sedimentary manganese deposit. In this paper, we study the geological background of mineralization, the geological characteristics of typical deposits and ore-controlling geological conditions. The ore-prospecting criterias were proposed, which include the Carbonaceous micrite, anticline structure, fracture structure, remote sensing and geophysics. It is indicated that there is huge prospecting potential of Maerkansu manganese ore belt. Prospecting work should be reinforced in the south wing of Aoertuokane deposit, Suesalburak, Botuoyan and Tuokuzibulake, and so on. Meanwhile, more attentions should be paid to the study of ore field structure to develop ore prospecting in depth. Prospecting work of Carboniferous manganese deposits in the western and northen margin of Tar-im needs further attentions.
