关于西昆仑地区塔卡铅锌地质特征及找矿探讨

Geological characteristics and prospecting of Taka lead zinc in West Kunlun area

塔卡铅锌矿地处奥依塔格-库尔良裂陷槽偏北方向的区段上,该区具有非常有的铅锌矿成矿背景,区内的矿产资源十分的丰富,成矿地质条件良好,具有很好的铅锌矿成矿条件。塔卡铅锌矿区成矿类型属于密西西比河谷型,其赋矿地质背景、控矿岩石、矿物组合、矿石结构构造、围岩蚀变等,均与典型的密西西比河谷型铅锌矿相似。下石炭统卡拉巴西塔克组第二岩性段白云质灰岩是该矿矿区的主要含矿地层。区内没有突出的岩浆活动特征,基性岩在区内分布非常的上,其产出特征主要呈现层状形态,克孜勒塔格-库斯拉甫断裂偏西方向的区域上发育有大量的岩浆活动特征。文中主要对该矿地质特征进行分析,并对其找矿方向进行探讨,以为区内找矿提供指导。

The Taka lead zinc mine is located in the section of the northern direction of the otag-kurlian fissure trough, which has a very rich metallogenic background of lead and zinc deposits. The mineral resources in the area are very rich, the metallogenic geological conditions are good, and the metallogenic conditions of lead and zinc ores are good. The metallogenic type of the Taka lead-zinc mining area belongs to the Mississippi valley type. Its ore setting background, ore controlling rock, mineral assemblage, ore structure and rock alteration are all similar to the typical Mississippi valley type lead-zinc mines. Dolomitic limestone in the second lithology of the lower Carboniferous Cara Brazil Tucker formation is the main ore bearing stratum in the mine area. There is no prominent magmatic activity in the area, and the basic rock is distributed very well in the area, and its output characteristics are mainly stratiform, and there are a lot of magmatic activity in the region of the west direction of the kiz-Cuse Rahv fault. This paper mainly analyzes the geological characteristics of the mine, and discusses its prospecting direction, so as to provide guidance for prospecting in the area.
