青海省东昆仑昆中断裂带哈图段地质特征及成矿预测

Characteristics and Metallogenic Predication of Hatu Section in Kunzhong Fault Belt in Eastern Kunlun in Qinghai Province

摘要:

昆中断裂带是东昆仑成矿带发育多条巨型断裂构造之一，控制并切割自元古宙以来的不同地质体，对区域成矿具有明显的控制作用，其次级断裂或主断裂构造的交叉部位往往是成矿通道和容矿部位。研究区位于昆中断裂两侧，属活动区造山带，成矿期次多，类型复杂，具有良好成矿地质条件，已发现矿床、矿（化）点多处，与Nb,Y,La,Cu,Zn,Mo,Au,Ag,As,Pb元素为主的地球化学异常对应较好。

Abstract:

The Kunzhong fault belt is one of the giant fault structure developed in eastern Kunlun ore-forming belt. It controlled and cut different geological bodies since Proterozoic age aong the belt. It has obvious controlling function to regional mineralization. Cross-sites of its secondary faults and main faults are often ore-forming channels and sections. A stream sediment survey with the scale of 1∶50000 and ground high-precision magnetic method survey work with the scale of 1∶50000 have been carried out by Shandong Geophysical and Geochemical Exploration Institue in the studying area. The studying area is located in two sides of KUnshan fault belt, and belongs to active orogenic belt. It has multi-mineralization ages, complex types and good metallogenic geological conditions. Deposits and many mineralization spots have been discovered in this area. It has good anomalies corresponding with many elements, such as Nb, Y, La, of Cu, Zn, Mo, Au, Ag, As and Pb.
