新疆托让格库都克地区成矿地质条件与找矿潜力分析

Mineralization Conditions and Prospecting Potential of Tuoranggekuduke Area in Xinjiang

通过分析托让格库都克地区成矿地质背景和成矿地质条件,认为区内矿产受地层、岩浆岩、构造综合控制,中志留统白山包组、下泥盆统卓木巴斯套组、托让格库都克组、中泥盆统北塔山组和蕴都喀拉组为主要的矿源层;石英闪长岩脉、花岗细晶岩脉和石英岩脉是很好的矿源体;喀斯克尔索汗、库兰喀孜干-博敦等断裂及其次级构造破碎带为含矿气水热液上侵、迁移和成矿元素的富集、沉淀开辟了通道和场所。研究区内划分出2个Ⅰ级成矿远景区和1个Ⅱ级成矿远景区,圈定了五个找矿靶区,为下一步找矿工作指明了方向。

This paper investigated the mineralization backgrounds and mineralization conditions of Tuoranggekuduke Area in Xinjiang. The conclusions include the following： 1） the mine in Tuoranggekuduke area was controlled by the strata,magmatic rocks and structures; 2） the main ore source layer included Baishanbao Formation of Middle Silurian,Zhuomubasitao Formation and Tuoranggekuduke Formation of Lower Devonian,and Beitashan Formation and Yundukala Formation of Middle Devonian; 3） the ore-forming material were sourced form quartz diorite vein,granite aplite vein and quartz vein; 4） the Kasekeersuohan fault,Kulankazigan-Bodun fault and its sub-structural fracture zone provided channels for the invasion and migration of ore-bearing fluid and input places for the enrichment and precipitation of ore-forming elements. Two first-order metallogenic prospect area,one second-order metallogenic prospect area and five prospecting target area were pointed out,which indicated the next ore-founding direction in Tuoranggekuduke area.
