新疆托让格库都克地区成矿地质条件与找矿潜力分析
|
摘要
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.
