摘要:
通过大量详实的野外地质调查与综合研究, 结合前人的研究成果, 总结出北喜马拉雅东段金锑多金属矿带发育3期成矿作用(同沉积、同碰撞、陆内造山期)和5种矿床类型(喷流沉积-改造型、卡林型-类卡林型、热泉型、次火山岩浆热液型、造山型)。提出控矿“四要素”分布或叠加的地区, 是北喜马拉雅地区最重要的找矿标志。指出羊卓雍错-哲古错被动大陆边缘裂谷(陷)盆地周缘的盆山转换部位是成矿有利部位, 金矿床主要受近EW向拆离构造及其次级构造控制; 锑、金锑多金属矿床主要受近SN向走滑正断系统及其次级构造控制, 特别是EW向拆离系统与SN向走滑正断系统的交汇部位更是寻找锑、金锑多金属矿床的最有利部位。据此划分出3个受近SN向走滑正断层系统控制和2个受EW向拆离构造或韧-脆性剪切构造控制的矿化集中区, 为该带进一步的找矿工作部署与突破指明了方向。
Abstract:
The deposit type and metallogenic age of the gold antimony polymetallic belt in the eastern part of North Himalayan is poorly constrained. Based on the detailed field geological survey and comprehensive studies, together with the previous researches, the authors propose that this belt experienced three pulses of mineralization during the syn-depositional, syn-collisional and intra-continental periods, respectively. We delineate five types of ore deposits including exhalative sedimentation-reworked, Carlin - Carlin-like, hot spring, subvolcano magmatic hydrothermal, and orogenic types, and point out four ore controlling factors. The crossover of the basin and the mountain in the Lake Yamdrok-Lake Zhegu passive continental margin rift valley is the favorable ore-forming area. The gold deposits are mainly controlled by nearly EW-trending detachment structures and the secondary structures; the antimony and antimony polymetallic deposits are mainly controlled by near SN-trending strike-slip normal faults and the corresponding secondary structures. Particularly, the intersection of the two types of structures is the most favorable prospecting area. Furthermore, we argue that the three mineralization districts are controlled by SN-trending strike-slip normal faults and two mineralization districts are controlled by EW-trending detachment structures, which will be helpful for the prospecting deployment.
