中文摘要: 研究区位于东南亚锡铁成矿带中心部位,锡铁多金属矿资源丰富,找矿潜力较大。笔者利用地质填图、槽探、岩矿测试等手段对区内新发现的两条锡铁矿体进行了评价,认为矿体规模大,矿石品级好。矿体产于花岗岩外接触带石炭系上统空树河组第三岩段碎屑岩中,前寒武纪变质岩群和燕山中早期明光-勐连岩带白垩纪花岗岩体为主成矿母岩;成矿受富锡地层和后期富锡花岗岩岩浆侵入作用及南北向控矿构造F14的共同制约;矿床类型为锡石硫化物脉型锡铁多金属矿;成矿期为燕山中晚期-喜马拉雅早期。本文对中缅边境地区锡铁多金属矿风险勘查具有指导作用。
Abstract:The study area is located in the center of the tin-iron metallogenic belt in Southeast Asia, tin- iron polymetallic ore resources rich, prospecting potential. By means of geological mapping, trough exploration and rock ore testing, the author evaluates the two newly discovered tin ore bodies in the area, and concludes that the ore bodies are large in scale and the ore grades are good. The ore body occurs in the clastic rock of the third member of the upper carboniferous Kongshuhe formation in the outer contact zone of granite. The precambrian metamorphic rocks and the gretaceous granite in the middle and early Mingguang-Menglian rock belt of Yanshan are the main metallogenic parent rocks; The mineralization is restricted by the intrusion of stanni-rich stratum and late stanni-rich granite and the south-north ore-controlling structure F14; The deposit type is cassiterite sulfide vein type stannum iron polymetallic ore; The metallogenic period is the middle and late Yanshanian-early Himalayan period. This paper is instructive for the risk exploration of tin-iron polymetallic ore on the border between China and Myanmar.
