摘要:
通过对西藏自治区措勤县德能铜多金属矿的研究发现,矿区内共6条达到工业品位的铜矿体,并伴生有铅、锌、金、银等多种有益组分,成矿地质条件较好。矿体主要赋存于燕山期石英闪长玢岩岩体外接触带及构造破碎带中,其中Cu4矿体规模最大,经深部钻孔工程及地表槽探验证,矿体品位和厚度沿走向和倾向变化系数较小。燕山晚期第一阶段第一次石英闪长玢岩侵入体是主要成矿物质来源,后期北西西向断裂构造是主要导矿和容矿构造。
Abstract:
The study of Deneng copper-polymetallic deposit in Coqen county,Tibet,shows that in the mineral district there are six ore bodies copper ore with productiongrade of Cu,associated useful components of Pb,Zn,Au,Ag,etc.and good ore-forming geological conditions.The ore bodies are mainly occured in the exocontact zones of Yanshanian guarts diorite porphyrite intrusions and tectonic fracture zones,among them,Cu4 ore body is the largest one.The deep drilling and surface trenching show that the variation coefficients of ore grade and thickness along the strike and tendency of ore bodies are small.The quartz diorite porphyrite intrusions of the first time of the first stage late Yanshanian are the main source of ore-forming materials,the late NWW-trending faults are the main ore channels and host structures.
