摘要
本文以四川省宁南县银厂沟-骑骡沟地区铅锌矿为研究对象,通过对区域成矿地质背景、构造控矿、地层岩性组合控矿、矿体赋存、稳定同位素、稀土元素、微量元素等进行研究,厘定它们之间的耦合关系,总结银厂沟矿段铅锌矿的成矿规律,建立找矿标志及找矿模型。然后,借助于银厂沟矿段的成矿规律和找矿模型,综合其它矿段的地、化、遥等资料,圈定与银厂沟矿段成矿规律相似的地段(靶区)。最后,概算其余矿段圈定靶区的远景资源量。
     宁南处于扬子板块南部早古生代被动陆缘上近SN向的昆明-昭觉陆架裂陷带的北段,会理-东川拗拉槽北界的天宝山-巧家断裂带附近。银厂沟-骑骡沟地区位于骑骡沟复式背斜西翼,且紧靠背斜轴部。背斜为一区域性背斜,走向近南北,向南倾伏,轴部为元古界会理群通安组地层,两翼由震旦系、寒武系、奥陶系等地层组成。该区出露的主要地层为震旦系和寒武系,次为前震旦系地层及第四系。银厂沟-骑骡沟地区含矿层为震旦系上统灯影组上段(Zbd3),产状215°~245°∠23°~38°,岩性为内碎屑白云岩,由强热液白云石化、密集条带状似碧玉岩化白云岩等组成。区内,未见岩浆岩出露。
     矿石矿物有方铅矿、闪锌矿、黝铜矿、黄铁矿、白铅矿、菱锌矿、车轮矿灯。围岩蚀变主要有硅化、白云石化等。
     银厂沟-骑骡沟地区,主要控矿因素:①地层岩性控矿,由寒武系下统筇竹寺组(?1q)、震旦系上统灯影组(zbd)和观音组(zbg)构成了地球化学梯度变化带,形成良好的储矿系统。②构造及构造组合控矿,顺层剪切构造、张裂断裂、“入”型构造、断裂与横、纵小背斜或小挠曲的交汇处,为主要的容矿部位。③构造演化控制成矿过程具多期多阶段特征。
     通过稳定同位素、稀土元素和微量元素分析,研究区成矿物质与成矿流体具有壳-幔混源特征。均一温度122℃~236℃,属中-低温。矿床类型为具有壳-幔混源特征的浅成中-低温热液铅锌矿床。
     研究区内共圈定18个横向褶皱,和1个由18条剖面构成的纵向褶皱。由横向褶皱和纵向褶皱组合构成的区域为A类远景区,由横向褶皱或纵向褶皱构成的区域为B类远景区。然后,由体积成矿系数法,概算的A类远景区和B类远景区的远景资源量,概算结果分别为13万t、94万t。
Based on the NingNa county of sichuan s Yin Changgou-Qi Luogou as the research object, by regional metallogenic geological background of ore-controlling structure, and lithological association ore-controlling cretaceous. the ore, stable isotopes and trace elements and rare earth elements, etc, they studied the coupling relationship between the silver, and summarizes the lead-zinc deposit metallogenic regularities, establishing ore-prospecting criteria and prospecting model. Then, with the silver of metallogenic regularities of ore prospecting model, and the comprehensive other land, and remote data with Yin Changgou-Qi Luogou, the section of metallogenic regularities of similar area (target). Finally, estimate the rest of ore resource delineating the vision.
     Building in southern Yangtze plate passive continental margin on the early Paleozoic to kunming - nearly SN ZhaoJiao oil-bearing rifting, listens to the north - with depression and the slot dongchuan the days near baoshan - qiaojia fault. The Yin Changgou-Qi Luogou area located on the Qi Luogou ditch west wing, double anticline axis and abuts anticline. As a regional anticline anticline in the near east, west, north and south, to tilt toward the south, the axis of the 0.932 for general Ann formation, two-wing by sinian, Cambrian, yingshan formation, etc. The formation of mainly for sinian and Cambrian, times before the formation and 4 sinian system for.
     The area - the ore-bearing layer is lighted on the sinian section (ec) group, in Zbd3 215°~ 245°∠23°~38°, lithology, clastic dolostone is by hydrothermal dolomitization, dense the ribbon like jasper paleokarstification dolostone, etc. Zone, not seen.
     There ore mineral sphalerite and galena, tetrahedrite, pyrite, white lead, zinc mine, wheel miner's. Wall-rock alteration are mainly dolomitization, etc.
     The Yin Changgou-Qi Luogou area, the main ore-control factors: (1) the lithological ore-controlling, from the Cambrian next series field (?1q )group (ec), the sinian 1q (zbd) and light group avalokitesvara (zbg) constitutes the geochemical gradient belts, forming good store ore systerms. (2) structure and structural combination, ore-controlling structures, strong shear fault, "into" type structure, fracture and horizontal, vertical, or small buckling of small anticline, as the main part of the ore. (3) metallogenic tectonic evolution and controlling process with many characters.
     Through the stable isotopes and trace elements and rare earth elements, study area of ore-forming materials and ore-forming fluid has shell - mixed characteristics. 122°~ 236°uniform temperature, temperature - c. The copper deposit types for shell - mixed with the characteristics of low - the hypabyssal hydrothermal pb-zn deposit.
     Research areas delineated total 18 lateral fold, and 1 by 18 sections of the longitudinal fold. By transverse and longitudinal fold drape of A vision for the region, by lateral fold or longitudinal fold constitute the area for class B vision zone. Then, the volume of metallogenic coefficient method, A kind of vision estimates and class B vision result, the vision of resource estimates 1.3 million ton, 9.4 million ton, respectively.
