摘 要: 論述了大地構造、區(qū)域構造、礦區(qū)構造對砂巖型銅、銀礦帶和礦體的控制作用,并以礦帶所處的古地理位置、巖性巖相特點、礦體所處的具體構造 部位、空間產 出狀態(tài)及展布規(guī)律、礦帶中礦體的剝蝕與保留程度、含礦層的物質成分、礦體中金屬 礦物分帶特征等為預測砂巖型銅、銀礦礦區(qū)遠景的依據,將會理紅盆西側劃分出三個成礦帶,即西礦帶、中礦帶和東礦帶,且提出了野外實踐中對上述幾條原則的具體應 用并闡明其找礦前景。

Abstract:Geotectonic structure, regional structure and ore district structure to sandstone copper and silver ore districts and bodies have been expounded. And as the bases of the paleogeograph localization of mineralizing belts, the characteristics of lithologic facies, the ore body distributions in texture, the denudation and residual degree of ore bodies, the compositions of ore-bearing beds, and the zoning characteristics of metallic minerals in ore bodies to predict the potential district about sandstone copper and silver deposit, the authors divided the west Huili red basin into three mineralizing belts: the western, the middle and eastern ones, and suggested the exploratory prospect.
Key words: Kangdian geo-dome diwa basin mineralizing belts opening zoning of metal mineral closing zoning of metal mineral denudation and residual degree
