中文摘要:
      乐红—茂租地区是滇东北铅锌矿化集中区之一,其矿化普遍、构造特征明显,构造与成矿作用关系密切。典型矿床综合研究表明,该区铅锌矿床成矿地质体为断裂与碎裂白云岩组合,成矿结构面主要有岩性界面和构造成矿结构面,在此基础上建立该区地质成矿模型;并提出以东坪铅锌矿为中心,北西向找矿应注重震旦系灯影组白云岩与寒武系筇竹寺组粉砂质泥岩接触界面部位(茂租式);南东向找矿以产于震旦系灯影组白云岩中北西向断裂破碎带为重点区域(乐红式)。
英文摘要:
      The Lehong-Maozu area is one of the Pb-Zn ore mineralization areas in northeastern Yunnan Province, where the mineralization is widely distributed and ore-controlling structure characteristics is obvious. The structure is closely associated with mineralization. The integrated study on typical lead-zinc deposits indicates that the Pb-Zn mineralization are controlled by both of fractures and cataclastic dolomite. The metallogenic structural planes mainly are lithologic interface and structural planes. The geological prospecting model was set up based on above-mentioned study results. Finally it was proposed that there are two target areas centered in Dongping Pb-Zn deposit should be paid attention in the next stage exploration,i.e., interface between dolomite of Sinian Dengying group and silty mudstone of Cambrian Qiongzhushi group in the northwestern direction (Maozu type), and NW-trending fractured zone within Sinian Dengying group dolomite in the northwestern direction (Lehong type).
