摘要
云南景谷登海山铜矿5个含矿层呈层状贮存于"滇中红层"第三系始新统等黑组紫红色砂岩所夹白色砂岩中,矿石具层纹状原始沉积特征,无明显热液改造痕迹,矿体明显受层位控制,成矿物质主要来源于元谋古陆。结合区域成矿地质背景、矿床地质特征及控矿条件,认为景谷登海山铜矿为砂岩型铜矿床。
Five ore horizons of Denghaishan copper deposit are stored in the purple red sandstone with white sandstone of Tertiary Eocene respectively Denghei formation. The orebodies act like the parabedded forms, lameller and have primordial depositional feature without hydro- thermal modification. The orebody is controlled by the position. The ore-forming material came from the Yuanmou oldland. Based on the the regional ore-forming geological back- ground, geological characteristics of the deposit and prospecting condition, it is considered that the Denghaishan copper deposit belongs to the sandstone type.
