摘要
利用金川铜镍矿Ⅱ矿区试验性化探研究成果,主要分析了Cu、Ni主成矿元素的地表原生晕异常分布特征和地表Cu、Ni含量与深部铜、镍矿化强度的关系及变化,初步认为:①Ⅱ矿区地表Cu、Ni元素平均含量与深部铜、镍矿体的平均品位存在较好的空间分布一致性,利用其特点可大致了解深部矿化的强度和空间变化;②构造地化剖面调查可以获得某些与超基性岩矿化有关的构造地球化学信息。
Based on the geochemical results of experimental study in Ⅱ mine district of Jinchuan Cu-Ni deposit, the anomalies distribution of surface primary halo, relationships and varations between the contents of Cu and Ni in the surface and the intensity of metallization in the deep are analyzed. Such views are put forward as： 1） it exits the good consistency of distribution in space between the contents of Cu and Ni in the surface and the average tenor of Cu-Ni ore-body of mine district, this consistency can be used to understand roughly the intensity of metallization in the deep and variation in space; 2） the survey of geochemical structural section will provide the geochemical information related to the metallization of uhrabasic rock.
