内蒙古中部地区铜、铅、锌等多金属硫化物矿床综合模型

THE INTEGRATED MODEL FOR Cu, Pb, Zn POLYMETAL SULFIDE DEPOSITS IN THE MIDDLE OF INNER MONGOLLA

本文阐述了内蒙古中部区铜、铅、锌等多金属硫化物矿床综合模型的建立过程.所建模型的抽象式为:碎屑岩与碳酸盐岩交互过渡介质——布格重力异常梯度带——相对稳定磁场背景上的"带状"或"等轴状"磁异常——高极化率、低电阻率异常——Cu、Pb、Zn、As、Cd、Ag、Mn等元素组合的化探异常.最后根据综合模型的组合标志预测了本区的隐伏含矿岩系和隐伏矿床.

This paper presents the established integrated model for Cu, Pb, Zn polymetal mal deposits in the middle of Inner Mongolia ie. alternated clastic rocks and carbonate rocks-gradient zone of Bouguer anomalies-banded and jsometric magnetic anomalies in relative stable magnetic field-higher polarizability and lower resistivity anomalies-Cu, Pb, Zn, As, Cd, Ag, Mn associated geochemical element anomaly zone. Based on the model ore-bearing rock system and blind ore deposit are predicated.
