中文摘要: |
内蒙古白云山镍多金属矿空间分布受控于红柳河—洗肠井早古生代蛇绿构造混杂岩带,属与基性—超基性岩有关的铜镍硫化物型。通过前期工作发现,该矿的主要控制因素为构造、蛇绿岩和碳酸盐岩层位,综合分析认为:以“基性—超基性杂岩体+高磁、中高极化、高重力、中低电阻+Co、Ni、Cu综合化探异常+蛇纹石化、孔雀石化、滑石化”为核心的矿床综合信息找矿模型是蛇绿构造混杂岩带内寻找镍多金属矿行之有效的手段。认为对镍钴(铜)矿化蚀变带应加强有关构造、岩相分带及成矿机理的研究,寻找富厚矿体。 |
英文摘要: |
The spatial distribution of the Baiyunshan nickel polymetallic deposit is controlled by the Hongliuhe - Xichangjing tectonic hybrid belt, the deposit is a sulphide type copper-nickel deposit related to the basic and ultrabasic magma. Based on the previous work, it was found that the main ore-controlling factors are geological structures, ophiolite rocks and the carbonate strata. The integrated analysis indicates that the core of the exploration model established on comprehensive information is the basic- ultrabasic complex rock body with high magnetic anomaly, medium-high polarizability, high gravity, low-medium resistivity geophysical anomalies and geochemical composite anomalies of Co, Ni and Cu elements, and alterations of serpentinization,malachite and talcization is the effective prospecting approach for exploring the nickel polymetallic deposit in the Hongliuhe-Xichangjing tectonic hybrid belt. Finally it is suggested that the structures,zoning of lithological phase and metallogenic mechanism should be focused for finding the thick and high grade nickel orebodies in the practical exploration. |
