| Abstract (English): |
In the new round of strategic breakthrough in mineral prospecting, critical mineral resources, such as Ni, Cu, PGE, W, Sn and Mo, are mainly produced in the small intrusions and/or their adjacent country rocks. The mechanism of “small intrusive mineralization” was systematically explained; the main scientific issues of the theoretical system, such as the characteristics of the source and the evolution process of the ore-forming magma and/or hydrothermal fluid, the mass balance of the ore-bearing intrusion, and the emplacement depth, uplift height, erosion degree of the ore deposits, were discussed. By introducing examples of mineral prospecting breakthroughs guided by the theory of “small intrusive mineralization”, a three-step evaluation method for mafic-ultramafic intrusion was proposed to screen out the ore-bearing intrusion quickly and economically by grasping the key information elements from a variety of geology, geophysics, geochemistry, and remote sensing imagery. Exploration results to date indicate that the theory of “small intrusive mineralization” has enormous prospective potential. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): |
镍、铜、铂族、钨、锡、钼等关键矿产主要产于小岩体和/或附近的围岩中。系统阐述了小岩体成(大)矿的机制,并以岩浆型Cu-Ni-PGE硫化物矿床为例,总结成矿理论的主要科学问题; 依据小岩体成(大)矿理论指导找矿突破实例,针对镁铁—超镁铁质岩体,从地质、物探、化探、遥感等信息中总结成矿要素,提出了快速筛选含矿岩体的评价方法。大量勘查成果表明:小岩体成(大)矿理论对地质找矿具有重要指导意义。 [ABSTRACT FROM AUTHOR] |
