一、引言及符号进行物理作用的空间范围称为场。地球空间中某物质系某相中某组分进行扩散时受到了扩散作用力,呈该性质的地球空间范围称为地球化学位场或扩散作用力场。本文从上述观点出发,以单一组分组成的理想气体为模型,应用了作者建议的光子原理化学热力学方法, 相似文献

Some typical examples illustrating the tenor contraction of such metallic ore veins or bodies as Au, Pb, Zn, W, Sn, Ta and Nb have been recorded by Chinese geologists in the course of ore exploration and mining. The similar demonstrations have also been observed in Japan, Peru and the U.S.S.R. by their respective geologists. Yet its origin as a problem in the field of ore deposits remains unsolved. In this paper, by adopting the photon-based chemical thermodynamical method proposed by the author, the gravitational field position Z related to the intensity of the diffusion force of ore fluids are proved to be the leading factor causing the tenor contraction of metallic veins or bodies. The tenor contraction of metallic veins or bodies under suitable ore-controlling structural conditions is an objective fact in the science of ore deposits, though in no case should it be regarded as a rule to deny the necessity of searching for ore at depth. The variation of the deep-seated ore-controlling structures might alter the tenor of the metallic veins or bodies. The Taipushi wolframite deposits in Nei Monggol could be taken as a convincing example. The tungsten content increases at great depth owin,g to the dilatation during ore deposition along the schistosity of the Proterozoic crystalline schists. There also have been observed similar phenomena in other deposits of China. 相似文献

内蒙古结胜盘大型铅锌多金属矿床是在1979年通过地质、物化探综合找矿方法发现的，是继五十年代发现白云鄂博大型铁-稀土矿床和霍各气、炭窑口，东开庙大型铜多金属矿床之后又一种类型的铅锌多金属矿床。 相似文献

我国找矿勘探及开采工作实践证明,一些金、铅、锌、钨、锡、钽、铌等金属矿脉(体)品位的垂直分布具收缩性质。国外一些同类矿床及铜、铀矿体(脉)亦呈同样性质。上述矿床的这一地质现象已经引起了地质工作者的注意,曾进行了描述或说明,但迄今未能查明其成因,本文拟阐明其成因。 相似文献
