运用地球动力作用原理推断黄金埋藏分布规律

本文属探讨性理论文章。从力学观点出发,利用黄金的比重结合各地质年代的地壳强度,运用地球动力原理推断全球黄金埋藏的地理纬度和我国黄金埋藏的特点及部位。文中除分析黄金的力学特性外,重点介绍了地球动力合成作用原理的来源、内容、作用和它与成矿条件的力学关系。提出了4种类型的成矿条件,并以世界金矿资料予以验证。其次还分析了中国地壳受力状态,最后举例说明了我国金矿形成的特点及分布规律。

THE BURIAL AND DISTRIBUTION OF GOLD DEPOSITS AS INFERRED ON THE BASIS OF GEODYNAMIC PRINCIPLE

Based on such properies of gold as stable inertia, great natural specific gravity and the combinatorial ore-forming con-ditions of geodynamics, the author has inferred the burial and distribution of the gold deposits in the earth.Three aspects of the problem are discussed in this paper:1. From the viewpoints, conclusions and formulae of "calculation of rotation force of the earth" and "summarization of earthquake time prediction", the author considers that on every point of the earth act simultaueously four sorts of force, i.e., gravity, rotational pole-fleeing force, revolution inertia force and interstellar gravitational force, which make up the sources of force for crustal movement. According to the distribution of sources of force, the geographic latitude of gold mineral distribution in th whole globe is deuced and tested. Besides, based on the fact that due to the difference in crustal strengths and geodynamic forces, different geologic epochs have diverse geographic locations for gold ore distribution, the author has analysed the relationships of geodynamic action to the conditions and regularity for the formation of gold deposits all over the world.2. The viewpoint of geodynamics is applied to illustrate the relations between gold mineral distribution and global tectonics. Different dynamic forces have resulted in different forms of crustal movement, and thus produced different types of gold deposits, which mainly comprise molten crustal deposit, intru-sive deposits, alteration deposits and placer gold deposits (transported by moving water). The last type also include ore deposits formed for the second time, such as sedimentary-metaniorphic deposits.3. In the light of pole-fleeing force of the rotation of the earth and the pillar rock forces of Indian plate and Pacific plate, the author has analysed the relationships between crustol stress distribution of China, the force state affecting the variations in geomorphologic features and crustal textures, and the crustal movement. On such a basis, the burial characteristics and distribution of gold deposits in China are determined and the faults related to gold mineralization are roughly delineated.
