摘要
基于地球内核旋转产生地球电场和磁场的同时可使深部物质上涌 ,地球环境电磁场应与成矿作用间存在某种联系 ,故笔者设想地球电、磁力可能对成矿作用有一定的控制性。地球深部电场力和浅部磁场力能使导电矿物和磁性矿物发生分离或聚集 ,是地壳深部巨量矿质预富集的重要形成过程 ,该过程与地壳大型超大型矿床的形成必有一定的内在关系。根据金和黄铁矿等本身所通过的电流来描述它们周围的磁场、相互作用力的大小和含金流体的性质 ,铁磁性矿物巨量富集与磁引力的关系 ,抗磁性有色多金属矿物巨量富集与磁斥力关系的讨论等 ,都表明地球电、磁力对成矿作用控制的可能联系。这种可能联系对中国东部中生代成矿的解释上充分显示出地球磁力。
The Earth's inner core circumvolving comes into being electric-magneticmagnetic field and has deep substance gushing at the same time,which increase the connection between environment eletric-magnetic field and metallogenesis The authors put forward that electric force and magnetic force in the earth are likely to control metallogenesis in some degree Deep electric field and shallow magnetic field in the earth are able to separate or concentrate the conductive minerals and magnetic minerals It is an important process that there are jillion useful minerals beforehand enriching in the Earth's crust deep The process must have had a definite internal connection with large and super large ore deposits forming in the Earth's crust On the basis of discussing of surrounding magnetic field described by gold and pyrite of electric current pass,and its intensity of interaction and character of Au-bearing,fluid,as well as the possible connection between jillion enriching ferromagenetism mineral and magnetic attractive force,and of the possible connection between jillion enriching repelling magnetism mineral and magnetic repulsive force,indicate the possible connection of the earth electric force and magnetic force controlling metallogenesis The possible connection entirely reveals the internal matching connection among the earth magnetic force and plate tectonics and Circum-Pacific metallogenetic zone,explaining ore deposits formed in the east of China in Mesozoic era
