一、言前各种矿产皆是地质历史发展中的产物,它们是与沉积层的发展,构造运动和岩浆活动分不开的,也就是锐各种矿产的形成和分布的规律皆为大地构造所控制。在展开大规模普查勘探以及加强地质矿产研究的今天,对于各地区的大地构造的研究及单元的划分,是为当前地质工作者的迫切要求。目前对大地构造单元方面,由于各家观点上和方 First, before the words all kinds of minerals are the product of geological history, they are with the sedimentary development, tectonic movement and magmatic activity are inseparable, that is sharp all kinds of mineral formation and distribution of the law are all the earth structure Controlled. Nowadays, large-scale census exploration and geology and mineral research are intensified. The research on geotectonics and the division of units in various regions are urgent requirements for current geologists. Currently on the tectonic unit, due to various viewpoints and parties
