近年来,关于内生矿床有规律地赋存在地槽发育的某一阶段的成矿概念(毕里宾,1955),受到了明显的修改.按照个别发育阶段的表现程度和成矿特征划分出不同类型的地槽、成矿省及活动带(斯米尔诺夫,谢苗诺夫等人,谢尔巴),突出了独立活化区和中间地块重要的成矿意义(谢格洛夫).为了进一步确立成矿和成矿规律理论,在国内外一些研究人员的著述中发展起来的崭新的大地构造概念引人注目.关于扩展的大洋底和大陆生长机理的认识,得到了贡瓦
In recent years, the concept of mineralization (Biribin, 1955), which has been regularly assigned to some stage of geosynclinal development in endogenic deposits, has been significantly modified, and is divided according to the degree of individual development and the characteristics of mineralization Different kinds of trenches, mineralization provinces and activity belts (Smirnov, Semenov et al., Sherba) highlight the important metallogenic significance of the independent activation zone and the middle block (Segalov) In order to further establish the law of mineralization and mineralization, a brand new concept of tectonics developed in the writings of some researchers both at home and abroad is drawing attention. The understanding of the extended ocean floor and the growth mechanism of the continent has given rise to
