本文把苏联各地区从早元古代堆积起来的沉积岩层的厚度与锡矿化的相对含矿性进行了对比。查明:含矿程度随沉积旋回的增加而急剧增加。从而证明,在地槽构造中心部分,含锡程度的增加是一个规律。
This paper compares the thickness of sedimentary rocks accumulated in all areas of the Soviet Union from the Early Proterozoic with the relative mineralization of tin mineralization. It is ascertained that the degree of ore-bearing increases sharply with the increase of sedimentary cycle. Thus, it is proved that the increase of the tin content is a regularity in the central part of the earth-trough structure.
