| 摘 要： | 中国硅藻土矿床主要赋存于地洼余动期亚构造层中；在空间上主要分布在我国东部华夏期地洼区和西南部中亚期地洼区。根据游离SiO2来源及成矿作用特征，可划分出火山沉积型及陆源沉积型等两种矿床成因类型。通过成矿大地构造条件分析发现地洼余动期最有利于硅藻土矿床的形成。

GEOLOGICAL CHARACTERISTICS AND TECTONO-METALLOGENIC CONDITION OF DIATOMITE DEPOSITS OF CHINA |
| |
| Abstract: | Diatomite deposits distributed over the Cathaysian diwa regions in eastern China and theMid-Asian diwa regions in Southwestern China occur in the sub-structural layer withresidual-mobility period of diwa. They can be subdivided into two types: the vocanosedimentation and the terrigenous deposit, according to the source of dissociative silicon andmetallogenic characteristics. Residual-mobility period of diwa is .the most favourable periodof mineralization. |
