许多研究者查明,在远东地区一系列锡矿床中汞的含量增高(达n·10~(-3)—n·10~(-2)％),并具有特殊的分带性,汞在锡矿带上部和合矿区域的边缘地段特别聚集。 某些锡矿床内生地球化学晕表明,绝大多数的岩石地球化学样品富含汞,明显地超过克拉克值(达n·10~(-4)％)。 在土尔曼地段,脉状类型的矿床产于上三迭统陆相砂岩页岩沉积物中。除直接与侵入岩
Many researchers have identified a series of tin deposits in the Far East where mercury levels increase (n · 10 -3 -n · 10 -2%) and have a special zonation In the upper part of the tin belt and the edge of the co-ore area, there is a special accumulation. The endogenous geochemical halo of some tin deposits suggests that the vast majority of rock-geochemical samples are mercury-enriched, significantly exceeding the Clarke value (up to n · 10 -4%). In the Turkmen area, vein-type deposits are found in the sediments of the Upper Triassic continental sandstone shale. Except direct and invasive rock
