摘要
海泡石有着极其广泛的用途，多产于基本稳定的沉积环境，我国已在13个省区发现这一矿产，赣、湘、苏、秦等地海泡石占全国已知海泡石储量的80％以上，成矿时代主要为二叠纪和第三纪，其矿床分为沉积型和热液型两大类。
The sepiolite deposits have been found in thirteen provinces, in which the content of se-piolite deposits, Located in Gang, Xiang, Su and Qin area, is about 80 percent of total con-tents in China. In this paper, the formation conditions and geological features of sepiolite de-posits are chiefly discussed. At same time, the genetic types of sepiolite deposits are prelimi-nary summarized. It is pointed out that the sepiolite deposits in China are dominated by the marine sedimentary type. The ore bodies mainly occur in Permian and Tertiary periods’ The genetic types include sedimentary type and hydrothermal type.
