摘　　要：海泡石用途广泛。在我国境内已有 13个省 (区 )发现这一矿产。赣、湘、苏、陕等地海泡石占全国已知海泡石储量的 80 %以上。海泡石矿床多产于地台沉积坳陷带边缘 ,成矿时代主要为二叠纪和第三纪 ,矿床分为沉积型 (陆相沉积、海相沉积、火山沉积 )Sepiolite deposits having high value in use have been located in 13 provinces (autonomous regions) of China. Among them, Jiangxi, Hunan, Jiangsu and Shaanxi provinces have sepiolite reserves making up more than 80% of the total reserves in the country. Generally, they generally rest on margins of platform depressions and formed essentially in Permian and Triassic periods. Deposit types may be classified into two main sorts, sedimentary (continental, marine and volcanic-sedimentary) and hydrothermal.
