海泡石-坡缕石粘土矿物族,又通称为海泡石族,属链-层状硅酸盐,比起别的主要粘土(?)物来。它们很少引起人们的重视。其原因之一就在于它们比别的层状硅酸盐要少得多,其次是过去难于准确鉴别。尽管如此,近年海泡石和坡缕石颇有名气,因为它们具有一系列有别于其他粘土矿物的极其有用的物化性能,有着广泛的工业用途,国际市场价格逐年上涨。海泡石-坡缕石的成因大体分为两类,一是热液蚀变产物,常呈“石棉”状、脉状产出, Sepiolite - palygorskite mineral group, also known as the sepiolite family, is a chain - layered silicate, compared to other major clay (?) Objects. They seldom attract people’s attention. One of the reasons is that they are much less than other layered silicates, followed by the past is difficult to accurately identify. In spite of this, sepiolite and palygorskite have gained some popularity in recent years because of their extremely useful physico-chemical properties, which are distinguished from other clay minerals, have a wide range of industrial uses and their prices in the international market have risen year by year. The cause of sepiolite - palygorskite can be divided into two types: one is hydrothermal alteration product, often “asbestos”
