海泡石粘土矿床的成矿地质特征及找矿远景

海泡石矿物特定的结构特征致使其具有较强的热稳定、抗腐蚀、脱色、吸附及抗辐射、隔热、绝缘等优良特性 ,因而是一种具有很大开发应用潜力的矿产。具经济价值的主要为产于二叠纪及第三纪沉积类及火山沉积类矿床。它们形成于相对稳定的构造环境、较干旱的气候 ,偏碱性的介质等条件下 ,热液型矿床则多在中酸性岩浆岩与蚀变白云质大理岩内外接触带产出。海相沉积、火山沉积型及热液型海泡石矿床在我国均具良好的找矿前景

MINEROGENETIC GEOLOGICAL FEATURES OF SEPIOLITE CLAY ORE DEPOSIT AND ITS PROSPECT OF ORE-SEARCH

The specific stractaral features of sepiolite clay mineral make it has stronger hot-stability,anticorrosion,decolour,adsorption,antiradiation,heat insulation,insulation,and so forth fine properties,so that is a kind of mineral resources which there are great potentiality of exploitation and application.Ore deposits which have economical value mainly are depositional type and volcanegenic type produced in the permian period and tertiary period.It formed under the relatively stable structural environmint,drier climate,slantingly alkaline medium and so forth conditions.Hydrothermal pattern of ore deposit commonly produced in the contact zone between mid-adic igneous rock and altered dolomitic marble.Marine facies depositional and volcanic depositional and hydrothermal pattern of sepiolite clay ore deposits are all have good prospect of ore-search in China.
