中国石盐矿床之分类

CLASSIFICATION OF CHINA'S HALITE DEPOSITS

中国石盐矿产资源丰富 ,不同矿床产出地质背景、成矿条件、时空分布特征、物质组成等不尽相同。按其物相特征划分为固相矿床和液相 (卤水 )矿床两大类。前者根据产出时代及岩相特征划分为第四纪盐湖型、中新生代陆相碎屑岩型和前中生代 (含三叠纪 )海相碳酸盐型等矿床类型 ,根据不同的矿石建造还可作进一步划分。后者又可分为不同时代的地表及地下卤水矿床类型。成岩盆地受构造控制明显。有计划地综合开发利用我国盐类矿产资源有重要意义。

China enjoys rich resources of halite minerals. Different deposits are not common with each other in terms of geological setting, metallogenic conditions, space time distribution and mineral paragenesis, but classified into two main deposit types, solid and liquid, according to their physical features. The solid deposits may be further grouped, considering their metalogenic times and lithofacies characters, into such deposit types as Quaternary salt lake,Mesozoic Cenozoic continental clastic and Precenozoic (including Triassic) marine carbonate. There are still alternative division, if according to ore formation. The liquid deposits consist of two subtypes, surface and subsurface brine. Every deposit or salt genetic basin, no matter what type it is, is controlled by geological structures. Tapping in a planned way our resources of salt minerals will be of strategic importance.
