摘要
本文根据１９８７、１９９１和１９９２年１２０个钻孔剖面岩性资料得出，察尔汗盐湖首采区及其附近地区上岩层中光卤石主要分布在首采区范围内，首采区外的东部、北部和东南部亦有少量分布．其分布井段一般为埋深３～１０ｍ．光卤石主要分布在中细粒致密（或松散）和含粉砂中粗粒松散石盐层中，多呈散状或似层状分布；在碎屑层中亦有少量光卤石分布．并对光卤石成因和沉积演化进行了初步讨论．
Carnallite distributes mainly in the first mining area. with a small amount in the eastern.northern, and southeastern ports off the first mining area. The core section of the carnallite distribution ranges from 3 to 10 meters in depth. Carnallite distributes mainly in the compact (or loose) halite bed or the salt-bearing middle-coarse grain halite bed. Carnallite distributes in a small amount in the elastic bed. Carnallite in salt bed is basically of authigenic origin and is a secondary origin too.
