中国-老挝古近纪钾盐矿对比

CORRELATION BETWEEN PALAEOGENE K-SALT DEPOSITS OF CHINA AND LAOS

云南江城勐野井钾盐矿的探明,填补了我国无固体钾盐矿的史例。时代属古近系古新统(E1),与老挝万象钾镁盐矿属同时代、同构造带。勐野井钾盐矿赋存在勐野井组上部(E1m e3),属氯化钾(KC l)类;老挝万象钾镁盐矿属光卤石类,地层为古新统塔贡组下部(E1tg1)。

The exploration of Mengyejing K-salt deposit in Jiangcheng of Yunnan has changed the history of China without solid K-salt deposit. The age of this K-salt deposit belongs to Palaeogene Palaeocene （N1）, which is formed in the same period and in the same structual Zone as those of Vientiane K-Mg salt deposit of Laos. The Mengyejing K-sah deposit takes place in the upper part of Mengyejing Formation （E1me^3）, which belongs to the KCl type. The Vientiane K-Mg salt deposit of Laos takes place in the lower part of Thagong Formation （E1tg^1） and belongs to the camallite type.
