Sedimentary Facies of the Cambrian Evaporites in the Upper Yangtze Region and Their Potash-Forming Potential
摘要
Abstract
The Cambrian period is one of the most important potash-forming eras on the Earth. The Siberian Niepa potash deposit that formed in the late Cambrian is one of the largest potash deposits in the world. India and Pakistan also found potash deposits forming in Late Sinian. In Iran are discov- ered potash deposits in the Cambrian System. Contrast to the potash-forming intensity of other continents, the Cambrian period has become a special pot- ash-fomling age in Asia. Recently, more and more Cambrian evaporite basins have been found in China. This study focuses on presentation of the charac- teristics of the upper Yangtze evaporites, and states that there is more than 200 ,O00 km2 evaporite basins in the upper Yangtze area, and delineates two most favorable areas for potash （ sub-basin of gypsum-halite ） ： i.e. the Jiangjin-Luzhou and Jiannan -Pengshui areas. These two areas are good geolog- ic settings for further investigation.关键词
