| 摘 要： | 川西南滇东地区在早寒武世梅树村期处于上扬子浅海环境,沉积一套浅海碳酸盐和磷酸盐。磷矿经历初始沉积和再次富集的成矿作用,与古构造控制的古地理位置密切相关。在川滇潮坪海湾中,由水下隆起分割的三个次级海湾周围的潮下浅滩和潮间带下部为寻找富矿的有利部位。

| Abstract: | The area we debated is in infraneritic environment at the Meishucunian Age,early Cambrian Period,when deposited a suit of carbonate and phosphate. After initial sediment and consequent concentration,the formation of the phosphorite is related closely to the paleogeography. It is suggested that,in the tidal flat gulf,there is a very good prospecting perspective in undertidal bank and in the bottom of intertidal zone. |
