云南下寒武统沉积磷块岩矿床,主要分部于滇东地区,点多面广,其南北延长350公里,东西宽70—130公里,面积达4万平方公里,区内划分为11个磷矿带,已知磷块岩矿区(点)70余个,矿层厚数米至20余米,最大达54.42米,已控制或探明了大量的工业储量,并具有巨大的潜在资源远景。本文就近年来野外工作所获资料,拟对云南下寒武统磷矿地质若干问题试行探讨,不妥处,请指证。 The Lower Cambrian phosphorite deposit in Yunnan Province is mainly distributed in eastern Yunnan with a wide range of points. Its north-south extension is 350 km and the east-west width is 70-130 km with an area of ​​40,000 km 2. The area is divided into 11 phosphorus There are more than 70 phosphate rock blocks (spots) in the ore belt. The ore thickness is more than 20 meters and the maximum is 54.42 meters. It has controlled or proved a large amount of industrial reserves and has a huge potential resource prospect. In this paper, field work in recent years, the information obtained, to be on the Lower Cambrian phosphorite geology in Yunnan a number of issues probed, not proper, please indicate.
