贵州开阳北部地区陡山沱期磷矿成矿远景预测
Prediction of the ore-forming prospects of the Doushantuo period phosphate deposit in the north of Kaiyang county,Guizhou,China
摘要
Abstract
Kaiyang area in Guizhou Province is an important mineralization area for the Doushantuo period phosphate deposits,with developed rich phosphate deposits accounting for about 66%of China's rich phosphate deposits.Through comprehensive analysis of regional geology,sedimentary sequences of phosphate bearing rock series,lithofa-cies paleogeography,and ocean current direction,it is believed that the Doushantuo period in the northern part of Kaiyang is a development area of subtidal intertidal zone intertidal zone.The phosphorus rich seawater in the upwelling ocean current precipitates in this environment,which has good conditions for phosphate mineralization.Based on this,five mineralization prediction prospect areas,namely Nanmudu,Wengjiaba,Majiahe,Zhongping,and Miping,have been delineated.These areas may have medium to large and super large phosphate deposits.关键词
