摘要：册亨板其磷矿是近年地质找矿工作中新发现的磷矿床,矿体主要产出于贵州西南部右江盆地二叠纪孤立碳酸盐岩台地边缘相吴家坪组(P3w)礁灰岩分布区的古溶洞中。地质普查工作圈定了5个矿体,矿床规模为小型。通过对矿床地质特征初步研究表明,该矿床属次生风化淋滤溶洞堆积型磷矿床,可进一步划分为风化-淋积型和残坡积型2个成因亚类。该矿床的发现和普查地质成果充分证实,在特定的风化条件下,富含磷质的灰岩可以直接风化形成具有一定经济价值的磷矿床。该研究结果为贵州乃至我国南方碳酸盐岩分布区的风化型磷矿找矿工作提供了新资料和新线索,指出了新的找矿区域或方向。
The Banqi phosphate deposit has been discovered recently through geological prospecting in Ceheng County,Guizhou Province.It is located in paleo-krasts in isolated Permain plateform marginal reef limestone,Wujiaping Formation（P3w）of Youjiang Basin area in southwestern Guizhou.A small scale deposit with 5ore-bodies was identified through geological surveys.This preliminary study of the deposit′s characteristics reveals that the deposit is a kind of weathering-leaching krast-accumulated type phosphorite deposits.The deposit can be divided into 2sub-types,i.g.weathering-leaching type and the residual slope type.The new discovery and study results from geological surveys prove that in some special conditions,phosphate-bearing limestone can be weathered directly and become phosphate deposit of commercial value.The results provide direction with new data and research angels in the field of geological investigation in Guizhou Province and southern China.
