发布时间：2018-11-07 15:03
【摘要】：板其磷矿为近年地质找矿工作中新发现的次生磷矿床,矿体产于二叠纪台地边缘吴家坪组礁灰岩分布区的古溶洞和第四系残坡积物中,可再分为溶洞堆积型和风化—淋滤残积型2个矿床成因亚类。本文根据普查地质报告第一手资料,在阐述地质背景和矿床地质特征的基础上,分析了矿床形成条件,并与美国田纳西州中部的风化淋积磷矿床进行对比,建立了该矿床的描述性成矿模式。通过本次研究,增加了贵州磷矿的新类型,指出了我国南方溶洞堆积型磷矿床分布的新区域,为深入研究我国次生风化型磷矿床的形成条件和形成机制提供了新资料。
[Abstract]:Banqi phosphate deposit is a newly discovered secondary phosphate deposit in recent years. The orebody occurs in paleololvent and Quaternary residual slope deposits in the reef limestone distribution area of Wujiaping formation on the margin of Permian platform. It can be divided into two types: cavern accumulation type and weathering-leaching residual type. Based on the first-hand data of the survey geological report, based on the description of geological background and geological characteristics of the deposit, the forming conditions of the deposit are analyzed and compared with the weathered and leached phosphate deposit in the middle of Tennessee, USA. The descriptive metallogenic model of the deposit is established. Through this study, the new type of Guizhou phosphate ore is added, and a new area of distribution of karst cave accumulative phosphate deposit in southern China is pointed out, which provides new data for further study on the formation conditions and formation mechanism of secondary weathered phosphate deposit in China.
