【摘要】：板其磷礦為近年地質(zhì)找礦工作中新發(fā)現(xiàn)的次生磷礦床,礦體產(chǎn)于二疊紀(jì)臺(tái)地邊緣吳家坪組礁灰?guī)r分布區(qū)的古溶洞和第四系殘坡積物中,可再分為溶洞堆積型和風(fēng)化—淋濾殘積型2個(gè)礦床成因亞類。本文根據(jù)普查地質(zhì)報(bào)告第一手資料,在闡述地質(zhì)背景和礦床地質(zhì)特征的基礎(chǔ)上,分析了礦床形成條件,并與美國(guó)田納西州中部的風(fēng)化淋積磷礦床進(jìn)行對(duì)比,建立了該礦床的描述性成礦模式。通過(guò)本次研究,增加了貴州磷礦的新類型,指出了我國(guó)南方溶洞堆積型磷礦床分布的新區(qū)域,為深入研究我國(guó)次生風(fēng)化型磷礦床的形成條件和形成機(jī)制提供了新資料。
[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.
