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。
The Banqi secondary phosphate deposit was found through geological prospecting recently. Ore-bodies exist in ancient caves and Quaternary residual deposits from platform edge of Permian Wujiaping Formation reef limestone. Besides, they can be subdivided into caves 2 genetic sub-types, accumulation types and weathering-leaching residue type. Based on primary data from geological investigation report, in this paper the geological background and ore-deposit characteristics were described and the ore forming conditions were also discussed. Meantime, descriptive ore forming model was established as well. By contrasting with the phosphate deposits from central Tennessee in USA, a new type phosphate deposit was proposed in the research. A new distribution area of caves accumulation type phosphate deposits was pointed out in the Southern China and some new data were provided for further studies on ore forming conditions and its mechanism of secondary phosphate deposits in the Southern China.
