广西扶绥县渠旧矿区熔剂用石灰岩矿地质特征及矿床成因

Geological Characteristics and Genesis of Limestone for Flux in Qujiu Mining Area,Fusui County,Guangxi

渠旧熔剂用石灰岩矿位于扶绥县渠旧镇,为一大型熔剂用石灰岩矿。矿床赋存于上石炭统—下二叠统马平组中,岩性为灰、灰白色厚层块状微晶生物屑灰岩及生物屑灰岩,矿石质量良好。查明该矿床出露的地质特征及成因,为区内后续石灰岩找矿工作提供参考。分析矿床成矿地质条件及沉积环境特征,认为渠旧熔剂用石灰岩矿为浅海开阔台地相化学或生物化学沉积矿床。

Qujiu Limestone Mine for Flux is located in Qujiu Town,Fusui County.It is a large-scale limestone mine for flux.The deposit occurs in the Upper Carboniferous-Lower Permian Maping Formation.The lithology is gray,gray-white thick layered massive microcrystalline bioclastic limestone and bioclastic limestone,and the ore quality is good.Find out the geological features and genesis of the deposit,which provides reference for the follow-up limestone prospecting work in the area.By analyzing the ore-forming geological conditions and sedimentary environment characteristics of the deposit,it is believed that the limestone mine for flux in Qujiu is a shallow sea open platform chemical or biochemical sedimentary deposit.
