Geological Characteristics and Prospecting Direction of Caoxi Alkali-making Limestone in Yiyang County,Jiangxi Province
In order to support the demand for mineral raw materials in China's refined high-end alkali industry,deep drilling and surface trenching were carried out in Caoxi mining area to find out the character-istics and spatial distribution of limestone ore bodies for alkali production in the mining area,so as to ana-lyze the genesis of the deposit.By analyzing the exploration results,it is found that the deposit belongs to a stable sedimentary chemical carbonate deposit.The sedimentary environment is in a low-alkali and low-en-ergy shallow open platform environment.The ore-bearing structure is a gentle syncline.The shape and spa-tial distribution of the ore body are distributed with the lower Permian Maping Formation.The high-quality ore is mainly gray thick layered microcrystalline limestone and bioclastic limestone.The petrological charac-teristics are taken as the primary prospecting elements,and the Maping Formation is used as the main pros-pecting marker layer to provide guidance for the prospecting in the Caoxi-Panling area.
