摘要
近几年来吉安县高岭土矿的勘查开发得到迅速发展,发现风化残积型高岭土矿床多处,主要分布在安塘—敖城—官田—浬田一带。通过阐述区内区域地质背景、矿床类型划分及典型矿床特征,总结出高岭土矿矿床控矿因素,提出了区内找矿目标层位为安塘组和水北组,岩性为凝灰质粉砂岩和长石石英砂岩。归纳出区内矿床一般埋藏状态、赋存标高特征、覆盖层特征及分布特征等,共提出了3处找矿远景区。
In recent years,the exploration and development of kaolin deposits in Ji’an County have developed rapidly,and many kaolin deposits have been found.The deposit type is weathering residual type,which is mainly distributed in the Antang-Aocheng-Guantian-Litian area.By expounding the regional geological background,the classification of deposit types and the characteristics of typical deposits area,the ore-controlling factors of kaolin deposits are summarized.It is proposed that the prospecting target horizons in the area are Antang Formation and Shuibei Formation,and the lithology is tuffaceous siltstone and feldspar quartz sandstone.The general burial state,occurrence elevation characteristics,overburden characteristics and distribution characteristics of deposits in the region are summarized,and three prospecting areas are proposed.
