摘要
庐枞火山岩盆地是长江中下游地区一个重要的铁、硫、铜、铅、锌、明矾石、高岭土等矿产地之一。为解决本区高岭土矿的找矿方向问题,在收集以往地质资料的基础上,结合地质测量、岩矿测试等手段对刘家凹高岭土矿床进行综合分析研究,研究结果表明矿床成因类型为热液蚀变型和风化型;矿石自然类型为硬质高岭土和软质高岭土;高岭土矿床的形成受原岩性质、火山热液活动、构造活动、侵入岩、风化淋滤等因素控制,同时认为庐枞火山岩盆地东北部地区高岭土成矿地质条件好,具有进一步的找矿远景。
The Luzong volcanic basin is an important mineral production area which gets iron,sulfur,copper,lead,zinc,alunite,kaolin and other minerals.In order to solve the prospecting direction of the kaolin ores in this area,based on the past geological data collection,and combined with the geological survey,rock and mineral analysis and so on,in view of a series of comprehensive analysis and research of Liu Jiaao kaolin deposits.The result are as follows：the genetic type of the deposit is hydrothermal alteration and weathering type;ore natural type for the hard and soft kaolin;kaolin deposit formation is controlled by the original rock properties,volcanic hydrothermal activities,tectonic activities,intrusive rocks,weathering and leaching factors and so on;kaolin ore forming geological condition in the northeast area of the Luzong volcanic basin is superior and has further ore-prospecting.
