| 摘 要： | 江西省弋阳县大源岭瓷石矿是2009年江西省发现的重要矿产地之一。通过对矿区地质特征、矿体特征分析研究,大源岭瓷石矿为赋存侏罗系于林山组层间裂隙的岩浆侵入矿床,矿体厚度大、规模大、储量大,矿体与围岩接触界线清晰,容易辨认。通过对矿石特征以及加工技术性能的分析研究,瓷石矿石为绢云母化微细粒少斑花岗斑岩,三氧化二铝等粘土矿物含量高,铁主要以菱铁矿赋存,矿石质量好,为优质瓷石。矿石工业类型属硬质瓷石,矿床成因为岩浆自变质矿床。该矿床的发现不仅为江西省陶瓷产业发展提供了资源保障,而且为今后江西省乃至全国寻找同类型瓷石矿床有重要的现实指导意义。

| Abstract: | The Dayuanling chinastone mine in Yiyang,Jiangxi province,is a significant mineral deposit discovered in 2009.Analysis of the geology and orebody characteristics in the mining district reveals that Dayuanling is a magma-intrusion deposit hosted in interlayer fissures of the Jurassic Linshan Formation.Chinastone orebodies formed therein are thick,voluminous,and of considerable reserves.Distinct contact with country rocks makes the orebodies easy to discern.Based on a study of the orebody characteristics and ... |
