湘西北吊井岩大理石矿床地质特征及开发应用
|
摘要
吊井岩大理石矿床属海相沉积碳酸盐岩类型,赋存于奥陶系中统牯牛潭组、宝塔组和下统分乡组地层中。矿体成层状,由4个矿层组成,分别产出绿云霞、红绿彩带石、溪州红和龟背石4种大理石品种,其物理性能良好,抗压强度为73.1-99.4 MPa,抗折强度为14.5-24.1 MPa,容重2.66-2.69g/cm~3,吸水率0.26%-0.46%,抗冻性能合格。大理石石质细洁,镜面物像反映清晰,色彩绚丽,古朴典雅,丰富多彩。加工性、装饰性和拼接性良好,是一种优质的饰面石材,开发利用前景良好。
Diaojingyan marble deposits occurs in the Gunitan Formation, BaotaFormation of middle Ordovician and Fen xiang Formation of lower Ordovician. Marine sedimentary carbonate type deposit.Ore bodies occring in layer,is composed of 4 layers,rosyclouds,coloureribbon,xizhoustone,turtle checked respective. physical properties are good, absorbing rate 0.26 %-0.46 %, compressing strength73.1-99.4 MPa,bucking strength 14.5-24.1 MPa,specific weight2.66-2.69 g/cm~3, the satisfaction of antifreezingperformance.Fine texture of marble bright polished face,gorgeous and colourful, beautiful is simplicity, heavy with colour.Theprocessability,ornamenting and piece togegher performance are best, which is of an excellent quality of ornamental stone,showing a vast range of prospecting for exploitation and application.
