摘　　要：“黟县青”是皖南黟县西递特有的一种地方性工艺建筑石材矿,含矿地层为形成于浅海陆架相环境的寒武系大陈岭组,主要产于蓝田向斜盆地内,为受沉积成因控制的大理岩化灰岩矿床,矿体严格受地层产状控制。黟县青石材矿赋矿岩层为深灰色巨厚层纹层状大理岩化微细—细中晶灰岩,因具有高密度、抗风化、抗冻、耐碱、耐水、刚度大于普通灰石、抗变形能力大于混凝土等特性而被广泛应用于徽州地区明清古建筑。燕山期黟县花岗闪长岩体的侵入使灰岩发生大理岩化,对矿石品质的提升起着积极的作用。在矿产勘查的基础上,通过对西递水口亭地区黟县青石材矿成矿地质条件、矿体(矿石)特征和矿床成因的研究,为皖南地区该矿种的勘查、研究和开发利用提供重要的基础资料。″Yixianqing″is a unique local craft building stone in Yixian County,Xidi,southern Anhui.The ore-bearing stratum is the Cambrian Dachenling Formation formed in the shallow marine shelf facies,which is mainly produced in the Lantian syncline basin.It is a marmarized limestone deposit controlled by sedimentary genesis,and the ore body is strictly controlled by the stratum occurrence.The host rock stratum of the″Yixianqing″stone mine is dark gray,extremely thick,laminated,marmarized,microfine-fine icrotake crystalline limestone,which is widely used in the ancient buildings of the Ming and Qing dynasties in Huizhou area because of its high density,weathering resistance,frost resistance,alkali resistance,water resistance,stiffness greater than ordinary limestone,and deformation resistance greater than concrete,etc.The intrusion of Yanshanian Yixian granodiorite resulted in the marmarization of limestone,which played a positive role in improving the ore quality.On the basis of mineral exploration,this paper studies the metallogenic geological conditions,ore body(ore)characteristics and deposit genesis of the″Yixianqing″stone mine in the Shuikouting area,providing important basic data for the exploration,research,development and utilization of this mineral in southern Anhui.
