摘要
德江县大元萤石矿床位于务川汞矿带金鸡岭背斜的南东翼,矿体(脉)赋存于寒武系下统清虚洞组第一段白云质灰岩中,产出层位独特,矿物组合简单,矿石质量尤佳。经初步研究认为,萤石矿床的形成与地下低温热卤水的活动有关,并严格受张性断裂、岩相古地理和地层岩石组合的综合控制,具有明显的层控特征,其成矿时代归属燕山期。
Dayuan fluor deposit is located on the south -east leg of Jinjiling anticline, Wuchuan mercury deposit belt in Dejiang county. The ore body occupies in the first dolomitized limestone of the Qingxudong formation in low Cambrian, the occurrence layer is special, the mineral combination is simple and the quality is high. By primary research, the formation of fulor deposit has relationship with the activities of low temperature thermal brine, and it＇ s controlled by tensile fracture, lithofacies ancient geology and rock association strictly. The strata- binding is obviously and the mineralization is in Yanshan stage.
