Abstract方解石是湘黔汞矿带的主要脉石矿物。湘黔汞矿带各矿床方解石的稀土配分模式均为轻稀土富集的右倾型,中段的大硐啦、茶田方解石和围岩的稀土配分模式比较相似,只是稀土总量有差别;南段的万山方解石和围岩的稀土配分模式则不一致,围岩的稀土总量反而要高于方解石。南段的万山方解石稀土具有弱的负Eu、负Ce异常;而中段的大硐喇、茶田方解石具有负Eu、正Ce异常。其中,作为示踪流体过程重要参数的Y/Ho比值在湘黔汞矿带南段与中段的方解石中也有着较大的差别。方解石的C、O同位素特征揭示南段万山汞矿的形成与古油藏的有机质有关,而中段大硐喇、茶田汞矿的形成则与有机质无关。这都说明了南段与中段无论是成矿物理化学环境还是成矿热液流体的性质等都存在着较大差别。
