摘要
中川岩体位于中秦岭华力西褶皱系礼县—柞水冒地槽褶皱带西段中部,为同心环状产出的复式岩体。围绕岩体产有中川铀矿田和李坝、马泉、崖湾等金矿床。其中铀矿化类型有钠交代型、硅质脉型、粘土型、硅质脉—粘土叠加型,不同类型的铀矿化其富集条件也各异。矿化成因有两种,岩浆期后热液成因和下降水淋积成因。
Located in the middle section of the west geosyncline fold belt in Lixian-Zhashui within the Her-cynian fold system in the middle Qinling,Zhongchuan pluton is a complex pluton with the occurrence of concen-tric ring.Around the pluton are there Liba,Maquan and Yawan gold deposit,and Zhongchuan uranium field.The types of uranium mineralization are sodium metasomatic type,siliceous venation type,chamotte type,siliceous ve-nation-chamotte composite type.The different type of uranium mineralization were caused b...
