摘要
巴仁扎拉格铀矿赋矿岩体为巴仁扎拉格碱性花岗岩,岩体上部蚀变强烈,依蚀变强度可分为强-中-弱三个蚀变带,强蚀变钠闪石花岗岩带是主要矿化赋存部位,分布在蚀变岩体的上部。蚀变类型主要为钠长石化及硅化,次为霓石化、泥化等。钠长石化、硅化作用较强烈,在平面上,岩石均匀蚀变,垂向上,向深部蚀变逐渐减弱。铀矿化主要分布在强蚀变钠闪石花岗岩带,严格受岩体蚀变强度控制。矿床的成因属岩浆晚期分异交代型原生矿床。
Barenzhalage uranium ore rock is Barenzhalage alkali granite,upper rock intense alteration,according to the intensity of alteration can be divided into three alteration belts of strong,medium,weak,riebeckite granite belt of Strong alteration is the main mineralization occurrence location,located in the upper part of the alteration rock.The main types of alteration is silicification and albitization,followed by aegirinization,argillization,etc.Silicification and albitization relatively strong,the rock alteration uniformly in the plane,but to the deep alteration weakened gradually.Uranium mineralization are mainly distributed in riebeckite granite belt with strong alteration,and strictly controlled by the strength of rock alteration.The origin of mineral deposit is metasomatic differentiation primary deposit in the late magmatic.
