摘要
从脉钨矿床形成时热液的流动、裂隙腔的闭合情况，得出了热液在裂隙腔内作对流循环运动的推论。从压力差、温度差、浓度差说明热液作对流循环运动的动力。通过详细观察研究西华山钨矿６２号脉，阐明了成矿时主要组分的平衡和脉侧围岩蚀变的形成。
The conclusion that thermal fluid circulates in the fissures was infered from study on migration of fluid and closure of fissures in the form of tungsten deposits. The differences of pressure, temperature and concentration provide motive for fluid circulation. According to the observation of the No.62 vein in the Xihuashan deposit, the balance of main constituents and wallrock alteration were dwelled.
