| 摘 要： | 本文论述了潼关金矿田含金石英脉蚀变矿化的主要特征,指出该矿田含金石英脉的蚀变围岩可分为两个带,即绢云母石英片岩带(或千枚岩带)和蚀变片麻岩带,认为整个蚀变带具典型的中温热液蚀变特征;在围岩热液蚀变过程中,Au、SiO_2、K_2O、CO_2和H_2O是带入组份,而Mg、Ti、Na_2O、Fe_2O_6、FeO和CaO是带出组份,Au未表现出明显的扩散效应.

| Abstract: | This paper expounded the main alteration mineralization features of gold-bearing quartz vein in the Tongguan goldfield and divided the alteration-sheathed rocks of the gold-bearing quartz vein in this goldfield into two zones, i. e.the zone of sericite-quartz schist ( or the phyllite zone ) and the zone of altered gneiss. The writer believed that all altered zones were of the typical characteristics of the altered medium temperature hot fluids.In the alteration process of the surrounding rock hot fluid, the Au, SiO2, K2O, CO2 and H2O are the entered compositions and the Mg, Ti, Na2, Fe2O3 FeO and CaO are the eliminated compositions, while the diffusion effect of the Au is not clear. |
