用岩相学方法研究浙江花岗岩的交代作用。浙江花岗岩的主要交代过程包括交代引起的碱性化,如绢云母化、微斜长石化和硅化。斜长石的绢云母化大量发生在低温低压条件区域,随热液进入,带入了过量水、K、Al和Si。在交代作用后期,更多的花岗岩形成,这些花岗岩可再熔化,熔化后又会凝固并被交代流体作用。 Study on the metasomatism of granite in Zhejiang Province by petrography. The main metasomatism of Zhejiang granite includes metasomatism caused by metasomatism, such as sericitization, micro-plagioclase and silicification. The sericitization of plagioclase occurs in large quantities in the low-temperature and low-pressure conditions, with the hydrothermal solution entering, with excess water, K, Al and Si. In the later stage of account metamorphism, more granites were formed. These granites could be remelted, melted, solidified and replaced by fluids.
