Metasomatism of the granitic rocks in Zhejiang Province, China is investigated by petrography. 用岩相学方法研究浙江花岗岩的交代作用。
Due to chemical erosion and metasomatism, some formations have developed secondary pores, and favorable reservoirs can also be found in deep layers. 受溶蚀和交代作用的影响，部分层位次生孔隙发育，深层中也存在物性较好的储层。
