围岩蚀变类型较多而且复杂，主要有硅化、滑石化、黑云母化和白云岩化。
矿体至围岩明显有矽卡岩化-强硅化-弱硅化-石英、碳酸盐化的蚀变分带特征。
蚀变是区内的找矿标志之一，金矿的形成与硅化、褐铁矿化、黄铁矿化等蚀变有关。
1·Because of the deposition time and the degree of silicification of different bedding structure very different form, Qianceng stone to jade ancient depositional age.
因其沉积年代及硅化程度的不同，形成的层理结构迥然有异，沉积年代久远的千层石近于玉质。
2·Because of the different of the deposition time and the degree of silicification, the bedding structure formed different, depositional age old Melaleuca stone near the jade.
因其沉积年代及硅化程度的不同，形成的层理结构迥然有异，沉积年代久远的千层石近于玉质。
3·The gold mineralization is represented by the association of silicification, dolomitization and pyritization.
矿化表现为“硅化、白云石化、黄铁矿化”组合。
4·The meta-somatic processes predominating in the granitic rocks in Zhejiang Province include alkali enrichment caused by metasomatism, i. e. seriatization, microclirization, and silicification.
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。
5·Wall rock alterations include sericitization, silicification, potassic feldspathization, biotitization, pyritization, hematitization and hydrous kaolinization.
绢云母化、硅化、钾长石化、黑云母化、黄铁矿化、赤铁矿化及水合多水高岭石化等。
