The rocky silicification in fault zone is controlled by various tectono-geochemical agencies:the dynamo-differentiation and chemical affinity,the dynamothermal meta- morphism and diaphthorisis,the oxidation and reduction,the hydrolysis and dewatering.

• 断裂带岩石的硅化现象是受组成岩石的化学元素的构造地球化学作用所制约的,包括动力分异和化学亲和作用,动热变质作用和退化变质作用,氧化和还原作用以及脱水和水解作用。
