次生石英岩是1901年蘇聯地質學者費特洛夫和泥紀金在北烏拉爾博古斯洛夫斯基山區的地質研究專著中所提出的關於圍岩蝕變的一個嶄新的名詞,他們所指的是一種從安山斑狀岩和凝灰岩等所變成的矽化岩石。但其中所含SiO_2的含量,與其原生岩石所含者大致相仿,即含60％左右。後来這個名詞被廣泛地應用到各種矽化岩石方面去,甚至包括了從火成岩(侵入岩及噴出岩都有)到沉積岩以至變質岩所成 Secondary quartzite is a new term for wall rock alteration proposed by the Soviet geologists Fettlv and Nguyen in Geological Research Monographs of the Northern Urals in the Boguzlovsky Mountains in 1901. They refer to Is a silicified rock that turns from andesitic porphyrite and tuff. However, the content of SiO 2 contained therein is roughly the same as that contained in the original rock, ie about 60%. Later on, the term was widely applied to various silicified rocks, even from igneous rocks (both intrusive rocks and expelled rocks) to sedimentary rocks and even metamorphic rocks
