摘要
///This paper focuses on petrography, mineral composition and varieties of Qingtian stone, suggesting that hydrothermal metasomatism and metamorphism of intermediate-acid volcanic rocks lead to the formation of the stone. It is suggested that determination of alteration zone of volcanic rocks of Mesozoic and Cenozoic Era by means of geological mapping is an effective way of looking for the high quality Qingtian stone, and must be concerned in the identification and subsequent evaluation of the stone.
