在浙赣中生代火山岩地区相当广泛地发育着一种富晶屑或碎斑的酸性火山岩。它们堆积巨厚、分布面积广、生成时间大致相当。其中已陆续发现了铀、金及其它金属矿产。本文对相山及邻区碎斑流纹岩的特征和成因进行研究,对浙赣地区这种富晶屑流纹质火山岩的共性、成因和地质意义进行探讨。 In the Cenozoic volcanic rocks of Zhejiang-Jiangxi region, a kind of acid-rich volcanic rocks rich in crystal or crust are developed quite widely. They accumulate huge thickness, the distribution of a wide area, the generation time is roughly the same. Among them, uranium, gold and other metal minerals have been discovered one after another. In this paper, the characteristics and genesis of the crust rhyolite in the Xiangshan and its adjacent areas are studied, and the commonness, genesis and geology significance of this kind of crystal-rich rhyolitic volcanic rocks in the Zhe-Gan region are discussed.
