Based on the geologic occurrence,petrologic and isotopic age characteristics,authors of this article have identified 2 suites of dacite at Xiangshan uranium ore?field,and recognized that rhyolite?dacite is of volcanic effusion phase,but rhyolite?dacite porphyry belongs to hypabyssal intrusive phase.
本文从地质产状、岩石学和同位素年龄等特征出发 ,对相山铀矿田的两套英安岩进行了厘定 ,指出流纹英安岩为溢出相岩石 ,而流纹英安斑岩为浅成侵入相岩石 ,两者系不同时期形成的产物。
