| 摘 要： | 沂沐裂谷是中国东部呈扇形展布的大陆裂谷系,从晚侏罗至白垩世裂谷岩浆活动强烈,发育了一套碱性、钙碱性火山建造,尤以中生代钙碱性火山活动具有特色,并常常形成许多巨大的古火山机体,本文通过对产于古火山机体中两个含金斑岩铜岩床研究,初步得出其主要成矿地质特征。

| Abstract: | The Yi-Shu paleorift is a sector of rift system in East China which is marked by in tensive magmatic activity from the late Jurassic to early Crefaceous so as to have developed a set of alkali and calc-alkali volcanic structures.The most spectacular activity occurcs in the lycsozoic calc-alkali volcanoes,often resul- ting a lot of huge paleo-volcano formation.Through the study of the two gold-bearing porphyry copper deposits is volcanic structure,we preliminarily know the main geologic character during mineralization. |
