| Abstract: | There are three stages of tectonomagmatic event in the Yangla region,Yunnan Province,including ocean-ridge and ocean-island volcanic rocks of Hercynian in Jinshajiang rift-oceanic basin and syntectic granite of Indosinian and synorogenic granite porphyry of Yanshanian,which could have been caused his ocean-continent transfer(oceanic basin spreading and oceanic crust subduction and oceanic basin closeness) of Jinshajiang suture zone. The corresponding types of deposit in every stage of the tectonomagmatic activities, are classified into eruption-sedimentation type, skarn type and porphyry type. |
