| Abstract: | The Gudui area is located in the middle east of the Tethys-Himalayan orogenic belt,between the 2 great tectonic units,namely Southern Tibet Detachment System and Yarlung Zangbo Suture Zone,and one of its notable characteristics is the widely developed Mesozoic-Cenozoic magmatic rocks.On the basis of collecting data from regional geological survey(1∶50000)recently completed and related research achievements,this paper briefly introduces the stratigraphic and geotectonic background of Gudui area,and in detail describes geological features,petrological and mineralogical characteristics of magmatic rocks during different periods.Discussion and comparative analysis of the formation ages and characteristics of magmatic rocks basically find out the main rock types,phase division of the magmatic rocks and their relation with metallogenesis,and preliminarily established the metallogenic patterns.The study bears theoretical and practical significance in guiding the deployment of prospecting work in Gudui area. |
