| 1 | Volcanism in Sanjiang Tethyan Orogenic Belt:New Facts and Concepts显示文摘Sanjiang area in Southwestern China is tectonically sit-uated at the east end of Himalaya-Tethys tectonic do-main and at the conjunction of Tethyan MountainChain and Circum-Pacific Mountain Chain.It is one ofthe key areas to understand the global tectonics and alsoone of gigantic metallogenic provinces in China and evenin the world.Volcanism had occurred during the periodof time from Proterozoic to Cenozoic.The most impor-tant and active periods of volcanism,however,areCarboniferous,Permian and Triassic.The pattern ofspatial distribution of Sanjiang volcanic rocks andophiolites can essentially be described as that severalintra——continental micro-massif volcanic districts arerespectively sandwiched between each two of four couplingophiolite—are volcanic belts,which are successively fromwest to east:Dingqing-Nujiang belt,Laneangjiangbelt,Jinshajiang belt and Ganzi-Litang belt.Fourtectono-magmatic types of volcanic rocks have been recognized in Sanjiang area as | Mo Xuanxue Lu Fengxiang Deng JinfuChina University of Geosciences , Wuhan 430074 | 1991 | Journal of Earth Science1991，10，1： | 2 |
