藏南喜马拉雅北坡二叠系基性火山岩位于聂拉木县色龙东山。岩石地球化学特征表明,无论是基龙组火山岩还是色龙群火山岩,都具有大陆拉伸-大陆裂谷环境火山岩系的主、微量元素地球化学特征。据此,判断两套基性火山岩的性质和喷发构造环境相同。该区二叠纪大陆拉伸-裂谷火山活动标志着冈瓦纳超级古大陆开始裂离、解体。
The Permian basic volcanic rocks on the northern slope of southern Himalayas are located in Seleong Hill, Nyalam County. The geochemical characteristics of rocks show that both the Jilongong volcanic rock and the Serengang volcanic rock have the main and trace element geochemical characteristics of the continental tensile-continental rift environment volcanic rocks. Accordingly, the nature of two sets of basic volcanic rocks is judged to be the same as the eruption tectonic setting. Permian continental stretching in the area - Rift volcanic activity marks the Gondwana super ancient continent began to split, disintegration.
