摘要
新建上二叠统敌布错组,发现其中含有Noeggerthiop-Pterophyllum混生植物群,并确定该组与下伏地层为角度不整合接触关系。在冈底斯岩浆弧中新发现第四纪全新世火山岩,获取一批同位素定年资料,进一步丰富了冈底斯岩浆演化的时空格架。
The Upper Permian Dibucuo Formation is newly established. It contains the Noeggerthiop-Pterophyllum mixed flora and has an unconformable contact with the underlying strata. Holocene volcanic rocks are found in the Gangdise magma arc and a group of isotopic dating data are obtained, which further enriches the temporal-spatial framework of the magmatic evolution in Gangdise.
