Investigations into three Permian-Triassic sections (the Selong Xishan, Qubu and Tulong sections) suggest the widespread distribution of the Lopingian Series (Late Permian) and the continuous Permian-Triassic bound-ary in southern Tibet. The Lopingian series in southern Tibet is characterized by containing typical Gondwana-type brachiopods such as Taeniothaerus, Fusispirifer, Neospirifer (Neospirifer) kubeiensis, Retimarginifera xizangensis and Spiriferella rajah, which suggest a correlation with those known from the upper part of the Wargal and Chhidru Formations in the Salt Range, Pakistan, the Zewan Formation in Kashmir, the Basleo Bed in West Timor, the Senja Formation in Northwest Nepal and the Hardman Formation in Western Australia. According to the occurrences of the conodont Clarkina dukouensis zone in the middle part of the Wargal Forma-tion and the Clarkina longicuspidata zone in the lower part of the Chhidru Formation, and the association with the ammonoid Cyclolobus and the foraminifer Colaniella fauna in the Salt Range, the Selong Group in the Hi-malayan region, as a whole, is considered to be Lopingian in age.The Himalayan Lopingian Series represents a third-order sequence and can be divided roughly into two dif-ferent sedimentary types. The Qubu-type Lopingian represents deposits developed in restricted coastal environ-ments along the northern peri-Gondwana continental margin. The Qubu Formation in the lower part consists mainly of quartzose sandstone interbedded with black shale containing the Glossopteris flora. The Qubuerga Formation in the upper part is composed of a siltstone- and bioclastic limestone-dominated member in the lower part with abundant brachiopods and a shale- and siltstone-dominated member in the upper part with the Atom-odesma fauna and abundant terrestrial palynomorphs and acritarchs. The Selong-type Lopingian represents a sequence developed on the inner shelf and is composed of the Selong Group dominated by carbonates with nu-merous brachiopods and a Waagenites bed in the lowest Kangshare Formation.
