MIDDLE PERMIAN FUSULINIDS FROM THE XAINZA AREA OF THE LHASA BLOCK, TIBET

Over the past two decades, the interpretation regarding the paleogeographic evolution of the Lhasa Block has been rather controversial. Some believed that the Lhasa Block was located in the northern margin of Gondwanaland until Late Triassic (Norian) and then rifted from Gondwana (Metcalfe, 2002); while others argued that the rift took place in later Early Permian (Ueno, 2003). Fusulinids have been proved to be a useful fossil tool in Permian paleogeographic reconstruction (Sheng et al., 1981; Ozawa, 1987; Belasky et al., 2002; Ueno, 2003), thus a detailed study of the Permian fusulinids in the Lhasa Block could provide pivotal paleontological evidence for solving the aforementioned dispute.
