Abstract: The tectonic affinity of South China in paleogeographic reconstructions of the Gondwana supercontinent during the Early Paleozoic remains controversial. Here, we present new detrital monazite U–Pb age data from Lower Devonian Posongchong Formation clastic sedimentary… read more here.

Abstract: The Bruce Rise, a prominent bathymetric feature offshore the Bunger Hills (East Antarctica), has basement of unknown crustal affinity and age. In East Gondwana, the Bruce Rise is reconstructed near the Naturaliste Plateau (offshore SW… read more here.

DOI: 10.1016/j.lithos.2020.105921
Abstract: Abstract The Indochina block is one of a number of continental fragments that lay along or outboard of the East Gondwana northern margin. Its early Paleozoic tectonic nature and the relationship with East Gondwana remain… read more here.

DOI: 10.1080/00206814.2016.1198994
Abstract: ABSTRACT Zircon U–Pb ages and geochemical and isotopic data for Late Ordovician granites in the Baoshan Block reveal the early Palaeozoic tectonic evolution of the margin of East Gondwana. The granites are high-K, calc-alkaline, metaluminous… read more here.
