The position of South China in Gondwana remains controversial. In all previous models, the Yangtze and Cathaysia blocks, two major components China, were amalgamated by Tonian, was considered to be a single coherent block Gondwana. Based on summary critical reevaluation available paleomagnetic, paleontological, stratigraphic, detrital zircon data, we propose that blocks not juxtaposed until ear...

Paleogeographic reconstruction of Precambrian terranes reworked by Phanerozoic orogens (e.g., the Tibetan Plateau) results in complex lithotectonic relations due to intracrustal reworking tectonothermal events. Detrital zircon rare earth element (REE) databases at global (global major river sands) and regional (the Gangdese Mountains, southern Tibet) scales reveal trends Eu/Eu* that effectively...

Gondwanaland was a southern mega-continent that began to break up 180 million years ago. This article explores Gondwanaland�s modern history, its unexpected political and cultural purchase since the 1880s. Originating with geological palaeontological research in Gond region of Central India, �Gondwana� has become recognisable useful, especially settler colonial contexts. prospectus sets out pro...

Apatite fission-track analysis of samples covering a 4.2-kilometer vertical section from the western flank of Vinson Massif, Antarctica's highest mountain, indicates that the Ellsworth Mountains were uplifted by 4 kilometers or more during the Early Cretaceous following the initial separation of East and West Gondwana and accompanying the opening of the Weddell Sea. Relief of at least 1.8 kilom...

Overseas dispersals are often invoked when Southern Hemisphere terrestrial and freshwater organism phylogenies do not fit the sequence or timing of Gondwana fragmentation. We used dispersal-vicariance analyses and molecular timetrees to show that two species-rich frog groups, Microhylidae and Natatanura, display congruent patterns of spatial and temporal diversification among Gondwanan plates i...

Late Precambrian to early Cambrian sediments of the Amadeus Basin, Central Australia, contain two stable directions of magnetization. Lithologies are diverse and include red beds, green beds, and carbonates, all of which respond to thermal cleaning. Positive fold and unconformity tests, and a well-defined polarity zonation reveal the primary component and direction of magnetization. This direct...
