The Cathysia Block is an important part of the South China Block, which is located in its southeast, and playing a key role in its formation and evolution. The Precambrian basement of the Cathaysia has experienced Paleoproterozoic Columbia/Nuna, and Neoproterozoic Rodinia supercontinents, and Paleozoic Gondwanaland collision-breakup events since its formation. The Tianjingping metamorphic complex consists of schists, gniesses, amphibolites and migmatites, formed by complicated igneous-sedimentary series that has undergone greenschist-amphibolite facies metamorphism and local modification by anatexis. The Cathaysia evolution during supercontinents collision-breakup events would be well recorded in the Tianjingping Complex, for it is one of the important typical exposure areas of the precambrian basement and also contains Precambrian-Early Paleozoic sediments. This application proposed a systematic research on the Tianjingping metamorphic complex via detailed petrography, geochemistry combined with zircon LA-ICP-MS U-Pb dating, trace elements, and LA-MC-ICP-MS Hf isotopes analyses. This project would help to define the nature and environment of the ~1.77 Ga crystal basement and the sedimentary timing of different source rocks in the Tianjingping Complex, and would help tracing the sedimentary source area(s) of Cathaysia by comparison of the Hf isotope compositions for zircons with same ages in possible adjacent blocks in the supercontinents reconstruction models, including Paleoproterozoic Columbia supercontinent, Neoproterozoic Rodinia supercontinent and Early Paleozoic Gondwanaland. That would provide significant constraints on the tectonic evolution of Cathaysia and Precambrian-Early Paleozoic paleocontinents configurations.
