Data for: Origin and Evolution of the Neoproterozoic Dengganping Granitic Complex in the western margin of the Yangtze Block, SW China: implications for Breakup of Rodina Supercontinent

This contribution presents new magmatic zircon U–Pb geochronology, Hf-O isotope and whole rock Nd isotope to constraints on the origin and tectonic setting of the Dengganping Complex along the western margin of the Yangtze Block. The results of and geochemistry provide a better understanding of the tectonic setting for the Neoproterozoic magmatic rocks in the study area, which are placed in context with the breakup of the Rodinia Supercontinent.

本研究报道了一套全新的岩浆锆石U-Pb地质年代学、Hf-O同位素以及全岩Nd同位素数据，以约束扬子地块（Yangtze Block）西缘邓干坪杂岩的成因与构造背景。上述同位素与地球化学分析结果，为深入理解研究区新元古代岩浆岩的构造背景提供了更清晰的认知，并将该套新元古代岩浆岩的构造背景置于罗迪尼亚超大陆（Rodinia Supercontinent）裂解的区域构造框架之中。
