Provenance and tectonic implications of the Yanshi bauxite area in Western Henan, China

The bauxite layer in Western Henan supplies a large number of ores and is useful for studying tectonic movement. In this paper, the samples were selected to carry out LA-ICP-MS detrital zircons U-Pb dating Hf isotope testing. results indicated that with Early Paleozoic ages mainly derived from North Qinling Orogenic Belt. Precambrian age may be basement China Block study support opinion Belt has been uplifted at ~310 Ma, surface southern craton an overall north-dipping topography time.
