Petrology and Geochemistry of the Huangshan Granitic Intrusion in Anhui Province, Southeast China: Implications for Petrogenesis and Geodynamics

The Huangshan granitic intrusion, located at the southeastern boundary of the Yangtze Block in Anhui Province, China, reveals significant insights into the petrogenesis and geodynamics of southeastern China during the Late-Mesozoic. This study identifies four distinct stages of granite formation, characterized by high silica (SiO2 > 75%), alkali content, and low calcium (CaO < 1%). The granites exhibit A-type characteristics, such as enrichment in rare earth elements (REE) and high-field strength elements (Zr, Hf, Nb), while being depleted in Ba, Sr, and Ni. Geochemical and isotopic analyses suggest that the primary magmas originated from Proterozoic andesitic rocks, providing a deeper understanding of the region's geological history.
