摘要

Late-stage early Yanshanian granitoids metallogenesis are widely distributed in South China and closely related to patterns, being EW-trending in Nanling and NE-trending in Wuyi area. Granitic rocks formed in two different tectonic settings have different geochemical characteristics. The results show that the mainland lithosphere of Nanling and adjacent regions belonged to art extensional setting, Southeast China was mostly under the tectonic framework of East Asia active continental margin, and the collision and compressional role of the Pacific Plate toward East Asian continental margin began to emerge.
