摘要

The Nanling-Wuyi regions in South China collectively form a globally significant metallogenic province hosting a group of world-class W-Sn-Au-Cu ore deposits. The mineralization in Nanling and Wuyi regions exhibits typical zonation characteristics: the former is distinguished by extensive multi-episodes of granite emplacement and associated W-Sn mineralization; the latter is characterized by intense Yanshanian volcanic activities along continental margins and associated Au-Cu mineralization. The Nanling region has experienced multiple intensive tecto-magmatic movements, including the Caledonian, Indosinian, and Yanshanian periods. Its predominant W-Sn mineralization occurred during the Yanshanian period, governed by the combined effects of crustal reworking and a high degree of magmatic differentiation. In contrast, the Wuyi metallogenic belt experienced Mesozoic volcanic activities predominantly during the Middle-Late Jurassic, Early Cretaceous, and early Late Cretaceous periods. The Yanshanian Au-Cu mineralization in this belt results from the remobilization of ancient Au-Cu enriched crustal sources triggered by paleo-Pacific plate subduction. The distinct deep geological processes in the Nanling and Wuyi regions have fundamentally shaped their characteristic ore-related igneous rocks and mineralization types.
