The giant Jiaodong gold province: The key to a unified model for orogenic gold deposits?
Geoscience Frontiers, 2016 AbstractAlthough the term orogenic gold deposit has been widely accepted for all gold-only lode-gold deposits, with the exception of Carlin-type deposits and rare intrusion-related gold systems, there has been continuing debate on their genesis. Early syngenetic models and hydrothermal models dominated by meteoric fluids are now clearly unacceptable ...
