Geology, fluid inclusions and isotope geochemistry of the Herenping gold deposit in the southern margin of the Yangtze Craton, China: A sediment-hosted reduced intrusion-related gold deposit?

摘要

The Herenping gold deposit is a typical gold deposit in the Xuefengshan arcuate tectonic zone in the southern margin of the Yangtze Craton, and the major feature of the gold mineralisation in the zone is the varying degrees of tungsten and antimony mineralisation in the ore deposits. The Herenping gold deposit occurs in the reddish purple sandy slate in the middle section of the Madiyi Formation of the Neoproterozic Banxi Group and is controlled by the fault-fold zone associated with the Liulincha anticlinorium and F8 fault zone. However, its sources of mineralisation and relationships between hydrothermal fluids and magmatic rocks are unclear, which similar to those of many gold deposits in metasedimentary terranes in the worldwide.
