| Abstract: | The Jiangken Au deposit is situated at the junction of the zhenghe-Dapu NE-trend fault zone and the Ninhua-Nanping NEE-trend fault zone,which is located at border on Songxi-Jiangxi depression and Pucheng-Yangyuan uplift.Au orebodies are found in fault belt of nappe structure and steep fault in metamorphic rock.Au-Ore is derived form metamorphic rock and magmatic rock.The main genetic types of deposit belong to the migmatization metamorphic-hydrothermal Au deposit. |
