Abstract: Ganheba gold deposit is a tectonic altered rock type gold deposit controlled by both lithofacies and structure in the Mianluekang tectonic melange belt of the southern section of the southern Qinling mountains.The ore bodies are concentrated in the vicinity of the lithologicalstructural contact zone between the Ginjihe phyllite and the Qiaozigou volcanic rocks of the devonian jinjihe formation in the Paleozoic.The oreforming geological characteristics,geochemical background and sulfur isotopes of the ore deposit are summarized.After regional metamorphism,deformation and multistage tectonic activities,the oreforming materials in the source layer are activated and migrated,and the oreforming materials are filled and deposited in the EWtrending tensile fractures to enrich the oreforming process.

Key words: gold deposit, geological characteristics, genesis
