The geochemical characteristics of Jianchaling gold ore deposit indicate that the Jianchaling ultramafic intrusion is the main source of gold and rockforming substances displays the mantlederived feature. The gold metallogenesis is related to early structure magmatic hydrothermal process and late structure hydrothermal alteration. Oreforming fluid was hybrid magmatic hydrothermal one and the late intermediateacid magmatic water was the main composition which is responsible for alteration metamorphossim of the ultramafic intrusion. The sulphur of gold mineralization was multiphase and polysources. The gold deposit should belong to orogenictype deposit; its metallogenic process can be diviede into two periods, Late JinningCaledonian and IndosinianYanshanian, with the latter being dominating one. The main oreforming time corresponds to the regional postcollisional orogeny. Therefore, intracontinental compressional orogeny formed its metallogenic geodynamics setting. Retrograde alteration of ultramafic intrusion, longterm activity of F451 fault and subsidiary fractures which intersect F451 at largeangles in its upper and heading side and its fissure system, and Dengying Group dolomite are main orecontrolled factors. Combined with exploration practice in this area, it is proposed that the fault belt, AuAgAsHgB geochemical exploration anomaly, as well as alterated dolomite are important indicators for prospecting. Therefore, the Jianchaling area is potential for mineral exploration, and this study has important realistic signification to guide prospecting and get breakthrough in the area.
