Abstract:Huashan mine in Gaomi city is an important barite mining area in Shandong province. The mine is located in Jiaolai basin, and ore bodies occur in tectonic fracture zones of Yangjiazhuang formation in Laiyang group. It is strictly controlled by structures with the trend of NW, and five larger veins distributed in the region. Calcitebarite type is the main ore type. In this paper, the genesis of barite ore (epithermal fissure filling type), metallogenic model and prospecting signs have been analyzed. It has a certain guiding significance for further exploration in the mine and similar areas.
