The large scale and high grade of the Jiapigou deposit have so far collected more than one hundred years of mining history. Over the years, a great deal of data have been accumulated during the mining and exploration of the mine. I. Geological Overview of the Mining Area The mining area is located in the east-west complex of Yinshan End of the junction with the Xinhuaxia Zhang Guangcai Ling 1. Stratigraphy: In addition to the valley to see the modern alluvial deposits, most of the former Sinian old metamorphic rocks.Studies generally 40-60 ° north east, with a tendency to the south , Angle 30-45 ° (Figure 1). See the phenomenon of local bending. Metamorphic rocks in the area
