In this paper,a 3-D geological model for the Jiujiang-Ruichang ore concentration area was constructed by using a series of integrated geophysical interpretation profiles based on the stereoscopic geological mapping graphic system developed by MAPGIS K9 platform,and the accuracy of this 3-D model was proved through drilling verification in two different target zones of the srea.The results achieved provide more intuitive information for understanding the deep geological structure of the area and exploring the deep mineral resources prospective areas in the Jiujiang-Ruichang ore concentration area.
