| Abstract: | By gravitational-magnetic data, the preliminary determination on the volcanic craters of basaltic outcrop areas in western Guizhou is carried out according to the characteristics of gravitational anomaly and air magnetic anomaly induced following the magnetic eruption on gravity and air magnetism. Accordingly, in investigation on geology and mineral and the ore-forming prospects are provided with valuable information . |
