利用重磁资料对贵州西部玄武岩出露区火山口的初步圈定

Preliminary Determination on the Volcanic Craters of Basaltic Outcropped Areas in Western Guizhou by Gravitational-Magnetic Data

根据火山口及岩浆喷溢后可能在重力和航磁上引起的重力异常和航磁异常的特性,该文利用重磁资料对该区火山口进行了初步圈定。为该区的地质、矿产研究及成矿预测提供一点深部信息。

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 .
