摘要
镇安镇区域地质调查中发现该区有一典型特征的火山构造活动,属一次性喷发。火山活动 对镇安镇区内多个金矿体的形成起到重要作用,通过对该火山岩石结构、构造特征及火山机构特征 的研究,初步探讨了金矿点的形成与火山活动的关系。
It has been found that there is a classic volcanic-tectonic activity in Zheng'an Town during a regional geological survey in the region, which belongs to the temporary eruption and played a very important role in several orebodies' formation in Zhengan Town area. The relationship of gold mineralization with volcanic activity is discussed according to the study of volcanic rock structure, tectonic character and the volcanic mechanism characteristics.
