龙岗火山群位于龙岗山脉中段,处于阴山——天山东西向复杂构造带东延部分的北缘与新华夏系第二巨型隆起带的交汇部位。东西长约70公里,南北宽约20公里,构成了东西走向的火山口带。龙岗火山群主要为中心式喷发,其中个体较大,地貌反映明显的火山口达164个之多。远望广阔的玄武岩台地,岩流方向、期次清晰可辨;俯瞰群集的火山锥景观,分布方向、机制井然有序。该火山群正处青年时期,火山地貌明显,火山锥多数保持完整,为我们今天研究龙岗火山群的形成提供了有利的条件。
The Longgang volcanic group is located in the middle part of the Longgang Range and is at the intersection of the northern margin of the eastward-extending part of the Yinshan-Tianshan east-west complex structural belt and the second giant uplift belt of the Xinhuaxia Formation. Some 70 km east-west, north-south width of 20 km, forming the east-west crater belt. Longgang volcanic group is mainly central eruption, of which larger individuals, the apparent topography of the volcano as many as 164. A wide range of basalt terraces, rock flow direction, a clear and identifiable period; overlooking the cluster of volcanic cone landscape, distribution, mechanisms and orderly. The volcano group is in its youth, obvious volcanic landscape, most of the volcano cone remains intact, for our study of the formation of Longgang volcano today provides favorable conditions.
