| 摘 要： | 大兴安岭北段阿龙山地区,发育有6个环状火山盆地,根据它们的形成、演化的地质、地球物理标志,可划分为未成熟、成熟与老年三种火山构造盆地类型.各种火山构造盆地的地质、地球物理特征与类型标志明显,又都经历了环状产生与基性火山喷发、酸性岩浆活动、晚期基性火山喷发3个演化阶段,形成了中基性-中酸性—中基性的演化过程.

| Abstract: | There are six ring-shape basins in the Arlongshan region,northern part of Daxing'an Mountain,which can be divided into three types;immature,mature and elderly volcanic basin structures,showing obvious geological and geophysical features of the ring volcanic basin.They occurred the ring structures' formation,basic volcanic eruption,acid magma tic activities and elderly basic volcanic eruption,formed the intermediate basic,intermediate acid-intermediate basic evolution process. |
