五大连池近代火山老黑山火烧山火山喷发过程的考察研究

作者在已有工作的基础上，以当代火山学的研究思路和观点，为恢复五大连池两个近代火山，老黑山火烧山的喷发历史过程进行了野外考察研究工作。老黑山火山锥是由三套不同的碎屑堆积物组成。在锥体的南侧、东侧和西侧以及北测和北西侧有５个熔岩溢出口，按它们形成先后关系，认为有早、中、晚三期熔岩流。本文还对老黑山火山锥上的寄生火山、结壳熔岩与渣状熔岩的分布、流动特点及形成的控制因素进行了分析讨论。最后得出结论：老黑山火山是经多期次喷发活动形成的。火烧山火山锥是一碎屑化泡沫化程度很低的浮岩块和熔岩碎块组成，同老黑山有明显区别。

INVESTIGATION OF VOLCANIC PROCESS FOR LAOHEISHAN AND HUOSHAOSHAN TO ERUPT CONCE RNING MORDEN VOLCANISM IN WUDALIANCHI REGION

Volcanic eruption process of Laoheishan and Huoshaoshan has been investigated by means of the morden theory of volcanology.Laoheishan's volcanic cone consists of three series of different volcanic cinders pile.Five overflows of volcanic magmasare located at the south side of the cone,the east, the west,the north and the north west side,respectively.The volcanic magmas flows can be separated into three times in sequence:earlier,mid and later period.The cnclusion is that Laoheishan volcano underwent multi period eruption activity.
