五大连池老黑山火烧山火山喷发物及形成的物理过程

Eruption products of Laoheishan and Huoshaoshan volcanoes and their forming physical process

以当代火山物理的观点和思路对黑龙江省五大连池老黑山火烧山进行了研究。在旧锥锥体上部发现滞后角砾岩，在其下部坡脚发现有涌浪（ｓｕｒｇｅ）堆积物的存在，对形成过程和机制做了一些解释。

With points of view of volcanic physics, Laoheishan and Huoshaoshan volcanoes were investigated in this paper. It was found that the lithic lag breecia exists in the upper parts of the old cone body, and the pyroclastic surge deposits exists in the bottom. The forming process and mechanism were discussed also.
