| 摘 要： | 黑龙江省是中国新生代火山岩广泛分布的地区之一。通过对该省新生代火山岩构造环境的分析指出，本省西部火山岩区为大陆板内裂谷环境，地慢上隆、底辟是裂谷形成火山与地震活动的主要原因，而东部火山岩区火山与地震活动的动力则主要来自西太平洋板块对欧亚板块的俯冲作用。

| Abstract: | Heilongjiang Province is one of widely distributive region of the cenozoicEra volcano rock in China,Having analyzed tectonic environment of the Cenozoic Era volcanorock in the province,it can be pointed out that volcanic rock regionin West Heilongjiang is a rift valley belt in continental plate. Rift valley,volcano and seismicity are chiefly due tomantle tipwarp. Power of volcano and seismicity in East Heilongjiand volcano rock region re-sults from subduction of West Pacific plate. |
