摘要
依据同位素年龄、地层的披盖关系、火山岩风化程度以及火山地貌等综合因素,将黑龙江省新生代火山划分为8期。其中,中新世与早、中更新世火山喷发的数量多、规模大,为新生代火山活动的高潮期。同时指出,五大连池老黑山、火烧山火山、镜泊湖全新世火山为活火山。
On the basis of the isotope age, superincumbent relation of the stratum, rate of decay ofvolcano rock, geomophic feature and so on, Cenozonic volcanoes in Heilongjiang province were divided into 8 stages. The volcano erupted many times and the scale was larger in miocene epoch and early-middle Pleistocene epoch. Cenozonic is a stage that the volcano actived violent. It is pointed out that the Laoheishan and Huoshaoshan in Wudalianchi area and Holocene volcanoes in Jingbohu erea are active volcano.
