人们一般认为火山喷发与水成的煤及有机成因的烃没有什么内在联系。笔者根据所获的地质资料分析认为,东北地区中新生代多旋回的火山喷发与多期的聚煤、聚烃作用是纵贯本区的古裂谷形成作用中的各个环节,它们在时空分布和成因上有着密切的联系,明显地受地球动力学机制制约。聚烃前的聚煤史无论在构造演化或物质转化上都对大型陆相油气田的形成有重要意义。
It is generally believed that volcanic eruptions are not intrinsically linked to hydrated coal and organic-forming hydrocarbons. Based on the geological data obtained, the authors believe that Mesozoic-Cenozoic multi-cycle volcanic eruptions and multi-period coal-accumulating and poly-hydrocarbon interactions in the northeastern region are all links in the formation of the ancient rift valley throughout the region. Their spatial and temporal distribution It is closely related to the genesis and obviously constrained by the geodynamics mechanism. The history of poly-coal before coal accumulation is of great significance to the formation of large-scale continental oil and gas fields in terms of tectonic evolution and material transformation.
