2. This study shows that there are 4 kinds of volcanic facies in deep volcanics in north Songliao Basin: eruptive facies, overflow facies, volcanic vent facies and volcanic sedimentary facies. There are 4 volcanic eruption cycles: Huoshiling period, Shahezi period, Yingchengzi period and Quantou period. There are 4 structural evolution stages: north-south accumulation, west-east subduction, uplift mantle and thin crust, alternative open and close. There are 4 kinds of pool-forming patterns:(1) pattern with the migration along the unconformity and fault to the near crater; (2) pattern with the migration along unconformity and fault to the rift margin; (3) pattern with the migration along unconformity, fault and fracture to the source rock; (4) pattern with the migration of the deep gas along the deep and large fault to the volcanic trap.
    研究认为，松辽盆地北部深层火山岩主要存在四种火山岩相：即爆发相、溢流相、火山通道相、火山沉积相，划分为四个火山喷发旋回：即火石岭期、沙河子期、营城子期、泉头期，经历了四个构造演化过程：即南北夹攻、东西俯冲、幔隆壳薄、开合交替，具有四种成藏模式：即沿不整合面和断层运移至近火山口处火山岩圈闭聚集成藏模式、沿不整合面和断层砂岩疏导层运移至断陷边部火山岩圈闭聚集成藏模式、沿不整合面及断层、裂缝运移至源岩区内凹中隆火山岩圈闭聚集成藏模式、深部无机成因天然气沿深大断裂运移至火山岩圈闭聚集成藏模式。
