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。

Neoproterozoic Baoxing Complex in middle to lower metamorphic grade, located in western margin of Yangtze Craton, consists mainly of metamorphic gabbroic, dioritic gneisses, tonalitic and granodioritic gneisses, and massive monzogranites The studies of petrochemistry and SmNd isotopes of Baoxing Complex reveal that the gabbroic and dioritic magmas came from a congenetic magma derived from the partial melting of spinel lherzolites in depletive mantle, and that the magma was intensively contaminated by crustal materials during its emplacement The tonalitic and granodioritic magma were derived from the partial melting of metamorphic basalts in the lower crust And the monzogranitic magma was formed from partial melting of metagreywacks Integrating the lithological association, their trace elements, SmNd isotopic characteristics and petrogenesis, the Baoxing Complex must likely have been emplaced in an island arc tectonic background at the Neoproterozoic active continental margin of Yangtze Craton
位于扬子克拉通西缘的新元古代宝兴杂岩主要由中低级变质的辉长质片麻岩、闪长质片麻岩、英云闪长质到花岗闪长质片麻岩和块状二长花岗岩组成。岩石地球化学和SmNd同位素特征表明,辉长质片麻岩和闪长质片麻岩为同源岩浆演化序列,原始岩浆起源于亏损地幔尖晶石橄榄岩的部分熔融,在上升和侵位过程中受到了地壳岩石强烈混染。英云闪长质和花岗闪长质岩浆形成于下地壳玄武质岩石部分熔融,而二长花岗质岩浆形成于杂砂岩的部分熔融。综合分析宝兴杂岩的岩石组合、微量元素和同位素特征,该杂岩体最有可能形成于新元古代活动大陆边缘火山弧构造背景,并可能经历了碰撞过程。

Abundance of salt-alkaline megatherm Classopollis-Ephedripites assemblage in a limited time illustrates a short duration of dry hot climate by latest Cretaceous. Such extreme climatic change and ecologic overturn are possible causes of the dinosaur extinction in the study area. Other factors, such as asteroid impact and large volcanic eruption triggering global mass extinction caused the regional climate change.
嘉荫群上部渔亮子组中膏岩层和耐高温、抗盐碱的克拉梭粉-麻黄粉组合在短时间内的大量出现,说明晚白垩世末期出现有短暂的干热气候,这种气候的突然转变以及伴随的生态系统的紊乱可能是嘉荫地区恐龙大量死亡的重要原因,但不排除诸如天外星体碰撞地球、大规模火山喷发等引发白垩纪末恐龙全球灭绝的因素,后者更可能是引起气候变化的直接因素。

Pacific plate subduction was dominated in study area since late Jurassic, stress regime was then transited from compression into extension associated with the steepening of subduction angel and retreat of subduction zone ocean inward; due to the difference in basement properties, extensional rifting basins dominated by depression basins developed within the Yangtze block, while volcanic faulting bounded basins for the Cathaysia block, and a series of red faulting bounded basins with half graben shape for the areas within the boundary zone between these two blocks.
晚侏罗世以后,太平洋板块对研究区的影响占主导地位,随着俯冲角度的变陡和俯冲带向洋的后撤,全区由挤压为主转变为以拉张为主的应力环境,由于基底属性有所差异,在扬子地块区域形成以拗陷盆地为主的伸展裂陷盆地,在华夏地块区域形成了火山断陷盆地,而在两大地块边界附近,则形成了一系列半地堑式的红色断陷盆地。
