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.

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

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.

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.
