Late Triassic Tectonic Setting in Northeastern Margin of North China Craton: Insight into Sedimentary and Apatite Fission Tracks

چکیده
The closure timing of the Paleo-Asian Ocean and terminal stage Central Asian Orogenic Belt have been widely debated in geological community. It’s known that gradual scissor-like occurred from west to east during Paleozoic period. However, it was not until Triassic period complete ocean at northeastern margin North China Craton. Nevertheless, there is still much uncertainty regarding Late tectonic setting Northeast China. In this study, we focused on Upper Dajianggang Formation, located Shuangyang area central Jilin Province, which situated Plate. Our aim determine formation age Formation by analyzing detrital particle composition, petrogeochemistry, zircon U-Pb isotope dating, apatite fission track thermochronology. results indicated primary sandstone provenance island arc orogenic belt. background mainly a continental environment. mostly composed felsic rocks with sedimentary tendencies, some its material may originated northern Craton or eroded recycle LA-ICP-MS dating zircons shows formed after 226.8 ± 5 Ma. Moreover, analysis thermal evolution history modelling continued be deposited heated early stage, then experienced rapid exhumation around 30 This suggests study underwent an process formation, but transitioned into post-orogenic extension period, constrained final prior addition, our indicates remote effect Pacific subduction did reach sample 19DJ-1 94.2 8.3 Ma, younger than corresponding stratigraphic age. two peak ages are 62.9 5.4 Ma 126 11 These findings provide new evidence for shed light setting, as well influence time subsequent domains southern part

Both highand medium-pressure granulites have been found as because of the absence of modal minerals. The combination of petrographic textures, mineral compositions, metamorphic reaction enclaves and boudins in tonalitic–trondhjemitic–granodioritic gneisses in the Hengshan Complex. Petrological evidence from these history, petrogenetic grids and thermobarometric data defines a nearrocks indicate...
