The interaction of the northern Nazca and southwestern Caribbean oceanic plates with northwestern South America (NWSA) collision Panama-Choco arc (PCA) have significant implications on evolution Andes. Based a quantitative kinematic reconstruction Farallon/Farallon-derived plates, we reconstructed subducting geometries beneath NWSA PCA accretion to continent. persistent northeastward migration ...

(1) Background: The widely developed thrust structures in the Jingzhushan Formation of late Cretaceous Nyima Basin are related to collision which leads orogeny between Lhasa and Qiangtang blocks. Clarifying tectonic properties is great significance characterize evolution block block. (2) Methods: Combined with mineralogy petrology U-Pb zircon dating extrusive rocks, a detailed magnetic fabric t...

[1] Geoscientists use plate tectonics to explain many aspects of both continental evolution and evolution of the planet as a whole. The subduction of material at convergent plate boundaries forms a fundamental component to the theory of plate tectonics. Plates, continents, subduction zones, and spreading centers all exhibit motion and geometric evolution, so to try and resolve the past geometri...

The evolution of the Taiwan orogen, an active arc–continent collision zone between North Luzon Arc (NLA) and Eurasian continent, is recorded in arc volcanic sedimentary rocks from Taiyuan retro-foredeep basin Coastal Range, eastern Taiwan. volcanism northern NLA experienced a magmatic culmination at 9–7 Ma cessation 5.3–4.3 Ma, based on new U-Pb zircon ages. Young ages (1.74, 1.58, <1.2 Ma) low...

India's northward flight and collision with Asia was a major driver of global tectonics in the Cenozoic and, we argue, of atmospheric CO(2) concentration (pCO(2)) and thus global climate. Subduction of Tethyan oceanic crust with a carpet of carbonate-rich pelagic sediments deposited during transit beneath the high-productivity equatorial belt resulted in a component flux of CO(2) delivery to th...
