It is rare to find earthquakes with depths greater than 30 km in continent–continent collision zones because the mantle lithosphere is usually too hot to enable brittle failure. However, a handful of small, intermediate-depth earthquakes (30–97 km) have been recorded in the continental collision region in central South Island, New Zealand. The earthquakes are not associated with subduction but ...
[1] The Eocene India-Eurasia collision is a first order tectonic event whose nature and chronology remains controversial. We test two end-member collision scenarios using coupled global plate motion-subduction models. The first, conventional model, invokes a continental collision soon after 60 Ma between a maximum extent Greater India and an Andean-style Eurasian margin. The alternative scenari...
Abstract Accurate lithostratigraphy framework of the Central Qilian belt is key to understand subduction-collision Proto-Tethyan Ocean in NE Tibetan Plateau. The Dongchagou and Moshigou formations share similar detrital zircon age populations with youngest peak at ca. 1.15–1.21 Ga, which consistent granitoid gneiss Liujiatai Formation. In combination rock assemblages, metamorphic facies, associ...
