Recent identification of tectono-metamorphic discontinuities within the Himalayan metamorphic core has challenged previous understanding of mountain-building processes/models during continental collision. However, their exact position, spatial extent, and temporal evolution still remain in debate. Monazite petrochronology and thermobarometry have been applied to metapelites of the Gyirong-Syabrubensi-Langtang

The 2008 MW 7.8 Wenchuan earthquake in China led to intensive studies on the development and dynamic mechanisms of the Longmen Shan fold-and-thrust belt. To construct the uplift history of the Longmen Shan, previous works had undertaken numerous low-temperature thermochronological studies in mountainous area, in particular apatite and zircon (U–Th)/He dating, which provided valuable evidence for understanding

The giant Dexing porphyry copper ore field, containing 9.7 Mt copper, is the largest porphyry copper system in South China. The petrogenesis of andesitic dikes in the Dexing ore field and their genetic link with porphyry mineralization remain unclear. This paper presents LA-ICP-MS zircon U-Pb dating, elemental and Sr-Nd-Hf isotopic data of the andesitic dikes in the Dexing porphyry copper ore field

Continental collision between India and Eurasia plates and associated compression result in the formation of the Tibetan Plateau with a mean elevation of >5000 m. However, how the plateau was formed is still under debate. In this study, by analyzing multiple topographic metrics in the Dadu River drainage basin, eastern Tibetan Plateau, together with previous studies, we attempt to unravel the landscape

This study presents the carbon isotopic record for terrestrial plant matter (δ13CTPM) in the Jinju Formation, Gyeongsang Basin, Korea, during the middle Albian. The measured δ13CTPM provides continuous high-resolution temporal variations for reconstructing climate change during the middle Albian, which has previously been poorly understood. We found that the δ13CTPM variation mostly exceeds the isotopic

Earth’s continents can come together to form supercontinents and the supercontinents can break apart into fragments of varying size scattering around the globe through a hypothetical process called continental drift. The continental drift hypothesis had survived after ∼ 60 years debate and evolved into the powerful theory of plate tectonics with unquestionable and irrefutable lines of evidence. This

The geochemical signatures of subducting crust have been identified in various types of mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and continental arc andesite are accepted as the typical products of subduction zone magmatism. These crustal signatures are commonly represented not only by enrichment in large ion lithophile elements (LILE) and light rare earth
