Happy Earth Science Week from the EarthByters! This is our annual chance to celebrate the science of the planet we all live on, and to share how much there is still to discover about it. The ground under your feet is moving. Right now, at about the speed your fingernails grow, and it has been … Read more…
Scientists studied granitoids from the Kangding area in the southeastern Tibetan Plateau, using new elemental and isotopic data, including the first silicon isotope measurements for these rocks, to trace how the plateau’s crust grew eastward over the last 35 million years. The granites fall into two groups, and one of them shows a temporary shift … Read more…
The Cenozoic collision of India and Eurasia clearly built the high-elevation Tibetan Plateau, but how this collision was accommodated, and the Tibetan Plateau uplifted, remains an area of study. The widespread occurrence of Cenozoic potassic–ultrapotassic lavas provides a valuable opportunity to constrain the relationship between surface deformation and underlying geodynamic processes. In this study, we … Read more…
Mantle heterogeneity in lithology and geochemistry is often attributed to recycled subducted materials. While distinct mantle end-members are identified by radiogenic isotopes, the specific recycled materials contributing to this heterogeneity remain debated. This study presents Mo-Sr-Nd-Pb isotopic data for OIB-like alkali basalts from the Maguan area in the southeastern Tibetan Plateau, focusing on slab inputs’ … Read more…
