WebFeb 1, 2024 · The time and mechanism of crustal thickening and initial surface uplift of the Tibetan Plateau remain highly controversial. Here we report on zircon U-Pb age, and mineral, element, and Sr-Nd isotope composition data for Eocene adakitic porphyries in the Laorite Co area of central-northern Qiangtang Block, central Tibet. WebAs a hot resarch topic, deep geothermal energy has been studied worldwide. The present-day crustal thermal state is the final result of the lithospheric thermal evolution and is mainly influenced by the latest tectono-thermal events. ... Hot dry rock (HDR) is defined by the rock underground with high temperature but lack of fluid due to low ...
