The Karakoram fault (KKF) is an important strike‐slip boundary for accommodating deformation following the India‐Asia collision. However, whether the deformation is confined to the crust or whether it extends into the mantle remains highly debated. Here, we show that the KKF is overwhelmingly dominated by crustal degassing related to a ⁴He‐ and CO2...

Hydrothermal activity and seismicity are abundant along the Yushu-Ganzi-Xianshuihe fault system (YGXFS) in the eastern Tibetan Plateau. However, the processes and factors that control hydrothermal fluid circulation at a regional scale remain less constrained, and the relationship between geothermal anomaly and seismic activity is poorly known. In t...

The Tibetan Himalaya region provides crucial sedimentary successions for studying the evolution of the eastern Tethyan depositional area. However, the palaeo-environmental conditions during the Early Cretaceous period in southern Tibet (Tethys Himalaya northern zone) are not well constrained. In this paper, we report on the major, trace, and rare e...

A large number of gases are releasing from the medium-high temperature geothermal fields distributed along the large-scale strike-slip fault zones in the southeastern margin of the Tibetan Plateau. In this study, 11 hot spring water and the associated bubbling gas samples were collected along the Xianshuihe-Anninghe fault zones (XSH-ANHFZ) and anal...

Mesozoic and Cenozoic granites are widely distributed in the South Lhasa terrane of southern Tibet and record information about subduction of the Tethys oceanic plate and the India–Eurasia collision. This paper presents petrological, geochemical, zircon U–Pb and Hf isotopic characteristics of Cenozoic intrusive rocks in the Luocang area, South Lhas...

The Upper Jurassic–Lower Cretaceous Sangxiu Formation in the Rongbu area of Tibet is dominated by large–scale exposed basalts. This paper characterizes the geochemistry and magmatic activities of the Sangxiu Formation basalts in a geochemical analysis. The Sangxiu basalt has higher content of TiO2, TFeO and P2O5 (average content is 3.68%, 11.16% an...

Located within the centre of the Tethys Himalayas, the Weimei Formation of the Rongbu area in southern Tibet is a littoral- neritic sedimentary association composed of clastic rocks and a few shales. Petrologic characteristics and detrital component statistics indicate that sandstone types include lithic quartz sandstones, with the average content...
