Radial Growth of Qilian Juniper on the Northeast Tibetan Plateau and Potential Climate Associations [PDF]
, 2013 There is controversy regarding the limiting climatic factor for tree radial growth at the alpine treeline on the northeastern Tibetan Plateau. In this study, we collected 594 increment cores from 331 trees, grouped within four altitude belts spanning the

Cenozoic paleostress field of tectonic evolution in Qaidam Basin, northern Tibet
Open Geosciences, 2021 This article analyzes the stress fields in the Qaidam Basin since the entire Cenozoic using finite element numerical simulations. The stress fields are investigated by analyzing tectonic joints and the GPS velocity field in the basin.
