Paleomagnetic Constraints on the Separation of the Olongbuluke Block From the North China Block During the Late Cambrian–Middle Ordovician and Its Tectonic Significance

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The collisional evolution of the micro‐blocks in the northeastern Tibetan Plateau is relatively well constrained. However, the reason why a fragment of the North China Block, the Olongbuluke Block, became separated from North China by the Central Qilian Block (a fragment of the South China Block) remains unclear.

Dynamic Changes of Aboveground Biomass of Vegetation in Qaidam Basin

IOP Conference Series: Earth and Environmental Science, 2020
Abstract In order to monitor the temporal and spatial dynamics of vegetation in the Qaidam Basin, the ground-based vegetation biomass model of the basin was established by using basin ground measurements data during 2016-2018 and NDVI of MOD13Q1: Y=0.0002X2-0.863X+2052.4(R2=0.7656, P<0.01), and using this model to estimate the long ...
