Atmospheric CO2 Consumption by Chemical Weathering in the Main Tributaries of the Yellow River: Tao He, Huang Shui, and Datong He, Originating From the Northeastern Qinghai-Tibet Plateau

Frontiers in Earth Science, 2021
The Tao He, Huang Shui, and Datong He originate from the northeastern margin of the Qinghai-Tibet Plateau (QTP) and flow into the Yellow River on the Loess Plateau (LP), all with a basin area exceeding 15,000 km2, and are the three largest tributaries of

The weathering process of carbonatite: weathering time [PDF]

PeerJ, 2023
Soil formation by rock weathering is driven by a combination of parent material, climate, organisms, topography, and time. Among these soil-forming factors, time plays a pivotal role in the weathering of carbonatite but it is a challenging factor to ...

The circular nutrient economy of terrestrial ecosystems and the consequences for rock weathering

Frontiers in Environmental Science, 2023
Earth’s biosphere is thought to exert a substantial influence on regolith evolution and chemical weathering rates. However, ecosystems are also highly efficient at retaining and recycling nutrients.

Potassium isotope fractionation during chemical weathering of basalts

Earth and Planetary Science Letters, 2020
Non-traditional stable isotopes (e.g., Li, Mg, and Si) are increasingly used as tracers for studying Earth's surface processes. The isotopes of potassium (K), a highly soluble and mobile element during weathering, could be a promising new tracer for ...

Mobile evaporite enhances the cycle of physical–chemical erosion in badlands [PDF]

Earth Surface Dynamics, 2023
Chemical weathering driven by physical erosion is a natural process that strongly affects chemical and solid matter budgets at the Earth's surface. However, the influence of extreme climatic erosion on chemical weathering dynamics is poorly understood ...
