文摘
- •
Analysis of U-series isotopes and in situ 10Be in a single regolith profile.
- •
Independent determination of long term regolith denudation and production rates.
- •
Lower regolith is the most suitable place to quantify regolith production rate.
- •
A high spatial resolution profile is required for an extensive modeling of in situ 10Be.
- •
Higher temporal variability of physical erosion than chemical weathering.
