The Xiashu Loess in the lower Changjiang River area has undergone strong chemical weathering, with elements like Ca, Sr, Na, and Mg being leached out. Both carbonates and silicate minerals in the Xiashu Loess have experienced rapid weathering, especially plagioclase. The weathering patterns of the Xiashu Loess are similar to those of loess in Northwest China, indicating similar weathering processes. The strong chemical weathering in the Xiashu Loess is likely due to the intense monsoon climate in the lower Changjiang River region.
