East Asian monsoon- and ENSO-regulated chemical weathering on North Thailand during the middle-late Holocene: Records from clay mineralogy and major element geochemistry in the Gulf of Thailand

Key Points

• Chemical weathering in North Thailand varied with climatic factors during the Holocene, indicating strong environmental influence.
• Key relationships between clay mineralogy, major element geochemistry, and climatic changes were observed, establishing connections to monsoon activity.
• Observational analysis of sediment samples from the Gulf of Thailand reveals insights into historical climatic patterns affecting chemical weathering processes.
• These findings highlight the need for further exploration of long-term climatic effects on regional geochemistry.
