Formation of smectite from weathered Archean rocks

Key Points

• Smectite forms as a result of complex weathering processes in Archean rocks, revealing insights into ancient minerals.
• The analysis identifies key geochemical processes and conditions that facilitate mineral formation from primary rock materials.
• Observational analysis highlights multiple stages of weathering, showing the transition from original minerals to smectite.
• Understanding these processes may enhance knowledge of mineral evolution and the Earth's early conditions.
