Geochemistry and U–Pb Zircon Geochronology of Granite at the Pilok Sn–W Deposit, Thailand: Implications for Late Triassic Tin Metallogenesis

open access: yesResource Geology, Volume 76, Issue 1, January‐December 2026.
Zircon U–Pb dating constrains the Pilok Sn–W granite emplacement at 212–208 Ma, during the Late Triassic post‐collisional extension after the Sibumasu‐Indochina collision. This timing coincides with widespread tin‐bearing granite magmatism throughout Southeast Asia, marking a major regional metallogenic event. ABSTRACT The Pilok Sn–W deposit in western
