文摘

U-Pb dating of zircon imply for mobility of gold at 2.71 Ga in Pampalo, Finland. Zircon show complex dissolution and recrystallization textures. Alteration and re-crystallization of zircon grains show that Zr has been mobile. Mobility of Zr is likely related the K-alteration that is related to Au mineralization.
