- •
Episyenites in the Bohus granite were mainly developed during two separate stages.
- •
The initial stage of quartz removal and albitization is related to the cooling of the host granite.
- •
A subsequent reactivation occurred during the development of the nearby Oslo Rift.
- •
The mineral 未18O and 未D data exhibit a general isotopic disequilibrium.
- •
The fluids involved during reactivation resemble the modern-day shield brines.
