Fluid evolution from quartz veins in micaschists from the thermal aureole around the Acari batholith, Northeast Brazil
Micaschists that host the Acari batholith (Ediacaran age, 572 to 577 My) are characterized by a large number of quartz veins. The veins are more abundant in higher-temperature metamorphic zones and, together with lower metamorphic zones, form an aureole centered in the batholith. Most of the fluid...
