Koru (Tahtalıkuyu et Eskikışla)
Çanakkale (Lapseki), Biga Peninsula, Turkey
Epithermal depositsPb-Zn (Ba)
- Type
- Barite-bearing Pb-Zn veins and stockwork in Tertiary pyroclastics
Barite-bearing Pb-Zn deposit in the Oligocene Adadağı pyroclastics, as stockwork in its upper part and as WNW-ESE veins at depth. Fluid inclusions from 120 to 270 °C. Sulfide sulfur close to 0 ‰ (volcanic components), barite sulfur from Tertiary marine sulfate; lead leached from Eocene to Quaternary volcanic and volcano-sedimentary rocks by meteoric water. Indicative coordinates.
