Karelian Gold Line
Description of Gold Deposits
Endomines Oy operates in the Karelian Gold Line in eastern Finland.
The Karelian Gold Line mineralisations are of Archaean age meaning that they were formed more than 2 500 million years ago. Usually gold is found as individual grains or together with sulphides, oxides or tellurides in quartz veins, breccias or shear zones. These orogenic mineralisations are considered to be formed so that gold has leached out from the surrounding bedrock during intensive shearing and precipitate again in structural traps doe to the changes in the pressure and temperature.
