Abstract
That remobilization of sulfide veins can occur in nature seems indicated by observations in the Coeur d'Alene district of Idaho. There is evidence of local remobilization in the vicinity of post-ore dikes. In one mine the shapes and limits of oreshoots reflect modification by the intrusion of a large stock. A theoretical discussion of 4 possible mechanisms for remobilization follows: A) Engulfment of old veins by invading magma; B) remobilization by hydrothermal dissolution and redeposition; C) remobilization by heat and gases from nearby magma; and D) tectonic remobilization.
