Constraints on metamorphic and ore forming conditions of the lukkulaisvaara layered intrusion, oulanka group intrusions, northern karelia, Russia

摘要

Within the Lukkulaisvaara massif the redeposition of precious metals took place at a temperature of 320-450 deg and with P=1.5-2.5Kbar. The source of the fluid could be a new portion of magma which may have induced a stress of P_m=9-12 kbar in the country rocks during its emplacement.
