Popis:	Excellent exposures along the coast of Labrador for 150 km. reveal a consistent pattern of thick gabbro sheets overlying migmatic granite gneisses. The relationship between the two rocks is complex, and in many places each appears to have intruded the other. However, mineralogical, textural, and structural criteria may be interpreted as showing that the gabbros are younger than the gneisses. An exceptional example illustrating these relations is described from Spotted Island. It is suggested that the heat of the intruding gabbro magma caused widespread mobilization of the granitic basement rocks.
