Abstract: Negative lineaments in the granitic bedrock areas of NW Peninsular Malaysia are interpreted to represent the strikes of fractures that have developed both before and as a result of, an approximately 120°-300° directed compression during the Upper Jurassic to Early Tertiary. The fractures pre-dating this period of compression are furthermore, interpreted to be primary fractures that have formed during the cooling of granite batholiths, particularly those emplaced during the Upper Triassic.
