Tilting is situated on the northeast corner of Fogo Island which lies off the northeast coast of Newfoundland. Fogo Island has an area of approximately 110 square miles and the Tilting area which encloses the settlement of Tilting has an area of approximately 5 square miles. Many diverse rock types occur within the Tilting area where a diorite gabbro complex is intruded by the Fogo granite batholith. -- In several places the basic rocks of the diorite gabbro complex show marked primary banding accompanied by primary foliation. The writer feels that this primary banding originated through rhythmic differentiation and that the primary foliation is a sedimentation structure. A review of the literature and description of classic areas are presented. -- Intrusion breccias and gradational rock series are of common occurrence. Hybrid rocks characterized by abnormal mineral associations are discussed.
