Sandstone dikes occur along the northeastern contact zone of the Pikes Peak batholith in the South Platte area, Colorado. The dikes range in width from a few inches to more than 10 feet and in length from a few feet to more than 8 miles. They are closely associated with faults occurring in the crystalline rocks of the area. It is proposed that these dikes were formed by injection of clastic material from above along submarine faults during Cambrian times.
