Description

Photo 3: A tabular dike of light-colored intrusive igneous rock (granite) cutting across dark-colored stratified metamorphic rocks (amphibolite). The granite dike formed when hot silica-rich fluid magma flowed up through cracks in the metamorphic rocks deep underground and then solidified in place. Bodies of granite occur throughout the quadrangle and exist as both larger mappable bodies (Dbg) and smaller tabular intrusions, such as shown above. Indian Point, Georgetown.
