Inclusions of foreign rocks that are found in igneous rocks are named xenoliths. So we can also say that kersantite contains xenoliths of granite. The same principle is also used in relative dating of sedimentary rocks. WebThe dark line around the xenoliths is amphibole, which formed as the olivine reacted with the melt.
