Identification of ancient mantle plumes

Campbell, Ian

Description

Ancient mantle plumes can be recognized in the geologic record from uplift prior to volcanism, the orientation of dikes that feed the volcanism, the physical characteristics of the volcanism, the presence of definite age progressions along volcanic chains, and the chemistry of the magmas that mantle plumes produce. The thermal anomaly introduced by the arrival of a plume head beneath continental crust leads to widespread uplift prior to volcanism, which is followed by gradual subsidence as the...[Show more]
