Geochemistry of subvolcanic zoned granitic pluton in the Barton and Weaver Peninsula, King George Island, Antarctica / Jong Ik Lee, Soon Do Hur, Moon Young Choe, Chan Min Yoo, Keisuke Nagao.

Title: Geochemistry of subvolcanic zoned granitic pluton in the Barton and Weaver Peninsula, King George Island, Antarctica / Jong Ik Lee, Soon Do Hur, Moon Young Choe, Chan Min Yoo, Keisuke Nagao.

In: Proceedings of the joint international seminar Recent Interests on Antarctic Earth Sciences of Korea and Japan. (2001.),
Abstract: Describes petrological and geochemical characteristics of subvolcanic pluton, and discusses origin of vertical zonation of pluton and primary magma composition. Pluton is mainly composed of granodiorite with small volume of gabbro, diorite quartz monozodiorite and aplitic dikes, and shows vertically compositional zonation with lower part consisting of gabbro and diorite, and upper part mainly grandiorite. Geochemical signatures confirm that all subunits were formed by accumulation and fractionation in calc-alkaline magma at shallow level of crust. Positive Sr and Eu anomalies, and textural features of gabbro, suggest that it was cumulate derived from calcic plagioclase and in situ crystallization of ferromagnesian minerals, and that primary magma of pluton was intermediate (dioritic or quartz dioritic) in composition. Includes analytical result of major, trace and rare earth elements of granitic rocks.
