Abstract: Volcanic geological, petrological and geochemical characteristics of the Tertiary volcanic rocks from the Fildes Peninsula, West Antarctica show that magma evolution was a process of dissipation of heat energy exchanged energy and mass occurring between the magma system and its surrounding environments, and with the feature of dynamic equilibrium and periodicity (stage). In the study volcanic rocks of different types commonly exhibit a multi-grade composite texture and the derivative magmas produced by differentiation of parent magmas in the magma chamber show a zonal structure in the high-level-magma chamber which represent self-organization phenomenon of the nonequilibrium process in magmatism. The self-organization phenomenon is dissipative structure formed under given conditions.
Keywords: West Antarctica, Fildes Peninsula, magmatism, self-organization phenomenon
