Systematic Covariation of Sr, Ba, Ca elements in Cenozoic Volcanic Rocks on the Fildes Peninsula, West Antarctica, and its relation to Petrogenesis
Cenozoic volcanic rocks in the Fildes Peninsula are composed of High-Al basalt, basaltic andesite, andesite, and dacite belonging to a calc-alkaline volcanic series with low-K and high-Al characteristics. Using a new indicator, the Sr / Ca-Ba / Ca, systematics proposed by Onuma (1989,1981) and Sr, B...
