PETROLOGY AND GEOCHEMICAL COMPARISONS OF THE QUATERNARY VOLCANIC ROCKS FROM LIVINGSTON ISLAND, ANTARCTICA

Late Cenozoic mafic alkaline volcanic rocks occur through-out the entire Pacific coast of West Antarctica, including some of the islands adjacent or within the Bransfield Strait. Amongst them, Livingston Island is the least well-known, particularly in respect to mineralogy, petrology and geochemistr...

Description
Summary:Late Cenozoic mafic alkaline volcanic rocks occur through-out the entire Pacific coast of West Antarctica, including some of the islands adjacent or within the Bransfield Strait. Amongst them, Livingston Island is the least well-known, particularly in respect to mineralogy, petrology and geochemistry of the scarce manifestations of this type rocks, known as Inott Point Formation. This contribution presents new major element and trace element data from old and new-discovered outcrops in Livingston Island and compares them geochemically with simi-lar rocks from the island Greenwich situated in South Shet-land Islands arc and with Quaternary basalts in the islands Penguin, Deception and Bridgeman, within the back-arc rift basin Bransfield Strait. Alkaline basalts from the provinces in
