Three Lower Tertiary volcanic complexes occur at the Turred Point-Mersey Spit promotory on King George Island (South Shetland Islands, West Antarctica. The first complexis represented by a pile of thick andesitic-basaltic lava flows attributed to the Mazurek Point Formation. The second complex consist of andesite breccias which from vertical cutting the lavas. The third complex is represented by vertical andesite plugs and dykes cutting the lavas and the vent braccias.
