This thesis presents new geochronological, thermochronological, geochemical and isotopic data from igneous and meta-igneous rock samples from the Antarctic Peninsula during the Mesozoic. This crustal block, part of West Antarctica, has a long tectonic and magmatic history, complex topography and dis...
