More than 500,000 line-km of new airborne and shipborne data recently acquired by the international community over East Antarctica and surrounding regions significantly upgrade the ADMAP compilation, and provide substantial improvements in outlining magnetic anomaly patterns. New data have been matched in one inverse operation by minimizing the data differences for the areas of overlap. Aeromagnetic data over the continent allow recognizing many unknown magnetic patterns, lineaments and trends and help determine spatial extent of Ferrar volcanics and plutonic Granite Harbour Intrusives in the Transantarctic Mountains and previously unknown tectonic trends of the East Antarctic craton. Regional aeromagnetic investigations have been successful in delineating Early Paleozoic inherited crustal features along the flanks of the West Antarctic Rift System and in defining the southern boundary of the Archean Ruker Terrane in the Prince Charles Mountains. Magnetic records along the East Antarctic continental margin provide new constraints on the breakup of Gondwana.
