Scientific paper

Major and trace element geochemistry demonstrate that the Kirkpatrick Basalt (Ferrar Group) of Antarctica, a continental flood basalt sequence, includes two distinct compositional populations, referred to as low-Ti and high-Ti flows. All basalts are relatively evolved (SiO2 = 52.7-56.7%, Mg# = 68-24), particularly the high-Ti flows which exhibit marked Fe-enrichment. Data show that the basalts carry a marked crustal signature and also have some geochemical characteristics more commonly associated with calc-alkaline rocks.
