14.1 MCMURDO VOLCANIC GROUP 3. Erebus

Fig. 16.6 (a) The Sr/ Sr ratios of Cenozoic alkali-rich lavas of the McMurdo Volcanic Group in the Erebus volcanic province have a unimodal distribution between 0.7030 and 0.7035. One sample of trachyte has an Sr/ Sr ratio of 0.70501 and a... 

The Cenozoic volcanic rocks of the Transantarctic Mountains are collectively referred to the McMurdo Volcanic Group. These rocks were erupted by volcanoes located in four volcanic provinces described in this chapter. The Erebus volcanic province includes Mt. Erebus, Mt. Terror, and Mt. Bird on Ross Island as well as Mt. Discovery and Mt. Morning on the mainland of southern Victoria Land. Volcanic rocks of Cenozoic age occur widely on the other off-shore islands as well as on Minna Bluff, the Brown Peninsula, the Royal Society Range, and the ice-free valleys.
