Sintesi geologica
A large number of basaltic cinder cones and lava flows are located in the Royal Society Range of southern Victoria Land. Most vents are of Quaternary age. More than 50 basaltic vents, ranging from tiny scoria mounds to cinder cones up to 300 m high, occupy the foothills. Tephra layers in the ice of Kempe Glacier, K-Ar ages as young as 80,000 years old, and well-preserved geomorphic forms, all argued for young, possibly even Holocene ages (LeMasurier and Thomson, 1990).
