Rb-Sr dating of Asgard Formation rocks from the Lower Wright Valley and Victoria Valley to determine the age of the oldest basement rocks in the Ross Dependency
Entry ID:
K231_1985_1986_NZ_1
Summary
Abstract:
A programme was conducted to determine the age of the oldest basement rocks in the Ross Dependency. The Asgard Formation in the Dry Valleys is a series of metamorphosed sedimentary rocks that form the oldest basement in this sector of the Transantarctic Mountains. Two weeks were spent in the Lower Wright Valley (near the Meserve Glacier Hut) and Victoria Valley (near Lake Vida) covering on foot ...
