(Table 1) Detrital modes for sand grains in sediment core CRP-3, supplement to: Smellie, John L (2001): History of Oligocene erosion, uplift and unroofing of the Transantarctic Mountains deduced from Sandstone detrital modes in CRP-3 drillcore, Victoria Land Basin, Antarctica.

John L Smellie
Detrital modes determined on 68 sandstone samples from CRP-3 drillcore indicate a continuation of the dynamic history of uplift-related erosion and unroofing previously documented in CRP-1 and CRP-2/2A. The source area is identified very strongly with the Transantarctic Mountains (TAM) Dry Valleys block in southern Victoria Land. Initial unroofing of the TAM comprised removal of much of a former capping sequence of Jurassic Kirkpatrick basalts, which preceded the formation of the Victoria Land Basin. Erosion...
