Anisotropy of Magnetic Susceptibility (AMS) measurements on geological samples from the Theron Mountains, Antarctica, collected 2004-2005
Laboratory AMS (Anisotropy of Magnetic Susceptibility) measurements made on a collection of sill samples collected from the Theron Mountains, Antarctica, during the 2004-2005 field season.
AMS involves the collection of some 1 metric tonne of oriented samples and the lab-based determination of the magmatic flow fabric of the rock. Models concerning the location of mantle plumes and triple junctions associated with the Mesozoic break-up of Gondwana in the Antarctic-southern Africa sector are not capable of independent testing, other than by geochemical and age dating methods. We determined the regional flow directions of the magmas in dyke and sill complexes in the areas of postulated plume heads and related triple points on the opposing conjugate margins. AMS was utilised to determine magmatic flow directions and constrain these with macroscopic observations of flow indicators.
