Abstract
On the western edge of Antarctica a rift basin has been forming since the Jurassic
Period. This is a complex area with several types of faulting as well as magmatic
intrusions. The data collected thus far has shown the Victoria Land Basin to contain four
spreading centers that have thinned the crust and allowed magmatic traces to surface. The
purpose of this study is to determine whether the volcanics caused the rifting or if the
rifting provided a pathway for the magma to work its way up to the surface. This theory
will be tested by examining the shape and pattern the magmatic centers represent.
