The tectonic evolution of Antarctica ...
Five tectonic provinces; three volcanic provinces (each characteristic of a particular set of tectonic conditions) and a Precambrian shield, are outlined and described, in an attempt to illustrate the tectonic evolution of Antarctica. Evidence is presented for at least three structural stages in the...
