Abstract

Antarctic weathering of ordinary chondrites primarily affects Fe-Ni metals which are the main magnetic minerals of the meteorites. The magnetic properties of meteorites can thus be used as proxies to weathering state. The alteration products resulting from oxidation and weathering of the metals can also have magnetic properties of their own. However, the mode of weathering that operates in different environments varies, as do the products. As such, understanding how the magnetic properties are affected in Antarctica is important to recognize and understand.
