Geology
AlterationThe area is underlain by hydrothermally altered Mesozoic graywacke and argillite (Reed and others, 1978). Alteration mineralogy is not specified. However, based on its reported similarity to altered zones at Thunder Creek (TL032, TL058), it is most likely argillic alteration of Mesozoic sedimentary rocks.
