Basement Collection
Basement rocks are igneous and metamorphic rocks, largely Precambrian in age. They form part of the continental crust and are often deeply buried by younger sedimentary rocks.
"Buried basement rocks of the United States of America and Canada" was a study completed by a group of geologists in 1964. It was headed by William R. Muehlberger
(Jackson School of Geosciences).
Rock samples, mineral separations and thin sections used to complete the study are held in this repository.
