Title
A name given to the resource
(GC) Grand Canyon Stratigraphic Suite -- Grand Canyon, Arizona
Description
An account of the resource
This collection contains 21 samples. They are a representation of samples of lithology from the early precambrian to the late permian. The stratigraphic sequence contains a variety of rocks including, but not limited to schist, limestone, and sandstone. These specimens are representative of the geologic section in the Grand Canyon, but no specimens were collected within the boundaries of the National Park.
