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.

(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.

Description
An account of the resource
Collected from the Redwall Formation, this is a highly silicious sample defined in the suite's documentation as chert, but the sample lacks the nano-crystalline appearance of a traditional chert. It appears to be more of a slightly metamorphosed quartzose sandstone.
Modal Abundances:
Quartz (95%)
Matrix (5%)
Both thin section images were taken at a 400x magnification.

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.

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.

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.
