A name given to the resource
(ADK) Anorthosite-Charnockite and Metamorphic Suite --
Adirondack Mountains, New York
Description
An account of the resource
The Adirondack Mountains of northern New York State are underlain by approximately 20,000 square miles of complexly deformed, high grade metamorphic rocks which are believed to represent a southern outlier of the much larger Grenville Province.The Adirondacks can be divided into the "Lowlands" and the "Highlands" . The Lowlands comprise the northwestern quarter of the belt and are characterized by amphibolite facies metamorphism. The Highlands appear to consist entirely of granulite facies rocks. All rocks in this suite have been collected from the Highlands and predominantly from the southern quarter of the Adirondacks.
This suite of rocks is designed to be representative of the Highlands in general. Therefore it includes both metasedimentary and metaigneous rocks. The latter are very common throughout the Adirondacks and contain the often-discussed anorthosite-charnockite suite of rocks. Almost all rocks in the Adirondack Highlands are strongly foliated. This is the result of intense polyphase deformation that has affected this area.

Description
An account of the resource
The locality near Northville, NY represents the only example of this assemblage that has been encountered to date (1980) in the Adirondacks. The original lithology is that of a typical olivine metagabbro. During granulite facies metamorphism, reactions produced coronas consisting of orthopyroxene rims on olivine and spinel-clinopyroxene symplectites. Amphibole-spinel coronas also occur. These assemblages appear to represent lower pressure conditions than prevailed during the formation of the garnet-bearing assemblages represented by AD-16.
The following information is from the original OCR document: The mineralogy and textural features of these metagabbros are discussed in McLelland and Whitney, 1980, Contributions to Mineralogy and Petrology, v.72, p.111, specimen 17 and Whitney and McLelland, "Origin of Coronas in Olivine Metagabbros of the Adirondack Mountains, NY," 1973, Contributions to Mineralogy and Petrology, v. 39, p.81-98. The specimen you receive may be somewhat smaller than the regular specimens. Dr. James McLelland collected this material especially for this suite-and in 100° temperature. Thank you, Jim.
Thin section shows augite, spinel and plagioclase.

Description
An account of the resource
The Sacandaga Formation consists of a well layered series of dark granulites (AD-12) and leucogneisses (AD-13). Orthopyroxene is generally present in greater quantity than clinopyroxene. It is not known whether these rocks are metasedimentary or metaigneous. They are strongly foliated.
Thin section shows plagioclase (one with perthitic texture), orthopyroxene and quartz.

Description
An account of the resource
The Powderhorn (Iron Hill) Carbonatite is located in Gunnison County in about the center of the southwestern quadrant of Colorado. It is a pear-shaped body which is essentially conical at depth, and is exposed over an area of about 12 square miles. The carbonatite body covers about 2 and a half square miles; About 70 percent of the in pyroxenite which was subsequently intruded by or replaced by nepheline and melilite-bearing rocks; magnetite-perovskite, and carbonatite.

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.
