Title 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. Contributor An entity responsible for making contributions to the resource Western Minerals Inc.

Title A name given to the resource (DUCO) Barrovian Metamorphic Sequence -- Dutchess County, New York Contributor An entity responsible for making contributions to the resource Western Minerals, Inc. Accrual Method The method by which items are added to a collection. Purchased from Western Minerals, Inc. Description An account of the resource A classic example of Barrovian-type metamorphism in Dutchess County, NY associated with the Taconic orogeny. A Barrovian metamorphic sequence displays gradual pressure and temperature increase along the metamorphic gradient, and occurs during regional metamorphism. These zones of pressure and temperature increase are recognizable by the characteristic minerals that accompany them. Dutchess County, NY contains an unusually complete sequence. This collection contains metamorphic rocks from chlorite grade to sillimanite grade in a tight spatial window which records the regional metamorphic gradient increasing from WNW to ESE. This collection also contains some rocks that mirror the protoliths of the schists and quartzites of the sequence (shales and graywacke).
