Title A name given to the resource (PH) Powderhorn (Iron Hill) Carbonatite Suite -- Gunnison County, SW Colorado 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 (TMJ) Quartz-rich Metamorphic Suite -- Tanzawa Mountains, Kanto, Japan Description An account of the resource The Tanzawa Mountains in Japan were created in an arc-arc collision, when the Izu-Bonin-Mariana Arc was subducted beneath the Honshu Arc. This eventually accreted into the Tanzawa Mountains. The samples in this collection were found in and around the Tanzawa Mountains. The suite includes hornfels, amphibolites, quartz diorite, granophyres, and other basaltic rocks. The samples range from fine to coarse grained. An interesting feature found on many of the samples was a flow-like swirl of minerals in the thin section, visible in XPL. The quartz diorite samples had crystalline, powdery substances on them, which were analyzed using a Scanning Electron Microscope (SEM). The chemical compositions of the mentioned powdery substances were calcium, aluminum, silicon, and oxygen.

Some parts of the rock exhibit greasy luster. There are some tannish white spots and some slightly larger dark brown spots. The tannish white mineral reacts with acid. There are dark green and faded dark green phenocrysts(~3mm in size). There are medium to coarse grained white phenocrysts (2-10mm). Some phenocrysts touch each other with no matrix in between. There are some areas that possess a dark grey matrix. There are many fractures through out the sample. It has a rough and bumpy texture overall. Thin Section: There are many micro-fractures and veins. There are many larger fractures as well. There are also circular crystals that have a pointed center. Some of the augite crystals are severely fractured, and have quartz veins running through the fractures. There are many elongated quartz crystals that are curved. There is some glass intergrown into the circular crystals. -Matrix (55%) -Augite (25%) -Quartz (10%) -Plagioclase (10%) -Magnification at 4x/0.10 Date A point or period of time associated with an event in the lifecycle of the resource 1969 Contributor An entity responsible for making contributions to the resource Western Minerals, Inc.

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.

Purchased from Western Minerals Inc. Description An account of the resource This specimen consists of 50-60% andesine, 20-30% quartz, and minor pyroxene and hornblende. Associated with this lithology are 2-6 inch layers of pyroxene-plagioclase granulite and amphibolite. It is believed that the Royal Mountain Member gneiss represents a metamorphosed layered instrusion of overall tonalitic composition. Numerous internal features, such as xenoliths and possible slump structures, support this hypothesis. Thin section shows plagioclase, quartz and hornblende.

Title A name given to the resource (PH) Powderhorn (Iron Hill) Carbonatite Suite -- Gunnison County, SW Colorado 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.
