Title A name given to the resource (SFM) Igneous Suite -- St. Francois Mountains, Southeastern Missouri Description An account of the resource This collection is composed of igneous volcanic and intrusive rocks from the St. Francois Mountains of Missouri. The variation within the collection can be used to explain the geologic history of the area. The St. Francois Mountains batholith was formed by granitic intrusions into Precambrian rhyolites, tuffs, and breccias. Then basalt, diabase, and porphyritic intrusions cut the granitoids.

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.

One of the best exposed sections across the margin of the complex is on the farm Denwood, in the southwestern corner of the complex. The samples were collected from a mafic intrusion near Denwood farm. These samples from the Karroo Complex were collected from the previously studied section of the complex and neighboring areas.

Diabase or Microgabbro Description An account of the resource This is dolerite from the "Dragon's Back" dyke, from the farm Romance. It is the youngest dolerite body in the area and contains biotite and hornblende. Emplacement of this dolerite took place at a much deeper crustal level than the gabbros. It has an aphanitic- porphyritic texture and is holocrystalline. The groundmass is light gray and subhedral. It contains slightly darker gray fine grained subhedral phenocrysts that comprise 30% of the dolerite. There is pinkish- brown blotchy weathering. The thin sections are shown in plain polarized light and cross polarized light at a magnification of 400x and contains 60% plagioclase, 35% pyroxenes, and 5% opaques.

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.

Dolerite Description An account of the resource Rock Sample: The rock is dark green throughout, with a mineral forming white specks. The white mineral does not react with hydrochloric acid. The texture is very rough, and the rock's edges are sharp. Large flat phenocrysts (~ â‰¤10mm). The sample is non-foliated and has an aphanitic matrix. There is a off-white colored crystal forming on one of the faces. They are bumpy and <0.1mm in depth. There is some minor 70 degree cleavage on the sample. Thin Section: There are micro-fractures, and many of the minerals have a blue-green tint in PPL. There are also larger fractures throughout the thin section. The sample is holocrystalline with some brown glass-like blotches. There is a poikilitic texture while viewed in XPL. -Augite (~30%) -Plagioclase (~60%) -Olivine (5%) -There is little to no quartz -Magnification at 4x/0.10 Scanning Electron Microscope: The light green filament on the face with the label is composed of iron, calcium, silicon, aluminum, magnesium, sodium, oxygen and small amounts of carbon.
