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.

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.

There is a lime green layer as well as some dark grey and brown groupings. It is pegmatic and experiences non-congruent foliation and Y-shaped fractures. There are dark brown to orange areas which indicate that chemical weathering took place. The sample has silty or sandy texture. In some spots around the sample there is a thin layer <0.1mm that resembles fine grained sandpaper in texture and color. It does not react with hydrochloric acid. Some of these "spots" are imbedded ~0.2mm in the exterior of the sample. Thin Section: There are micro-fractures in non-uniform formations. Also there are thick veins of quartz. The sample is hypocrystalline with fine grained size glass.

Some parts of the sample are a more dark turquoise. Some faces are lighter and or darker than other faces. There is also a face with a brownish color and another face with a tannish color. The majority of the sample feels silty/sandy but there is one face that feels waxy. There are coarse grained blue-green phenocrysts, ranging in size of (2-8mm). Some of the phenocrysts are white linear phenocrysts (≤10mm in length). The matrix is apharitic. The sample experienced minor chemical weathering with some orange to brown blotches. This may have been due to oxidation. Some erosion took place on the sample, creating crater-like hole on the sides of the sample.<br /><br />Thin Section:<br />PPL.

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.

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.

Title A name given to the resource Basaltic Tuffaceous Conglomerate Description An account of the resource Rock Sample: The overall matrix is a dark green blue but there are many different colored clasts that give it a mixture of colors. The color of the clasts range from brick red, pink, white, and green (non-reactant to acid). The texture of the rock is silty. There are massive, very coarse grained clasts that are up to 3cm in length. There are clasts within other clasts. There is one fracture spanning across the rock. There is evidence of minor chemical weathering. The overall shape of the rock is an octahedral. It has eight faces and forms into a jagged ball. Thin Section: The matrix has many globular, navy blue crystals, with an outer shell around them (XPL). Some plagioclase crystals experience tartan twinning. Also, some of the plagioclase is intergrown within other plagioclase crystals. The matrix has a variety of colors in XPL (navy blue, yellow, and brown in various shades), and makes up the majority of the thin section. There are some smaller dark blue crystals that are in the shape of a half spoked wheel (under XPL). There are some very fine grained sized glass crystals within the thin section. -Plagioclase (50%) -Quartz (20%) -Pyroxene (10%) -Olivine (10%) -Biotite (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 (FM) Flysch Stratigraphic Suite -- Molasse Basin, Switzerland Description An account of the resource Flysch is dominantly a turbidite succession, alternating sandstone and shale 100mm to rarely 100m in syntectonic accumulations. With a rising landmass shedding clastic debris into "deep" troughs, oversteepening of sediments along the shelf or actual tilting of the shell initiated turbidity currents flows deeper into the marine basin. There may be hundreds of these units in a given section. Nappes then over rode the soft sediments, locally producing strong deformational structures in the flysch sediments. <br /><br />The nappes shed their debris into fresh marine environments in great fans with large accumulations of coarse conglomerates. A molasse section may be a thousand meters thick. Molasse comprises a clastic sedimentary succession in a post-tectonic environment. <br /><br />Flysch and molasse both have sedimentatlogical as well as tectonic implications associated with their appearance in an outcrop.  <br /><br />Dr. Trumpy at the Geological Institute in Zurich suggested specific localities for collecting and arranged for Dr. Hanspeter and Mr. Freeman to take me into the field on successive days.

Title A name given to the resource (FM) Flysch Stratigraphic Suite -- Molasse Basin, Switzerland Description An account of the resource Flysch is dominantly a turbidite succession, alternating sandstone and shale 100mm to rarely 100m in syntectonic accumulations. With a rising landmass shedding clastic debris into "deep" troughs, oversteepening of sediments along the shelf or actual tilting of the shell initiated turbidity currents flows deeper into the marine basin. There may be hundreds of these units in a given section. Nappes then over rode the soft sediments, locally producing strong deformational structures in the flysch sediments. <br /><br />The nappes shed their debris into fresh marine environments in great fans with large accumulations of coarse conglomerates. A molasse section may be a thousand meters thick. Molasse comprises a clastic sedimentary succession in a post-tectonic environment. <br /><br />Flysch and molasse both have sedimentatlogical as well as tectonic implications associated with their appearance in an outcrop.  <br /><br />Dr. Trumpy at the Geological Institute in Zurich suggested specific localities for collecting and arranged for Dr. Hanspeter and Mr. Freeman to take me into the field on successive days. Later, Mr. Freeman spent several days in order to procure this suite. <br /><br />A set of kodachrome slides is available and should be used with the specimens to put the rocks into relationships seen in the field.
