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 of the pyroxene is intergrown into the quartz. -Quartz (80%) -Biotite (10%) -Pyroxene (10%) -Magnification at 4x/0.10 Scanning Electron Microscope: The white power on the outside of the sample was made up of iron, calcium, silicon, aluminum, and little oxygen and carbon.

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).

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).
