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.

Biotite - Plagioclase - Quartzite Description An account of the resource Rock Sample: The sample has black to green phenocrysts with a greenish white matrix. It has phaneritic grains with a aphanetic matrix. Phenocrysts are coarse to fined grained ranging from 0.1~1cm in size. There is a chalk like powder on the outside of the sample (white). There are deep fractures running to the center of the sample. It is likely that the sample underwent chemical weathering by oxidation. The chemical weathering is evident due to the orange brown tint. Overall the sample has a smooth weathered outside with rough gritty inside. Thin Section: Minerals are either medium in size. All the minerals seem to have intergrown in the quartz crystals. -Quartz (50%) -Plagioclase (20%) -Biotite (15%) -Hornblende (15%) -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.
