Title A name given to the resource (KBR) Karroo Igneous Complex -- Birds River, South Africa Description An account of the resource The Birds River Complex is a "Bell-Jar" intrusion first described by du Toit in 1905 and then by Ealey and Robey in 1976. 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.

Contact Rock Description An account of the resource This hornfels was collected from a section of contact metamorphism immediately above the dolerite of the formation from the farm Murrelfontein. It has "spots" of quartz, most likely inverted from tridymite spherulites, in a matrix of devitrified glass with mullite and cordierite. It has an aphanitic- porphyritic texture and is holocrystalline. The ground mass is light gray and anhedral, medium-grained dodecahedral brownish gray phenocrysts make up 25% of the hornfel. Some small spots of bright red iron staining (~1 mm) occur. The phenocrysts are opaque in thin section. Thin sections are shown in plain polarized light and cross polarized light at a magnification of 40x. The rock is 70% quartz and 30% opaques. The groundmass is quartz.

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 2.5x4cm white crystal formation on the upper edge of the sample. There are fractures running through the sample. There is some chemical weathering found on the outside of the sample. The chemical weathering is rust-like in color, likely indicating an oxygen and iron reaction. The sample is densely spotted with hornfels. It has a smooth texture overall. Thin Section: There are some micro-fractures with clusters of plagioclase (1~5mm in diameter). There is a single euhedral garnet crystal that is enclosed in another mineral. There are some inter growths of the matrix within some of the larger plagioclase samples. -Cordierite (50%) -Plagioclase (40%) -Quartz (9%) -Other/matrix (<1%) -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.
