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.

The distinction between titles and alternative titles is application-specific. Ferrotholeiite Description An account of the resource The intersertal ferrotholeiite samples are highly fractionated and were most likely emplaced before the gabbro of the formation. They have textures associated with rapidly frozen or highly viscous melts. KBR-8 through KBR-11 are also intersertal ferrotholeiites. Intersertal is a texture marked by the occurrence of interstitial glass between laths of feldspar, usually in basalts. Between the location this sample was collected and KBR-6 was collected, there is a thin gabbro pegmatite which was not collected. It has an aphanitic porphyritic texture and is holocrystalline. It has a consistent dark gray color with fine veins of quartz < 1mm wide. There are medium grained subhedral plagioclase phenocrysts ( 2mm - 5 mm). There is a calcic residue on heavily oxidized weathered surface. A subophitic micro-texture is also present. Spherulitic pyroxenes are clearly visible in cross polarized light. Thin sections are shown in plain and cross polarized light at 40x magnification. The rock is composed of 40% plagioclase, 40% pyroxene (mainly augite), 10% biotite, 5% olivine, and 5% opaques.

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.

The distinction between titles and alternative titles is application-specific. Ferrotholeiite Description An account of the resource The intersertal ferrotholeiite samples are highly fractionated and were most likely emplaced before the gabbro of the formation. They have textures associated with rapidly frozen or highly viscous melts. KBR-7 through KBR-10 are also intersertal ferrotholeiites. Intersertal is a texture marked by the occurrence of interstitial glass between laths of feldspar, usually in basalts. It has an aphanitic porphyritic texture and is holocrystalline. It has a consistent dark gray color and contains fine veins of quartz <1mm wide. There are medium grained subhedral plagioclase phenocrysts (2 mm- 5 mm). There is a calcic residue on a heavily oxidized weathered surface. There is a subophitic micro-texture. Radiating pyroxenes are clearly visible in plain polarized light. Thin sections are shown in plain polarized light and cross polarized light at 40x magnification. The rock is comprised of 65% plagioclase, 30% pyroxenes (mainly enstatite), and 5% opaques.
