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.

Gabbro Description An account of the resource Samples KBR-1, KBR-2, and KBR-2A are from a vertical mass of gabbro showing progressive differentiation inward. This sample is medium grained and holocrystalline with a hypidiomorphic-granular texture. There are gray and black crystals, both ranging from <1mm- 3mm. There is a red rusty looking weathered surface. This rock has an average specific gravity. Thin section images are shown in plain and cross polarized light at40x magnification. The gabbro is composed of 65% plagioclase, 30% pyroxene, 3% oIivine, and 2% opaques. Date A point or period of time associated with an event in the lifecycle of the resource No date given.
