Immature lithic sand from silcrete deposit containing clear rounded quartz, jagged clear quartz, orange gypsum, calcium rich siltstone, chips of purple quartzite, goethite. Notable absence of silcrete as it highly resistant to weathering.
This sample was taken near a copper rich siltstone area. It contains predominantly quartz, with some sandstone, siltstone and possibly garnets.
