  • Silica sand sandatlas

    Such sand deposits are said to be mature because other rockforming minerals are already broken down by the weathering process leaving only the superresistant quartz as a residue. Silica sand is a mineral resource. It is mined mostly for glassmaking. Another major use of sand is a concrete production but that does not need sand to be as pure.

  • Rounding of Quartz and KFeldspar Sand From Beach to Dune

    Quartz and Kfeldspar are common minerals in most sedimentary settings, both modern and ancient. The minerals are easily distinguished under the petrographic microscope when the sample has been stained for Kfeldspar (leaving quartz white and making Kfeldspar yellow). While studying the petrology of some ancient sandstones, we became interested in the rate at which Kfeldspar sand grains were rounded in comparison with quartz sand grains in natural settings. In this preliminary study, we colGet Price
