    THE IDENTIFICATION OF COMMON ROCKS

    Quartz Quartz is a glassy looking, transparent or translucent mineral which varies in colour from white and grey to smoky. When there are individ-ual crystals they are generally clear, while in larger masses quartz looks more milky white. Quartz is hard - it can easily scratch a steel knife blade. In the rock, quartz grains are irregular in shape

    Aug 11, 2020 It is dominated by quartz, and in many cases, the original quartz grains of the sandstone are welded together with additional silica. Most sandstone contains some clay minerals and may also include other minerals such as feldspar or fragments of rock, so most quartzite has some impurities with the quartz.

    Clastic Sedimentary Rock Classification

    Oct 26, 2000 Sedimentary rocks are classified on the basis of the texture grain size of the rock, and composition. The basic classification only concerned texture, using the Wentworth size scale.But any full rock name must specify both texture and composition. Thus, an arkose sandstone is a rock of sand sized particles, with a high percentage of those particles being feldspar.
