  • Hematite Sand - Sandatlas

    Hematite Sand - Sandatlas

    Hematitic sand and sandstones are mainly consisting of quartz but these quartz grains have an intense pink, orange or red color. The coloring agent in this sand is volumetrically insignificant – it is hematite (oxide of iron) that forms very thin rust-colored pigment on larger silicate grains.. However, its influence on the appearance of sand or sandstone is very strong
