    Jurassic River Bed Sand is a unique combination of light and dark colored sand grains that eroded out of the prehistoric Rocky Mountains millions of years ago. Like many geological formations, the process was complex, varied and to a great degree, still somewhat unknown as many of the key pieces of the geological puzzle are long gone.

    Sep 28, 2020· It is observed that around 90% river bed sand particles have 600 to 212 µm particle size where 90% silica sand particle has 600 to 150 µm particle size. The particles of river bed sand are bigger than silica sand particles hence, river bed sand has less grain fineness number than silica sand as reported in Table 1.
