TYPES OF SAND

The most common type of sand found in non – tropical coast and continental areas is called silica and usually takes the form of quartz. This type of sand is extremely resistant to weathering due to its chemical composition which makes the grain very hard.

White sand such as that found at the white sand National Monuments in New Mexico and on many branches around the world is composed mainly of eroded lime stone.

Green sand can be seen wherever there is a mix of basalt, chlorite and glauconitic.

Many areas in southern Europe have a deep yellow color due to concentrations of quartz and iron.
