Biogenic Sand is a kind of sand that contains tiny particles of skeletal material, seashells, and corals, etc.
Garnet sand is a type of sand that contains garnet which is a mineral as its major component.
Olivine sand is a type of unstable land which is generally used for steel casting works.

Heavy mineral sand is sand that consists of molecules of high mass and it is used for forming stable structures.
Continental sand is a type of sand that is generally found on continental beaches and light brown in colour in which some dark grains sparkled.
