Magnetite is a common mineral with thousands of localities worldwide It is “a common accessory mineral in igneous and metamorphic rocks in which magmatic segregations or contact metamorphism may produce economically viable deposits [as well as] in sedimentary banded iron formations, [as] a biogenic product, [and in] important detrital.

Most magnetite grains in sand are rounded but some show characteristic octahedral morphology It is never elongated because of cubic (isometric) crystal system Magnetite is common in sand because it is abundant in many rock types and it is also moderately resistant to weathering.
