Although other metallic minerals may mimic magnetiteâs color, luster, hardness and specific gravity, magnetite is the only common mineral that is magnetic. So a magnet is usually all that is needed to identify its presence. Magnetite crystals usually only occur when magma cools slowly enough for crystals to form and settle out of the magma.
A mineral is a naturally occurring crystalline material that has a specific or limited range of chemical compositions. Clay minerals have a sheet-like structure and are composed of mainly tetrahedrally arranged silicate and octahedrally arranged aluminate groups.Kaolinite is the principal mineral in kaolin clays.It is a 1:1 clay mineral â the basic unit is composed of a 2-dimensional (2D) layer of silicate groups tightly bonded to a 2D layer of aluminate groups. mineral is a naturally occurring crystalline material that has a specific or limited range of chemical compositions.
