Kind sorts earth materials into their broadest category, such as mineral, rock or sediment. Wikipedia describes quartz as "a hard mineral composed of silica (silicon dioxide)," placing it firmly in the mineral kind rather than among rocks made of many minerals together. This dimension gives a visitor the widest possible grouping of what a material actually is.

Phosphate minerals are minerals that contain the tetrahedrally coordinated phosphate (PO3-4) anion, sometimes with arsenate (AsO3-4) and vanadate (VO3-4) substitutions, along with chloride (Cl-), fluoride (F-), and hydroxide (OH-) anions, that also fit into the crystal structure.
