Phosphate Mineral Group

Comprising over 200 distinct species, these minerals are primarily characterized by the presence of the phosphate anion group (PO₄³⁻). They are commonly found in sedimentary, igneous, and metamorphic rocks, often forming as secondary minerals in the oxidized zones of ore deposits. Apatite, the most well-known and widespread phosphate mineral, is a key component of teeth and bones, highlighting the biological significance of this mineral group. Phosphates are also essential in agriculture, as they are a major source of phosphorus for fertilizers, which are critical for plant growth. Beyond their practical uses, some phosphate minerals, like turquoise, are valued for their vibrant colours and are used as gemstones and ornamental stones.
