    www.sciencedirect.com/science/article/pii/S1464343X20302259 Churchite from the GBO unit of the Badamlu bauxite deposit is characterized by low contents of Gd (2.0–3.5 wt%) and Dy (3.8–6.4 wt%), and Ce, Nd, and Er were not detected. This indicates that chuchite in the Badamlu bauxite deposit is of churchite-(Dy) type.

  • Phosphate mineral - Wikipedia

    en.wikipedia.org/wiki/Phosphate_mineral Phosphate minerals contain the tetrahedrally coordinated phosphate (PO 4 3−) anion along sometimes with arsenate (AsO 4 3−) and vanadate (VO 4 3−) substitutions. Chlorine (Cl −), fluorine (F −), and hydroxide (OH −) anions that also fit into the crystal structure.. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.
