Phosphate minerals are minerals that contain the tetrahedrally coordinated phosphate (PO 3− 4) anion, sometimes with arsenate (AsO 3− 4) and vanadate (VO 3− 4) substitutions, along with chloride (Cl −), fluoride (F −), and hydroxide (OH −) anions, that also fit into the crystal structure.
Glaucophane is a mineral and a mineral group belonging to the sodic amphibole supergroup of the double chain inosilicates, with the chemical formula Na 2 (Mg 3 Al 2)Si 8 O 22 (OH) 2. Glaucophane crystallizes in the monoclinic system .
The name mineralocorticoid derives from early observations that these hormones were involved in the retention of sodium, a mineral.The primary endogenous mineralocorticoid is aldosterone, although a number of other endogenous hormones (including progesterone [1] and deoxycorticosterone) have mineralocorticoid function.
