It is found in association with fluorapatite, wavellite, phosphosiderite, strengite, aldermanite, cacoxenite, variscite, turquoise, fluorite and quartz.
2.
A complete series exists from lithiophilite, LiMn 2 + PO 4 to triphylite, LiFe 2 + PO 4, including hureaulite, strengite, FePO 4 ?H 2 O, stewartite, Mn 2 + Fe 3 + 2 ( OH, PO 4 ) 2 ?H 2 O, and sicklerite, ( LiMn 2 +, Fe 3 + ) PO 4.
3.
In the tropics, rather than taranakite, the minerals that form from guano-derived phosphatization of igneous rocks are variscite ( AlPO 4 ?H 2 O ), metavariscite ( AlPO 4 �H 2 O ), barrandite ( ( Al, Fe 3 + ) PO 4 ?H 2 O ), strengite and phosphosiderite ( Fe 3 + PO 4 ?H 2 O ).
