Summing up their work on Sapucaia phosphates, Lindberg and Pecora (1958) listed their apatite, bermanite, childrenite, gordonite, heterosite, hureaulite, leucophosphite, lipscombite, metastrengite (= phosphosiderite), montebrasite, roscherite, saleeite, strengite, triphylite, variscite and vivianite as having been positively identified, in addition to the new species.
The frondelite assemblage consists of residual heterosite, [TABULAR DATA FOR TABLE 1 OMITTED] montebrasite and triphylite enclosed by frondelite; massive replacement of frondelite by cyrilovite, cryptomelane and leucophosphite; and fracture coatings in frondelite of bermanite, cyrilovite, goethite, leucophosphite, lipscombite, mitridatite, moraesite, opal, phosphosiderite, rockbridgeite, variscite and manganese oxides.
The silicate assemblage consists of altered albite as a host for apatite, hureaulite, goethite, gordonite, leucophosphite, phosphosiderite, rockbridgeite, saleeite, tourmaline and variscite; altered beryl as host for faheyite, moraesite, roscherite and variscite, and muscovite hosting replacements and vug fillings of apatite, bermanite, childrenite, faheyite, frondelite, montebrasite, roscherite and variscite.
Bermanite occurs as reddish brown to terra cotta-red crystals and aggregates lining vugs in frondelite and spongy feldspar.
Associated species include bermanite, hureaulite, frondelite and strunzite.
