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.
In the altered zone surrounding frondelite it occurs associated with phosphosiderite, jahnsite and leucophosphite. In some cases cyrilovite coats variscite crystals or occurs in association with saleeite blades in spongy feldspar.
Small sprays of limonite-stained needles associated with tavorite have been found in cavities in albite; and minute, lustrous, doubly terminated crystals have been found in association with crystals of cyrilovite, phosphosiderite and leucophosphite in vugs in large, fibrous-botryoidal frondelite masses.
Associated (later) minerals include variscite, fluellite, leucophosphite, unknown #1, hewettite, tyuyamunite, torbernite and tiemannite/ corderoite, commonly all on the same specimen.
The minerals occur as somewhat globular coatings on fragments of brecciated jasperoid rock in direct association with crystallized fluellite, leucophosphite, strengite-variscite and anatase.
Associated crystallized species may include wavellite, hewettite, tyuyamunite, torbernite, leucophosphite, anatase, tinticite, phosphofibrite, blue unknown #1 and strengitevariscite.
Leucophosphite [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]
A very interesting occurrence at Gold Quarry is that of crystallized leucophosphite from location 1.
