Philipsburgite, Quartz Locality: Black Pine Mine (Combination Mine; Black Pine Tailings; Black Pine Dump), Flint Creek Valley, John Long Mts, Philipsburg District (Flint Creek District), Granite County, Montana, USA (Locality at mindat.org) Size: 2.3 x 1.8 x 1.6 cm. Bright, translucent, emerald-green botryoids richly coat the quartz matrix of this unique and exceptionally fine thumbnail specimen of the rare phosphate philipsburgite from the Type Locality - the Black Pine Mine, Philipsburg Area, Montana. The bulk of the philipsburgite actualy lies on the base of a very sharp, iron oxide-coated quartz crystal. Very uncommon in this quality. Ex. John White Collection. This is certainly the style found from the type pocket, as well, I am told. Mineral

Phillipsite-K (FOV 3.5 x 2.3 mm) Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry; Carrière Mont Saint-Hilaire), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada Found July 1997. Optical ID by WH (on another specimen). MOB coll. The phillipsite from the Poudrette pegmatite contact zone is probably “-K” since that is the only variety listed by Horvath (Lapis, Rivista 2000) for this environment. (See child "photo" for optics.) These phillipsite balls are superficially similar to gobbinsite balls from the same environment. But the individual phillipsite xls clearly have squarish cross-sections. This type of phillipsite was associated with faujasite-Na and may be an indicator for the latter. (As far as I know, faujasite was found only once at MSH.) The diaphanous white rosettes are probably gmelinite-Na (but chabazite can look similar in this environment). Mineral

Phillipsite-Na Locality: Palagonia, Northern Iblean plateau, Catania Province, Sicily, Italy (Locality at mindat.org) Size: small cabinet, 5.6 x 3.4 x 1.8 cm Phillipsite (rare zeolite) This is a fairly rare member of the zeolite family that at times can have calcium, or potassium, or sodium as its chief constituent. Phillipsite has cemented brecciated rock and formed a series of botryoidal groups, the largest of which measures 1.0 cm across. These spheres are snow white, and lustrous. I am told it is quite good for the locality! Mineral

Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry; Carrière Mont Saint-Hilaire), Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada FOV 1.1 x 1.3 mm. Via Monteregian Min. MOB coll. The brown color seems typical for phosinate from Kola (at least as posted on Mindat). In this case the brown is "enhanced" by the ubiquitous MSH cavity coating. Phosinate is a very rare mineral - even at MSH. But it's from Horvath so the ID should be good. Mineral

Phosphophyllite Locality: Unificada Mine, Cerro de Potosí (Cerro Rico), Potosí City, Potosí Department, Bolivia (Locality at mindat.org) Size: miniature, 4.0 x 2.5 x 1.1 cm Phosphophyllite This small miniature features a razor-sharp, 3-cm-long phosphophyllite twin perched on sparing matrix, displayed to maximal impact. Phosphophyllite of this quality is a collector's Holy Grail, so seldom found and, when found, seldom affordable. A piece like this probably came out in the "old era" of the 1950s-1960s, and although modern attempts to find more have proven successful, they have not been of this limpid quality and lustre. In person, the color is unique - there is nothing else quite this hue of green-blue in the mineral kingdom. Ex. Robert Whitmore Collection. Mineral
