11iddbis ((ANALCIME with PYRRHOTITE inclusions and PHILLIPSITE)), $10 MINIMUM BID, Boron Open Pit Mine, Kramer Borate Deposit, Boron, Kern County, California, 2 x 1.5 x 1.2 cm, Thumbnail | |
Looking at mindat.org I found out that many of the species, especially zeolites, are found in vesicles within the basalt at Boron. These are best collected as thumbnails. Jim Minette purchased the Carnahan collection which contained thumbnails of these species and combinations of species from Boron. This one has large Analcime crystals with small included Pyrrhotite. Phillipsite are probably the smaller crystals in the vesicle. ex Jim Minette collection, ex Carnahan. |
