11iddbis ((ANALCIME on SAPONITE)), $10 MINIMUM BID, Boron Open Pit Mine, Kramer Borate Deposit, Boron, Kern County, California, 2.5 x 2 x 1 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 a vesicle lined with dark Saponite covered with colorless Analcime crystals. ex Jim Minette collection, ex Carnahan. |
