Colemanite on Ulexite
U.S. Borax open pit (Boron pit), Boron, Kramer District, Kern Co., California, USA
Cabinet, 10.3 x 3.2 x 3.0 cm
Ex. Al Ordway
A stalactitic crystal of fibrous, pearlescent, and translucent, snow-white ulexite, measuring 9 cm in length, is festooned with lustrous and translucent, white crystals of colemanite, to 1 cm in length. Unusual! I have not seen this association before. It comes with a label indicating it was collected by Jim Minette, here, in 1980.
