tss VARISCITE, CRANDALLITE, WARDITE?, MILLSITE?, Clay Canyon, Fairfield, Tooele County, Utah, 10 x 7 x .6 cm | |
Clay Canyon is the type locality of several rare phosphates. This is an excellent example of multiple phosphate minerals in a Fairfield nodule. The dark green is easily identified as Variscite and the yellow brown is Crandallite. The other rarer minerals are harder to identify, Wardite, Millsite, etc. I believe the the blue grey concentric mineral is Millsite. |
