Variscite Variscite A specimen of variscite veined with crandellite, wardite and other species from the Fairfield, Utah locality. This deposit was owned for many years by Arthur Montgomery and mined for the decorative variscite nodules. Its a breccia in the Phosphoria formation in Utah. Apparently phosphate leached out of the surrounding rock by water circulating through the breccia, was redeposited as a complex aluminum phosphate of which variscite was the starting material and the others are alteration products.
Specimens are fairly common in museum collections but none has been produced for many years.
Although this is only a slab, it was originally a large nodule. Its a very colorful, very good example of this locality.
