| Comments: | Bruce Jarnot did find and confirm tapiolite from the Hale Quarry. There were two specimens, one a complex crystal group (about 0.5 inches) and the other a similar size group that had altered 50% to pyrochlore. It resembled a hard yellow marble that, when split, showed the remains of tapiolite xls in the center. The IDs were made by EDX (element ratios) and X-ray unit crystal pattern. | |
