XRD - Tremolite in Talc
Copiea: ESA, GSB, GG, H~C, OLK, J. Felqer,~
C\uaific:atiOn:
Objective:
Results: Six samples of talc products from Bay Street were run by XRO for tremolite. All of them except Lot 412 show a small content of tremolite. Attention is called to Sample Lot 886 of this group of samples. It is described as T076 product, milled 8/25/76. Another sample, Lot 886, also described in identical fashion but roilled 8/27/76 was analyzed on a previous day and refOrted in a different report. Project 76-0296-CIM-BS. Both contain tremo1ite at 0.15\ level.
