fi Johnson Subject EXAMINATIOONF VERMONT 66 TALC BY RAY DIFFRACTION AND DIFFERENTIAL THERMAL ANALYSIS PROJECT NO 0503.01 e New Brunswick N.J. March 29 1977 Schelz Dr. J. P. Schelz | to - Mr. G. Lee The following composite samples of Vermont 66 talc have been analyzed by 1 continuous scanning ray diffraction for qualitative mineralogical composition 2 slow scanning ray diffraction for the presence of amphibole minerals CTFA Method J4-1 and 3 differential thermal analysis for the presence of quartz CTFA Method J5-1 and serpentine minerals 1/17 - 1/21/77 1/24 - 1/29/77 ' 1/31 - 2/4/77 2/7 - 2/11/77 2/14 - 2/18/77 2/21 - 2/25/77 2/28- 3/5/77 3/7 - 3/12/77 The samples appear to be typical of Vermont 66 talc samples previously examined chlorite levels approxi- mating those of 1976 composite talc samples No quartz serpentine or amphibole minerals were detected in these samples fallagher Regina fallagher Regina Gallagher gm .
