| Comments: | Cooper & Stanley (1990) p. 100: "An old trial on the Low Pike vein above Potts Gill [320358] yielded small amounts of minutely crystalline philipsburgite containing considerable phosphate substituting for arsenate. The IR spectra of some samples (M.P. Cooper Collection) suggested that the substitution proportion might be sufficient to render the mineral kipushite [Braithwaite & Ryback, 1988]. However, specimens analysed by XRD (BM(NH)) are closer to philipsburgite and a well-crystallized sample, from the D. Hacker Collection, analysed semi-quantitatively by EPMA shows a somewhat higher arsenate: phosphate ratio than type philipsburgite. (det. Leicester Univ.)." Cooper & Stanley (1990) p. 115: "Although the high phosphate content of one specimen analysed by IR led Braithwaite & Ryback (1988) to suggest that it may, in fact, be a highly arsenatian kipushite this species has not so far been identified by XRD from Low Pike. Moreover, a semi-quantitative analysis of a well-crystallized sample shows an As/AS+P ratio slightly higher than type philipsburgite (det. J. Faithfull, Leicester Univ.: EPMA." | |
