The determination of fluoride in silicate rocks by ion-selective electrode; an update

Whole-rock analyses of core samples from the 1988 drilling of Kilauea Iki lava lake, Hawaii

“…In addition to the above, the analyses include determinations for Cl, F, and Cr. Cl was analyzed using the selective ion electrode (SIE) method outlined in Jackson and others (1987), while F was analyzed using the SIE method of Kirschenbaum (1988). The Cr analyses in jobs CJ12 and CJ13 were obtained by inductively coupled plasma-atomic emission spectrometry (ICP-AES) following the method described in Lichte and others (1987), while Cr in job WC69 was obtained by XRF.…”

Geochemical data of drill core samples of carbonatites and associated igneous rocks, Magnet Cove Complex, Arkansas

“…Ferric iron, reported as Fe 2 0 3 , was calculated from the total iron as obtained by WDXRF and the measured ferrous iron content. F" and CI" were determined by ion-selective electrode potentiometry using either the method of Kirschenbaum (1988) or of Bodkin (1977) for F and that of Aruscavage and Campbell (1983) for CI (analysts: C.J. Skeen and N.H. Elsheimer).…”

Geochemical data of drill core samples of carbonatites and associated igneous rocks, Benton, Arkansas

“…F" and CI" were determined by selective ion electrode by C.J. Skeen and J.R. Gillison-Colbert using the methods of Kirschenbaum (1988) and Aruscavage and Campbell (1983), respectively. Total S was analyzed by first combusting the sample in a sulfur analyzer and then measuring the evolved sulfur dioxide by an infrared (IR) detector (Kirschenbaum, 1983; analyst: C.J.…”
