Results of optical, thermomagnetic and electron microprobe analyses of titanomagnetite grains
Abstract
This paper presents results of a study of titanomagnetite from specimens of ten different rock units. The rock units comprise trachytes, basalts, ignimbrites, nephelinites, olivine melanephelinites and welded tuffs from Kenya, with ages ranging from recent to Precambrian. The correlations of the stability index with opaque petrology and with thermomagnetic analyses of the titanomagnetite and titanomaghemite bearing specimens appear to be significant. Electron microprobe analyses of the titanomagnetite grains indicate a high percentage of “impurities” in the low stability index specimens and elevation of the Curie point in the high stability index specimens.
