Extract

(1) The interpretation of Dash et al. (1987) that the quartz–sillimanite–garnet (khondalite) assemblage of Orissa represents a metamorphosed deeply weathered soil profile(s) is based on a considerable body of new geochemical data: 59 new major and trace element rock analyses and 9 new major element rock analyses(ca. 1800 determinations) compared with the previous basis of 2 rock analyses for major elements only from Orissa supported by 3 for major elements only from other parts of India and 4 from Sri Lanka (ca 90 determinations—table 4).
