Origin of chromitite layers and pods in mantle and igneous cumulate sequences


        Massive chromatite occurs commonly in ophiolite sequences, and in this document internet access is given to unpublished ophiolitic chromite data from the Bay of Islands ophiolite of Western Newfoundland and the Thetford ophiolite of the Eastern Townships of Quebec.  The Bay of Islands data is derived from the Ph.D. thesis of Luca Riccio (Riccio, Luca, 1976. Stratigraphy and Petrology of the Peridotite-Gabbro component of the Western Newfoundland Ophiolites. Ph.D. Thesis, University of Western Ontario, 265 p.), whereas the Thetford data is taken from the Hounours B.Sc. thesis of Joanna Sharpe (Sharpe, Joanna L., 1983. Chromitite and Associated Ultramafic Rocks, Black Lake, Quebec. Thesis, Honours Bachelor of Science, University of Western Ontario, 73 p.).  I hope eventually to include a discussion of an important data set for the massive chromite units of the so-called 'Ring of Fire' cumulate bodies of Northern Ontario, that are currently being studied and described by Jordan Laarman, a PhD student at Western University.
        The 1977 paper by Church and Riccio  (Church, W.R. and Riccio, L. 1977. Fractionation trends in the Bay of Islands ophiolite of Newfoundland: polycyclic cumulate sequences in ophiolites and their classification. CJES 14, 1156-1165) classified ophiolites in terms of the crystallization sequences observed in ophiolites in general, as well as the specific nature of the trends in FeO/MgO ratio of both residual mantle and cumulate olivine, clinpyroxene and spinel, and TiO2 in clinopyroxenes.

       The figure "Partial Melting" versus "Fractionation" trends as evident in cumulate and residual mantle spinels illustrates the variation in xAl2O4 v xCr2O4 and FeO v MgO
        (corners of rhomb are MgAl2O4, FeAl2O4, MgCr2O4, FeCr2O4) can be accessed via the link:
     http://instruct.uwo.ca/earth-sci/fieldlog/Chromitite/Riccio/Riccio_Fig36meltvfract.jpg

      Partial fusion trends causes spinels to lose XAl2O4 and increase XCr2O4, and to increase Fe relative to Mg:
             MgAl2O4 + CaMgSi2O6 + Mg2Si2O6  = CaAl2SiO6 + 2 Mg2SiO4
                            K = (Pl x Ol2 ) / MgAl2O4 x Cpx  x Opx

    the Lewis Hills fractionation trends start at the same degree of partial melting as the Table Mountain, North Arm, Blow Me Down Mnt trend but shows an immediate increase in XAl2O4 towards spinels         with 55% MgAl2O4 and 0 XCr2O4, i.e. relatively Al enriched compositions. The Table Mountain, North Arm, Blow Me Down Mnt spinels trend initially towards FeCr2O4 but then turn towards                 FeAl2O4 enriched compositions.
