The modal mineralogy for 32 Fe-Ti oxides and apatites supports the 2:1 oxide:apatite ratio for these samples from New York, Quebec, Norway and Sweden. Accessory minerals include: biotite, clinoamphibole, spinel, zircon and sulphides, oxygen fugacities range from 10-11 to 10-20, and T 600o to 1000oC. - K.A.R.
