gh,
KSZ, Kapuslasing Structural Zone, mostly thought of as highly metamorphosed Archean green schist and amphibole facies. Discusses many times in reviews and especially the 43-101 reports. The Abititi subprovince is located south and east of the KSZ. For a detailed description look under section 7.1.3 of the last 43-101, I have difficulty following this so will not attempt to simplify it here.
