Detailed mapping of the north-west quadrant of the 1: 100 000 scale Isukasia geological map sheet was begun in 1981 (fig. 16). The area was previously visited during the 1977 helicopter reconnaissance mapping programme (Allaart et al., 1978) and from this work the stratigraphy was known only in the broadest of terms. The 1981 work has shown that the area is comprised of five principallithostratigraphic units, listed in Table 3.
