john william pearson hbsc thesis abstract

in the summer of 1980, during reconnaissance mapping with the geological survey of canada a succession of mafic flows and volcaniclastic sediments, subsequently named the ingrid group, was discovered about 2500 metres west of the nain-churchill province's boundary.

the group consists of basalt, porphyritic basalt, conglomerates, greywackes and siltstone metamorphosed from upper greenschist to epidote-amphibolite facies.  these units observed have been deposited upon churchill province gneisses in aphebian to paleohelikian time and have been folded, faulted in a very complex manner.
