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.
