Abstract
Shabogamo gabbro, an olivine gabbro, intrudes the metamorphosed sedimentary rocks in the Wabush Lake map area, southern part of the Labrador geosyncline. In close spatial relation to this intrusive is an amphibolite schist that appears conformable with these meta-sediments. Field evidence is by itself insufficient to demonstrate whether this amphibolite schist is a metamorphosed sediment or whether it is genetically related to this olivine gabbro. Since large amphibolite schist bands occur in the Smallwood Mine, determination of the origin and relation of the amphibolite schist to the olivine gabbro is of special importance because this will determine ore potential at depth in this mine.
