Sorry, no etymologies found.
Regional mapping undertaken by BRGM in 1986 identified a NE-SW trending package of Archaean to Proterozoic age quartzitic metasediment, gneiss and amphibolite, as well as numerous itabirite units containing millimetre to centimetre thick bands of magnetite.
The reported 10 metre intercept is composed of 4 metres of abundant quartz, followed by 3 metres of metasediment followed by a further 3 metres of abundant quartz from the interval of
Field observations suggest that the metasediment footwall (predominantly quartzites) are the basal unit of the Central Slave Cover Sequence and are unconformable on top of basement gneiss.
