Geology and structure of the northern portion of the Cambrai Sheet

Abstract

The geology of the area investigated consists of a highly folded sequence of metamorphosed sedimentary rocks. Rock types encountered were interbedded slates, sandy and calcareous schists, sandstones, limestones, marbles and mica schists. The only representatives of igneous activity are hydrothermal quartz blows and altered dolerite dykes. Remnants of Tertiary sediments are found on the higher portions of the upfaulted Kanmantoo Series (older rocks of this area). Special consideration was given to the structure of the area, but interpretation was rendered difficult by the lack of outcrop and marker horizons.
