A feeder dike of olivine gabbro is exposed " below " the now tilted sequence.
Gabbro may also contain small amounts of olivine ( " olivine gabbro " if substantial amount of olivine is present ), amphibole and biotite.
"' Baltimore Gabbro Complex "'is a hypersthene gabbro with subordinate amounts of olivine gabbro, norite, anorthositic gabbro, and pyroxenite.
The Muskox intrusion can be separated into three sections, including an olivine gabbro feeder dike to the intrusion, another contact margin zone, and an upper layered series.
Weathering of the Muskox dipping sequence has exposed a cross-section through the entire dipping sequence, starting with the Coppermine flood basalts in the north above the roof of the magma chamber, down through the igneous layering of the Muskox intrusion and into the keel region of the intrusion and its intersection with the olivine gabbro feeder dike that forms the southernmost sector.
The well-layered lower units of ultramafic rocks comprising the Great Dyke are locally overlain by erosional remnants of Stratigraphically each sub-chamber is divided into a lower Ultramafic Sequence of dunites, harzburgites, olivine bronzitites and pyroxenites together with narrow layers of chromitite that constitute the bases of cyclic units and that are extensively mined along the Great Dyke, and an upper Mafic Sequence mainly consisting of a variety of plagioclase-rich rocks, such as norites, gabbronorites and olivine gabbros.
