Evidence from the Superior Province of the Canadian Shield suggests the existence of several distinct lithostratigraphic associations in greenstone belts: (1) quartz arenite and carbonate-bearing sequences; (2) mafic-ultramafic volcanic sequences; (3) mafic to felsic volcanic cycles; and (4) ‘Timiskaming-type’ sequences of fluviatile sediments and calc-alkaline to alkaline by: Sedimentary facies in the Archean Timiskaming Group and their tectonic implications, Abititbi Greenstone Belt, Northeastern Ontario, Canada: Precambrian Research, Iler, R.K., Chemistry of silica – solubility, polymerization, colloid and surface properties and biochemistry.
Gross () has recognized that most Archean (> Ga) BIFs, such as those in the Abitibi Greenstone Belt of Canada, are closely associated with submarine volcanic rocks and are typically small.

Geology The Northway Project area is located along the Casa Berardi-Douay Deformation Belt within the northern Abitibi Greenstone Belt. The Archean Abitibi Sub-province is a subdivision of the Superior Province, and the oldest of the seven Canadian Shield Provinces.
Iron formations are stratigraphic units which are largely composed of iron-rich chemical sedimentary rock, here called ironstone. Most aspects of iron formations continue to be controversial and so one must read voluminous literature to appreciate either the range of iron-formation characteristics or the conflicting interpretations of those by: The Northern Miner is the world’s leading mining publication.

However, little is actually known about the overall 3D shape of the primate thorax, or how this is reflected in. Breaki er al. (, p) revealed an association of this metal with albitized, peraluminous granitoid dikes in the North Caribou Lake Greenstone Belt in the Sachigo Subprovince. Other studies have also indicated that holmquistite has a marked tendency to occur in.

Because of the dense station coverage and detailed 3 D velocity structure model in this region, this earthquake provides an excellent opportunity to examine how the 3 D velocity structure affects the finite fault inverse solutions.
