Abstract

This thesis is based in part on field work carried out by the writer during the seasons of 1937 and 1938; and during a brief trip in the winter of 1939. Thirteen of the producing mines were visited. Much useful information relating to the problems dealt with has been obtained from reports by various investigators on the general geology, mineral deposits, and certain intrusive bodies or the region. [...] This thesis is an attempt to assemble, grade, correlate, and plot on a map, all the available information pertaining to faulting in Western Quebec; and, from such a compilation, to draw certain conclusions as to the relations of faulting to the localization of economically important mineral deposits. A study was made to find the relationship between faulting and ore deposition in the Rouyn-Bell River region. The general geology and the distribution of faults are outlined. Faults are then classified as pre-ore and post-ore to suit best the nature of the problem. Following this descriptions are given of many of the major faults, and of the important orebodies of twenty-nine of the mining companies active in the area during the past or at present. The gold deposits are then grouped according to their relation to faults. An important part of the investigation was the compilation, from various sources, of a geological map of the Rouyn-Bell River region on a scale of one mile to the inch, showing the location of many of the mines and major faults.
