"The Monarch, Kicking Horse, Shag, Munroe, and Oldman carbonate-hosted, sulphide deposits of the southeastern Canadian Cordillera share many of the characteristics of Mississippi Valley-type deposits, such as stratabound lenses, pods, and disseminated sulphide minerals locally accompanied by breccia-vein systems. The deposits are hosted in dolostone located at major facies transitions between shallow-water carbonate platformal and deeper basinal rocks along the ancient Paleozoic margin of the Canadian Cordillera. They are associated with fault and breccia structures located nearby or along the platform-basin facies transition. The location and geometry of these deposits reflect the interplay between structures (i.e. deep-seated faults located at platform-basin transition) and lithologies (i.e. permeable and reactive stratigraphic units). Sulphides, consisting of sphalerite, galena, and, to a lesser extent, pyrite, are present as fracture, breccia matrix, and vug-fillings, as well as replacement of dolostone host rock. Dolomite and calcite are the common gangue minerals. Quartz is present at three showings of the Shag deposit but is otherwise absent (except for trace amounts at Kicking Horse). Paragenesis is relatively simple and shares many features across the studied deposits. Generally, sulphide paragenesis starts with pyrite, followed by sphalerite andthen galena"--Abstract. gccst Geology gccst Petrology Paradis, Suzanne, 1958- author. Canada. Natural Resources Canada.
