M.Sc. Thesis Proposal

Marco Tortola




The proposed study will provide a detailed examination of diagenetic processes, especially dolomitization, in terms of dolomite types, distribution and geochemistry of Silurian and Devonian carbonates of the eastern side of the Michigan Basin (Huron Domain). The proposed research will address questions concerning  the nature and composition of dolomitizing fluids which modified the pre-existing limestones, the timing of dolomitization, the extension of diagenetic events, the possible geochemical model for diagenetic fluids that can explain the occurrence of dolomite and other diagenetic minerals, the paragenetic sequence of different types of dolomite, and the evolution of diagenetic fluids in terms of variation of trace elements and stable isotopes in different types of dolomite.

The study will be performed on rock core samples collected for the Nuclear Waste Management Organization (NWMO), in the area of the Bruce Nuclear Site located near Tiverton, Ontario.

Previous investigations of carbonate sequences from Ordovician to Devonian in the Michigan Basin demonstrated the precipitation of dolomite cements, pore-filling saddle dolomite and other minor diagenetic minerals such as calcite, fluorite, anhydrite and pyrite by a late phase of hydrothermal fluids characterized by high temperature and high salinity. However, there is a little attention been paid for carbonates present in the Huron Domain in terms of diagenesis and dolomitization. Hence, the proposed study and using integrative petrographic, geochemical carbon and oxygen stable isotopes, Sr-isotopes and fluid inclusion analyses will shed more lights on the origin of dolomitizing fluids and their relationship to tectonic setting in this part of the Michigan Basin.
