“…The Boothia Uplift acted as a local buttress against the deformation front : interaction with the south-directed orogenic stress reactivated faults associated with the Boothia Uplift (Turner & Dewing 2004;Dewing et al 2007a;Jober et al 2007), and fluid movement through these faults was responsible for formation of Zn deposits in the Cornwallis District, including the Polaris Zn-Pb deposit (Dewing et al 2007a). The Devonian clastic wedge is preserved on Banks (Thorsteinsson & Tozer 1962;Miall 1976), Melville (Harrison 1994) and Bathurst (Anglin & Harrison 1999) islands, but is absent on Victoria Island (Thorsteinsson & Tozer 1962). The proximity of these islands to Victoria Island allows for the assumption that this area was also part of the same fluvio-deltaic environment (Embry 1991a).…”

Despite the presence of known economic resources in Canada's Arctic archipelago, Victoria Island remains understudied. This study addresses the fluid history and economic potential of two major carbonate units on Victoria Island by integrating fluid inclusion microthermometry with SEM‐EDS analysis of evaporate mounds. Three cements containing fluid inclusion assemblages (FIA) occur in the Neoproterozoic Wynniatt Formation: saddle dolomite, brown dolomite and calcite, in paragenetic order. The two dolomite‐hosted cements have average homogenisation temperatures (Th) for FIAs (n = 3) of 108°C (saddle) and 101 and 116°C, but metastability precluded determining salinities; most calcite‐hosted fluid inclusions are too small and/or necked to obtain Th values, but rare larger inclusions have salinities from 1.7 to 0.4 wt. % NaCl equiv. SEM‐EDS analysis of evaporate mounds indicates the fluid changed from an early K‐rich (saddle dolomite), to a later K + Na (brown dolomite), and finally Na‐rich (calcite), which suggests mixing of two end‐member fluids (i.e. Na‐rich and K‐rich). Dolostone of the lower Paleozoic ‘Victoria Island formation’ contains two cements: early quartz and late dolomite. Quartz‐hosted FIAs (n = 2) have an average Th value of 126°C, and salinity of 23.2 wt. % NaCl equiv., whereas FIAs (n = 3) in dolomite have average Th values of 109, 116 and 124°C; metastability precluded determining salinity. Evaporate mound analysis for the cements indicates evolution from a Na‐rich to a Na + K fluid through interaction with reservoir rocks. A reduced, metal‐rich fluid was present during quartz precipitation, as implied by the presence of pyrite framboids along growth zones and nanoparticles of barite and sulphide minerals (Zn, Cu and Pb) in evacuated inclusions, which suggests the area may have potential to host base‐metal mineralisation. Importantly, distinguishing different fluid compositions in both of the case studies would not have been possible without evaporate mound analysis and therefore the results emphasise integrating this technique into diagenetic studies.
