Saline Ca-Na/Cl type groundwaters and brines sampled in deep mines over an extensive area of the Canadian Precambrian Shield have elevated Br Cl ratios which may indicate that the chlorinity of these waters was derived from the infiltration of residual evaporitic brines, remnants of the great marine incursions of the Paleozoic era.

Boron concentrations in these waters are generally low Cited by: Geochemical and isotopic evidence for a genetic link between Canadian Shield brines, dolomitization in the Western Canada Sedimentary Basin.

Hypersaline brines are common in deep mines across the Canadian Precambrian Shield, as well as in several other deep continental terrains, but their origin has remained enigmatic. These solutions may reach total salinities as high as g/l and Cited by: Geochemical and isotopic evidence for a genetic link between Canadian Shield brines, dolomitization in the Western Canada Sedimentary Basin, and Devonian calcium-chloridic seawater Article Full.

Hypersaline calcium/chloride shield brines are ubiquitous in Canada and areas of northern Europe. The major questions relating to these fluids are the origin of the solutes and the concentration mechanism that led to their extreme salinity. Many chemical and isotopic tracers are used to solve these by: Saline groundwaters and brines in the Canadian shield: Geochemical and isotopic evidence for a residual evaporite brine component.

New petrologic, geochemical and isotopic data are reported from a suite of mafic dike and lava flow samples collected from sites within the western Canadian Cordillera. Samples range in age from Eocene to Quaternary, and document a significant transition in mantle chemistry that occurred sometime after 10 Ma.

Saline Ca-Na/Cl type groundwaters and brines sampled in deep mines over an extensive area of the Canadian Precambrian Shield have elevated Br/Cl ratios which may indicate that the chlorinity of these waters was derived from the infiltration of residual evaporitic brines, remnants of the great marine incursion of the Paleozoic era.

Hypersaline Ca/Cl brines of marine origin deep within the crystalline rocks of the Canadian Shield are typically highly depleted in potassium and boron compared to their concentrated seawater parent brine.

While this depletion in both solutes is not accompanied by a major alteration in their original marine B/K ratios, their initial marine δ 11 B has been lowered.

A 3–5 km deep borehole into granite is expected to encounter high salinity brines exceedingmg/L total dissolved solids (TDS) such as those found in granites underlying the Canadian Shield, Fennoscandia, and elsewhere [1,2,3].High salinities aid in the safe disposal of deep boreholes because (1) they indicate isolation from fresh recharge, and (2) their greater Cited by: 1.
