Book Description

Cores drilled from a quarry north of Montreal show a distinct lithostratigraphic unit occurring below the Upper Cambrian Cairnside Formation. The unit was previously considered as the Covey Hill Formation of the Lower Potsdam Group. This paper describes the regional geological setting, lithology, and depositional environment of this unit. Evidence for considering the unit as part of the Rivière Aux Outardes Member (Clark, 1966) is presented. Correlations with other stratigraphic units in southern Quebec are discussed along with evidence for a possible Cambrian carbonate platform in the region. Two scenarios of possible regional depositional episodes are also hypothesized.

Book Description

This paper documents some aspects of the lithostratigraphic and sedimentological attributes of the Upper Cambrian Cairnside Formation, as observed in drill core and in surface exposures in a quarry near Covey Hill, southern Quebec. The paper begins with a review of previous research and stratigraphic terminology, then describes the lithology and depositional environment of the uppermost beds of the underlying Covey Hill Formation. The two units of the Cairnside Formation are then described and correlations with other localities are discussed. The final section briefly describes the Cairnside Formation depositional environment.

Book Description

Presents & discusses findings of a study to determine whether differences in petrophysical characteristics previously observed between rocks from the Giant and Con mines were associated with the presence of soluble mineral phases in the rocks. The study involved monitoring the resistivity of water used to immerse samples from the two mines (basalt and sericite schist), over a period of 340 hours, after vacuum saturation. The results show the differences between the resistivity-time curves of the water in which the samples were immersed. Suggestions for further studies are presented in the conclusion.
