The contents of a computerized lexicon database are displayed in the form of a range chart that demonstrates the spatial and temporal relationships of lithostratigraphic units to tectonostratigraphic terranes of New Brunswick. The chart provides a reference basis from which to derive the accretionary history of these terranes.The tectonostratigraphic zonation of New Brunswick is based upon the uniqueness of the pre-Taconian stratigraphy within each fault-bounded terrane.From northwest to southeast, the following terranes and cover sequences are recognized:Matapedia
Corrected bottom‐hole temperatures from 35 wells, together with measured and assumed rock thermal conductivities, are used to estimate linear geothermal gradients and effective thermal conductivities in the Jeanne d’Arc Basin in offshore eastern Canada. Heat‐flow density values calculated for each well location indicate that heat‐flow density is slightly higher in the deeper northern part of the basin than in the southern part. It appears that the heat‐flow density distribution is affected by fluid motion within the sediments and not by heat generation or basement topography. Dehydration is suggested as the mechanism that produces the fluid flow pattern that influences the heat‐flow density distribution in the basin, and a simple fluid flow model of the Jeanne d’Arc Basin is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
