AbstractBasement topography and fault patterns across the southern plains of the Northwest Territories, as revealed by reflection seismic data, support the long-standing interpretation that a regionally extensive, orthogonal (northeast and a weaker northwest) pattern of structural lineaments influenced Middle Devonian facies development. Basement faults, typically of small throw and extent, fall generally into one of three groups as defined by strike direction: north-south, northeast-southwest, and northwest-southeast. A fourth set follows the crest of the Fort Simpson Magnetic Anomaly. There are both extensional and compressional linear features. The path of the Middle Devonian carbonate bank edge was affected by basement structures including: Celibeta High; north-south faults that are products of uplift; and regional lineaments, particularly the Liard Line and the boundaries of Cordova Embayment. Development of hydrothermal dolomite appears to have been enhanced on Celibeta High and along Tathlina Fault.
