AbstractThe Mount Martin map area is situated at the southern end of the Franklin Mountains in a foothills physiographic setting. The geology of the area is characterized by sedimentary strata of Carboniferous to Paleogene age, exposed in a series of box folds whose geometry is controlled largely by the competence of the Carboniferous Mattson Formation. Permian strata formerly included in the upper member of the Mattson Formation have been mapped separately as the Tika formation. Upper Paleozoic and Triassic strata are overlain unconformably by Lower Cretaceous rocks of the Chinkeh Formation and younger units. Sub-Cretaceous erosion is a major control on the distribution of upper Paleozoic and Triassic units within the map area. Paleogene conglomerate and sandstone, interpreted as representing a syn- to post-orogenic fluvial system, is locally preserved in the La Biche River valley. The sinuous appearance in map view of major structures is largely due to en echelon linkages of smaller culminations involving interfering northeast- and northwest-trending folds. The east limb of the Mount Martin anticline is cut by a reverse or thrust fault of minor displacement (tens to hundreds of metres). The Kotaneelee gas field produces from Middle Devonian carbonate units in a structural culmination associated with the Mount Martin Anticline.
