AbstractThe geological database is derived from previous regional mapping of the Ware (NTS 94F) 1:250 000 scale map area, compiled as part of the Geological Survey of Canada's Central Foreland NATMAP project. Geological features represented by attributed points, lines, and polygons have been compiled into a GIS dataset suitable for stand-alone use, or integration with other data sets. Provided geological features extend traditional geological map information with greater detail and enhancements such as measured section locations and fossil localities. The Ware map area extends across the fold and thrust belt of the northern Rocky Mountains. The geology of the area is characterised by predominantly sedimentary strata, of Middle or Late Proterozoic to Paleogene age, exposed in northeast-verging thrust sheets, folds, and normal fault-bounded grabens. Early Proterozoic orthogneiss and Paleogene granite and dacite dykes occur along the western edge of the map-area. Upper Triassic and unconformably overlying Cretaceous strata of the Foothills Belt occur in the northeastern most corner of the map-area where they are overthrust by a panel containing Proterozoic strata of the Muskwa Assemblage unconformably overlain by Cambrian through Middle Devonian miogeoclinal rocks. The Muskwa Assemblage is intruded by 779 Ma gabbro dykes. To the southwest, major anticlines and several thrust faults expose Proterozoic to Silurian strata. The Paleozoic carbonate platform succession undergoes a gradual facies change southwest into fine clastics and basinal carbonates. Loss of thick carbonate panels results in a change in structural style from thrust fault-dominated to fold-dominated. In the central part of the area, sets of closely spaced folds and thrust faults deform Cambrian through Triassic units with older units predominating to the southwest until metasedimentary rocks of the Neoproterozoic Misinchinka Group are encountered in the last thrust sheet beside the Rocky Mountain Trench graben. This graben contains the Cretaceous and Tertiary Sifton Formation, which also lies unconformably on Proterozoic to Ordovician strata to the southwest. In the southwest corner of the map-area are folded and faulted exposures of the Neoproterozoic Ingenika Group overlain unconformably by the Lower Cambrian Atan Group and Cambro-Ordovician Kechika Formation. Minor Late Triassic gabbro and Paleogene dacite dykes intrude the succession.
