Baldface Mountain Volcanic Field

The Baldface Mountain Volcanic Field is located in the Chilcotin Highland of western British Columbia, belonging to the central segment of the E-W oriented Anahim Volcanic Belt. The field covers an area of ~400 km2, consisting of a scattered collection of shield volcanoes, cinder cones, and lava flows in varying degrees of erosional state and exposure. These occurrences are mostly found as mountains and topographic highs within the landscape, such as the eponymous mountain located in the north of the field. Lavas found at these volcanic centres consist of an alkaline, bimodal suite of rocks, ranging from basanites and trachybasalts to trachytes and phonolites. Mafic rocks appear to dominate, and some samples of these rocks are nepheline-normative. Geochemical data, including major and trace elements, and sampling localities can be found in Kuehn (2014).
