Integration of structural, gravity, and magnetic data using the weights of evidence method as a tool for kimberlite exploration in the Buffalo Head Hills, Northern Central Alberta

The weights of evidence model derived from the integration of structural lineament maps, the Buffalo High (BH) and Buffalo Utikuma (BU) terrane boundary, Bouguer gravity, and magnetic characteristics of the BH and BU terranes in the Buffalo Head Hills area revealed maximum favourability for kimberlite exploration along the BH and BU terrane boundary. Within this corridor, higher favourability are in correspondence of NNEtrending lineaments and their intersections with NE and ENE lineaments. This relationship favour an hypothesis of kimberlite emplacement through a major zone of weakness in the basement, characterized by the BH and BU terranes boundary.
