Using Dip Vectors to Analyze Structural Data

Abstract

Few geologists are aware of the utility of dip vectors in the analysis of planar structural data. Like a pole plot, a dip vector represents the attitude of a plane in space as a single point on a stereonet. However, the dip vector is a more direct portrayal of the dip direction and dip amount; visualization of the plane's orientation thus is facilitated for most observers. Use of dip vectors is widely applicable in structural geology and engineering geology. Our experience in training a broad array of students from undergraduate geology majors to seasoned geologists and engineers indicates that inclusion of dip vectors with more traditional plots of poles and great circles significantly enhances understanding of planar structural data.
