Abstract

A simple workflow is presented for the graphical generation of structure contours for plunging cylindrical folds. Conventional plunge projection techniques are used together with extant section construction methods to complete fold profiles. Additional steps that, in effect, reverse parts of the plunge projection techniques transfer information from a fold profile plane on to horizontal planes of known elevations to generate structure contours. Sets of structure contours can be obtained for folded contacts and their axial surfaces. These structure contours can be used in conjunction with topographic contours to constrain the outcrop traces folded contacts and axial surfaces in areas of irregular topography. As part of the procedure, crest, trough and hinge points identified in a fold profile plane can be projected on to a geological map in their correct positions and elevations as part of the procedure. The workflow was designed for the frequently encountered case of a partially mapped trace of a folded contact surrounded by a collection of orientation data.
