Quantifying and correcting errors derived from apparent dip in the construction of dip-domain cross-sections

This paper deals with the errors introduced in the construction of cross-sections due to the use of apparent dips and thicknesses when projecting data onto the plane of section. These errors are analyzed under the perspective of cross-sections constructed with the dip-domain method. A method to evaluate variations of unit thicknesses due to distortion during projection is presented, and modifications to the dip-domain method are proposed to account for them, including the use of apparent bisectors. Methodology is discussed for inclined section planes, and the equations to calculate apparent thickness on inclined sections are presented. An analytical definition of cylindrical folding is also derived. (C) 2002 Elsevier Science Ltd. All rights reserved.
