Ar. Choudhuri, RETRIEVAL OF THE TRACE OF THE TRUE AXIAL SURFACE ON AN OBLIQUE SECTION THROUGH A FOLD, Journal of the Geological Society of India, 45(3), 1995, pp. 311-316
On an oblique section, the line connecting the points of maximum curva
ture of the bounding surfaces of folded layers may not coincide with t
he trace of the actual axial surface. Methods have been suggested for
construction of the true axial trace on an oblique section.
