PRACTICAL 1: TOPOGRAPHIC CONTOURS, STRUCTURAL CONTOURS AND GEOLOGICAL MAPS.
At completion of this practical you will be able 1/ to determine the strike, dip and dip direction of geological surface from their form lines (i.e. their traces on a geological map), 2/ to construct the intersection between a geological planar surface and the surface topography, 3/ to determine the thickness of a geological formation from map analysis.
