Structure contour maps and exercises – The Shear Zone

Various exercises that can be used to develop skills in the construction (and interpretation) of structure contours (aka strike lines) - for planar surfaces, folded surfaces and irregular unconformity surfaces. Most of these feature in various videos on the Shear Zone channel. All artwork by Rob Butler. Classic coal seam problem maps - introducing…
