The accompanying drawing shows ground contours at ten-metre vertical intervals on a map.
(a) On the drawing supplied, draw a vertical section (profile) on the line EF.
(b) Vertical boreholes at A B and C strike a stratum of ore at altitudes of 40m, 30m and 65m, respectively. Determine the dip and strike of the stratum.
(c) Draw the outline of the outcrop.
