34 and 35. Calculation of strike-slip displacement Where any vertical phenomenon is present, for example the axial plane of a symmetrical fold, vertical strata, igneous dyke, etc. the lateral displacement by the fault can be measured directly from the map. e. it is not an oblique-slip fault, see Fig. 25) then we can simply find the lateral shift by measuring the displacement of any chosen structure contour on a given geological boundary. Where strata are folded it is easy to measure the lateral displacement of fold axes or axial planes (Fig.

Map 15 The western partofthe map comprises a three· point problem enabling us to draw structure contours at 10m intervals on the base of the ironstone. Assuming the top of the ironstone to be 20 m higher, why does borehole B penetrate only 15m of ironstone? East ofthe fault (a normal fault of high angle of dip), produce the structure contours and re·number them 20 m lower (since the fault is shown as having a down throw of 20 m to the east). Shade outcrops of iron ore on both sides of the fault.

E. Phillips's The Use of Stereographical Projection in Structural Geology 3rd edition (London, Edward Arnold, 1971), which deals fully with these terms. It is best to restrict the term 'pitch' to such linear features as striae, slickensides or lineations on a plane. They have both plunge (the angle they make with the horizontal) and pitch (the angle they make with the strike direction of the plane). Reject the use of the term pitch when referring to folds . Since problems entailing pitch can be solved (quite simply) by the use of stereographic projection they are not included in this book.
