Abstract
Head-on (half-Schlurnberger) resistivity measurements along ten profiles (Cheng, together with sixty-seven Schlumberger soundings, have been carried out at Olkaria in 1981 and 1982. Analysis of this data has been by twodimensional modelling with initial models derived from dimensional interpretation of the soundings (Kenya Power Co. Ltd, 1984). It has been found that "cross-overs" in the head-on data, usually interpreted qualitatively as the location of fault zones, are better modelled by simple lateral resistivity changes in the, vicinity. Strong nearsurface variations in resistivity, indicated by rapid fluctuations in the head-on data for small means that the precise location and dip of conductive zones cannot be well-determined.
