ABSTRACT

This paper portrays an application of adapted manual process on selected geophysioal measurements to appraise the ilmenite deposits at Abu-Ghalaga district. It includes a systematic study of well-log investigations, interpretation and expressions of results.

The main petrophysical parameters, needed to evaluate an ilmenite body, can be derived from the combination of electrical and nuclear well-log data. A quantitative analysis of the different well-log records is usually satisfactory through "quick – look & cross-plots". The computer program will be best suitable, since the quantitative procedure may be very protracted if done manually.

As a result of this research a location of separate ore stores was established and a delineation of their petrophysical characteristics has been accurately achieved. The changes in the detected electrical resistivity and radioactivity values were found to correspond to lithological variations and inhomogenities in the ilmenite body itself. Several lines of evidence, such as those obtained from these well-log data, core samples, surface geophysical measurements and geochemical analysis support each other and narrow the wide range of other possible solutions.
