Abstract
The occurrences of mineral ore deposits and disseminated sulfides in wadi Dendekan are geologically thought to be associated with parts of the shearing fault and the alteration shear zone, which is composed of porphyritic rhyolites – dacite and metamorphosed volcanics highly fractured rocks occupying the all parts of the studied area. Mineralogical analyses that were done on bedrock samples of the oxidized and alteration zones indicated that there are several anomalous spots of minerals reached up to 3.6, 62.9, 87 and 202 ppm associated with Au, Ag, Pb and Zn respectively. Therefore, the magnetic, self-potential SP, resistivity and induced polarization surveys were applied critically interpreted at south Wadi Dendekan area to delineate the mineral ore deposits in terms of depths and extensions. The interpretation of magnetic data was carried out by using the 3D Euler deconvolution, analytical signal and source parameter image techniques. The results indicated that the depths of such highly magnetized ore deposits are ranging from near surface up to 50m deep. However, the results of the SP survey showed distinctive negative and positive anomalies ranging from − 40 to 10 mV. Most of these anomalies occupy the shear, silicified zones, alterations zones and rock contacts. The Gradient resistivity map showed low resistivity values, not reach 90 Ohm.m, with variable width. The induced polarization (IP)-chargeability data were measured in the time domain. The positive anomalies on the IP-chargeability map are clearly coinciding with the sites of alterations, shears and contact zones. Six 2D resistivity/IP imaging profiles that were measured along the sites of anomalies selected from the magnetic, resistivity, chargeability and SP maps in the study area and were inverted using the RES2DINV program. The results of 2D-resistivity and IP inversions indicated that there are anomalous zones of high conductivity and chargeability; indicating probable locations of ore deposits and/or disseminated minerals. On the base of the integrated results, at least two suggested locations are recommended for drilling to confirm such results and mineral potential of the study area.
