Determination of geochemical anomalies of stream sediments in Pb-Zn Songol mine of north Khomein by using Singularity index mapping

The Chenar area of Khomein is located in the Sanandaj-Sirjan tectonic zone and in the Malayer-Isfahan metallogenic belt.This region has the mineralization of Pb, Zn, Ba, Ag and secondary mineralization such as quartz, hematite, limonite, calcite and malachite. In a geochemical study of drainage sediments, we were taken 127 samples and were analyzed 14 elements such as As Ba, Ca, Ce, K, Mn, Pb, S, Sr Th, U, W, Zn, and Zr and anomaly was determined by Lopiliteh and the singularity index method., The majority of elements are in the background according to anomalous maps by Lopiliteh method and the anomalies are seen only in limited areas of the region. The hidden anomalies are better identified in the maps of singularity index method and there is a good relationship between the derived anomalies and the position of the Sangol Pb-Zn mine in the region. The enrichment of elements such as As, Ba, Ca, Ce, K, Mn, Pb, S, Sr, Th, U, W, Zn, and Zr is shown by the singularity index method in the region. In this study, two districts with anomaly were identified as the future exploratory target.
