Separating geochemical anomalies of lithium by the use of Concentration-Number fractal modeling on sedimentary rocks of the Jam and Sorkheh 1:100000 sheet, Semnan Province

The current study was conducted on sedimentary units of the 1:100000 sheet of Jam and Sorkheh in Semnan Province, northeast of Iran. Because of its special geochemical properties, lithium can be concentrated in sedimentary rocks with clay minerals. Samples were collected from stream sediments and lithogeochemical in three steps and were processed using Concentration-Number fractal modeling. Concentration-Number fractal modeling is a suitable geochemical exploration method to separate anomaly from the background. It was utilized to identify anomalous areas for lithum and the results were presented in the form of maps. As a result, The Gharavol kooh area of Biabanak in central part of sheet of Sorkheh. According to the lithology of the area, which contains marl and clay minerals (Illite and Cholorit), It was main anomaly between the two sheets. This area should be further investigated in Detailed exploration studies.
