Popis: The identification and separation of soil geochemical anomalies using the concentration-number (C-N) and concentration-area (C-A) methods was conducted at the Zarshuran Carlin-type Au deposit, NW Iran. Log-log elemental plots fitted with straight lines show C-N and C-A relationships of Au, As, Sb and Cu. The thresholds obtained from the two methods are similar. Element concentrations can be divided into three segments that correlate with a particular rock type including mafic rocks, serpentine schist (within the Iman Khan Anticline), Ghaldagh limestone and Zarshuran shale units. Various structural features and corresponding alteration show that geologic structures play an important role in the discrimination of geochemical anomalies and element distribution in soils.
