ABSTRACT: The target in this investigation is separation and delineation of
geochemical anomalies for the single element Cu in Mesgaran mining area,
eastern Iran. Mesgaran mining area is located in south part of Sarbishe county
with about 29 Km distance to the county center. This region is part of an
Ophiolite sequence and the copper anomalies seem to be related to a volcanic
massive sulfide (VMS) deposit whose main
part (massive sulfide Lens) has been eroded. In order to delineate Cu
anomalies, the boxplot as an Exploratory Data Analysis (EDA) method and concentration-volume
(C-V) Fractal modeling are employed. Both of the methods reveal low-deep
anomalies which are highly correlated with geological and geophysical studies.
As the main result of this study we show that Fractal modeling in spite of the
Boxplot, is not recommended for complex geological settings. The proved shallow
anomalies recorded by geophysical studies and defined by the used methods are
in accordance to the stringer zone of a volcanic massive sulfide (VMS) deposit
in Mesgaran mining area which means this region is the bottom of a VMS deposit
and geochemical anomalies are related to the remained parts of the deposit.
