In this study, 115 samples taken from the stream sediments were analyzed for concentrations of As, Co, Cr, Cu, Ni, Pb, W, Zn, Au, Ba, Fe, Mn, Sr, Ti, U, V and Zr. In order to outline mineralization-derived stream sediments, various mapping techniques including fuzzy factor score, geochemical halos and fractal model were used. Based on these models, concentrations of Co, Cr, Ni, Zn, Ba, Fe, Mn, ...

Anomaly recognition has always been a prominent subject in preliminary geochemical explorations. Among the regional geochemical data processing, there are a range of statistical and data mining techniques as well as different mapping methods, which serve as presentations of the outputs. The outlier’s values are of interest in the investigations where data are gathered under controlled condition...

Detection of deep and hidden mineralization using the surface geochemical data is a challenging subject in the mineral exploration. In this work, a novel scenario based on the spectrum–area fractal analysis (SAFA) and the principal component analysis (PCA) has been applied to distinguish and delineate the blind and deep Mo anomaly in the Dalli Cu–Au porphyry mineralization area. The Dalli miner...

roudgaz prospect area is a cu, sn, pb, zn, and au polymetal vein system located to the southeast of gonabad and in the northeast of lut block. oxidan subvolcanic tertiary rocks with monzonite to monzodiorite porphyry composition intruded the metamorphic rocks of middle jurassic. the majority of intrusive bodies are affected by carbonation, argillic, sericitic, and silicification-tourmaline alte...

The most significant aspect of a geochemical exploration program is to define and separate the anomalous values from the background. In the past decades, geochemical anomalies have been identified by means of various methods. Most of the conventional statistical methods aiming at defining the geochemical concentration thresholds for separating anomalies from the background have limited the effi...

the gold mineralization in kurdistan province of iran was classified as shear zone gold type by some of the researchers. in the current study, the geochemical samples collected from the secondary environment, stream sediments, at the sw of saqquez area were used to investigate the geochemical characteristics of the gold mineralized zones in this environment. the multi-variant statistical analys...

introduction mohammad-abad oryan is the only potential source of borate in the north-east of iran located in 50 km south of sabzevar. the area is located in tuff marl, tuffaceous marl, volcanic braccia and tuff braccia structures. remote sensing techniques, geological studies and integration of this data in gis were applied in an area of about 600 square kilometers to locate the promising areas...

The purpose of this study is to determine geochemical anomalies on lithogeochemical data from Ardestan area, Central Iran, using concentration-number (C-N) fractal modeling and staged factor analysis. Staged factor analysis is used to the recognition of genetic correlation and elimination of non-indicator elements in three steps. Factor scores of elements were calculated and geochemical data cl...
