For evaluation of the mineral potential of Sirutr area
in the north east of Khorasan, 140 stream sediment samples were
analyzed for Ni , Co, Ag, Sb, Hg and Au. Results of these
analyses ind ica te an unusual assay for most of these elemen ts,
especia lly for gold a nd ant imony. Statis tical analyses and
co mparison of geologic map with the surrace anomaly maps
indicate a posit ive re lations hip between Ni a nd Co with mafic
and ultramafic rocks in the area; while the unusual distribution
of gold, antimony and to a lesser extent mercury can be related
to the hydrotbermal processes. From this study it is concluded
th a t the statistical analyses along with the geological and
geochemical studies are very useful in recognition of the
mineralized areas and understanding of tbe mineralizing
processes.
