Application of Geochemical and Statistical Methods for Prospecting of Ore Deposits in North· East of Khorasan.

Abstract

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.
