Abstract :

The studied area which contains the 1:100000 map of Nyshabour and some parts of 1:100000 map of� Soltanabad and Meshkan is located in north-east of IRAN and in the province of Razavi Khorasan.421 geochemical samples and 16 repetitive samples in order to control of error analysis.
These samples were sanded to Geological survey of IRAN for analysis after preparation 27 elements & 8 oxides were analyzed with ICP method that 17 elements were selected among them including: Ag, As, Au, Ba, Bi, Co, Cr, Cu, Mn, Ni, Pb, Sb, Sn, Sr, W, Zn.
Among of these elements, there of them (Ba, Sn, Sr) have censord data. After replacing of censored amounts, the natured break limit was separated in data and then multi-variable & mono-variable statistical tecnics were executed and different necessary articles were brought out from them. Then were drawn histograms, correlation- matrix, cluster Analysis and factor Analysis
(F1) First Factor = Cu, Co, Mn, Ni, N, Au
(F2) Second Factor = Sb, Bi, Ag, Sn, (Pb)
(F3) Third Factor = Pb, Zn
(F4) Forth Factor = Cr, Sr
(F5) Fifth Factor = Mo, As
After that was dram separtly of elements and factors
Also 131 heavy mineral samples were prepared and studie
