   Systematic Geochemical Exploration in the 1:100000 sheet of Maksan
  
   Abstract
   The study area is located in the Sistan and Baluchestan Province, in the Jazmurian Quadrangle, between 60 to 60 30' E and 27 30' to 28 N. this sheet is located in the Jebal-e Barez Mountains, southeast Iran, that is an active metallogenic zone. Lithology of the area includes shale, sandstone, conglomerate, limestone, dolomite, marl, clay limestone, granite, granodiorite, tuff breccia, agglomerate, and alluvium.
   The structures in the area include faults and folds that are bounded by N-S, NW-SE, and E-W active major faults.
   Geotectonically, the area belongs to the Lut- Bazman zone in which the last tectonic activity started by the Late Cretaceous Bazman intrusive.
   Various factors affect the design of sampling network. So the drainages were mapped using topography maps and aerial photographs. By application of GIS, other factors such as petrology, tectonics, contacts and alteration zones were also considered. The designed network contained 755 sampling points. But only 640 points were sampled because of accessibility and security.
   The samples were analyzed for Zn, Cr, Ti, Mn, Sr, Ba, Au, As, Sb, Bi, Hg, W, Pb, Ni, Mo, Sn, B, Be, Ag, Co, Se and Cu elements. Au analyzed by atomic absorption and the other elements by ICP-MS methods.
   After processing and analyzing the obtained data, 16 anomalies were identified. The geochemical anomalies were controlled by heavy mineral and mineralized sampling. Based on the heavy mineral data and filed checking, finally three zones were introduced for further exploration.
   The first anomaly is located in the Maksan 1:50000 sheets, at north of Espast. The second anomaly is located around the Sunit Mountain, Kashkin alley and Renduki. The third anomaly is located in the south of Surak, in the Asaki valley.
