Based on the characteristics of basic-ultrabasic rocks (belt) at the east part of the Shan- gxian-Danfeng fault and mineralization of iron, chromium and nickel ores inside, four zones of basicultrabasic rocks, named as A, B, C and D respectively, are delineated. Geological prediction of mineral resources inside those four zones has indicated that the basic-uhrabasic rock zones should have good potentiality for ore prospecting of magmatic iron, chromium and/or nickel deposit. Some recommendations to ore prospecting in this area are given in this paper.
