The mantle derived magmatogenetic gold deposit in western Shandong area could be defined to the gold deposit related to Mesozoic intrusions. Intrusive rocks relating to gold mineralization are mainly intermediate and alkaline rock stocks and dikes occurring along faults or adjacent areas or overlapping areas of different faults. At least some ore forming material was derived from lower crust or upper mantle, or partly from country rocks, in terms of C, H, O, S and Pb isotopic compositions. The mineralization age of each gold deposit in the Luxi area has big difference: The K Ar isotopic age of goldbearing quartz vein is 962Ma; the age of basic rock sills of Jinxing gold deposit in Yiyuan is 141Ma. The both represent the mineralization age of stratiform multimetal deposit. The inferential mineralization age of Jinchang gold deposit in Yinan is about 128~121Ma, based on the Rb Sr isotopic ages of biotite (133±6Ma from early stage skarn and 128±2Ma from late stage skarn). The area with low denudation degree and concealed rock mass and its surrounding is the favorable area for gold prospecting. The main prospecting direction of stratiform fine grained disseminated gold deposit is in the periphery of intrusive bodies, and the prospecting direction of other types of gold is in intrusive bodies or their contact zones. Due to no systematical deep studies on Mesozoic intrusions in this area, there have no precision dating method on the mineralization age. At present, no feasible method of mineralization age of Guilaizhuang gold deposit in Pingyi is available.
