In gold deposits of Penglai County, dikes are associated with gold mineralization temporally and spatially.Petrology and geochendtry of dike rocks indcate that they have different resources and evolution, and canbe divided into three series, i. e. acidic dike rocks which come from partial melting of old metamorphicrocks, intermedia- basic dike rocks and granodiorites which are derived from mantle source contaminatedby continenal crust, and the basic dike rocks be derived from the enriched mantle. The gold mineralizationis related to these magma activities.
