摘要
The Tongshi complex is the most actively metallogenetic for gold mineralization in western Shandong Province. Around it there are four tectonic strata units with different lithological characters, occurrences, geophysical and geochemical features. The Taishan Group characterized by high density, low skipping magnetic field and high gold content can play as gold source. The Paleozoic unit,high density, weak magnetic field and poor in gold, is ore-forming media. The Mesozoic-Cenozoic unit is of low density, low magnetic field as well as poor in gold, which is irrelative to gold mineralization. By analysis on tectonics, geochemistry and feasibility of every tectonic units around the complex, the conclusion can be drawn that the major gold mineralization took place in the hydrothermal stage at the end of diagenesis and assemble of elements include Au, Ag, V, Sb, Cr. According to gravimetric, magnetic and geochemical anomalies, three zones can been determined around the Tongshi complex.
