%X 鲁西地区发育典型的绿岩带型金矿，在这里，我们以陆壳演化为视角，通过岩石学、地球化学结合金矿床实例讨论研究区绿岩带型金矿成矿期次及其矿源。结果表明，大约(2700~2600 Ma)为绿岩建造时期，可能富含金矿，金矿成矿物质主要来源于新太古代大规模的基性火山活动，TTG岩系的侵入加剧了Au元素的迁移富集，经过区域变质作用，发育的韧性剪切带提供了含矿流体的运移途径，在容矿构造部位形成金矿体。<br />
Typical greenstone belt type gold deposits are developed in western Shandong Province. From the perspective of continental crust evolution, the metallogenic stages and ore sources of greenstone belt type gold deposits in the study area are discussed by combining petrology and geochemistry with examples of gold deposits. The results show that the period of greenstone formation (2700~2600 MA) is probably rich in gold deposits. The ore-forming materials of gold deposits mainly come from the large-scale basic volcanic activities in the Neoarchean. The intrusion of TTG rock series intensified the migration and enrichment of Au elements. After regional metamorphism, the developed ductile shear zone provides the migration path of ore bearing fluid and forms gold bodies in the ore hosting structure.
