摘　　要：为查明山东归来庄金矿的成因信息和成矿过程,笔者通过系统梳理成矿地质背景和矿床地质特征,并运用黄铁矿Rb-Sr、碳氧稳定同位素和流体包裹体等方法,查明归来庄金矿是中低温成矿流体经过多期次、多阶段演化,形成于中侏罗世晚期的矿床。在此基础上结合前人研究成果,建立了成矿模型。To understand the genesis information and ore-forming process,the pyrite Rb-Sr,stable C-O isotope and fluid inclusion analyses are used in combination with the systematic study of metallogenic geological background and geological characteristics of gold deposit in Guilaizhuang gold mine,Shandong Province.The results show that Guilaizhuang gold deposit is formed by multiple-stage evolution of medium-low temperature hydrothermal fluid in the late Middle Jurassic.The metallogenic model is then established based on this study and previous research results.
