摘　　要：胶东西北部玲珑金矿田的主干构造的断裂对于胶东金矿的形成和分布有着重要的控制作用。通过对玲珑金矿田NE、NNE、NEE三组断裂构造带内所发育的节理进行分析,利用观测点优选方位节理进行古应力解析,结合构造配套关系将玲珑金矿田成矿期构造应力演化分为三个阶段,玲珑金矿田构造断裂性质从早期的压扭性转变为中期的压性与张性的过渡阶段,晚期表现为张扭性,矿床形成于构造应力转换期。拟在前人工作的基础上,以研究区的控矿构造节理为切入点,结合主应力分析与反演的方法,揭示研究区的控矿构造应力场的形成与演变规律。The faults in the main structure of the Linglong gold deposit in the northwest of Jiaodong play an important controlling role in the formation and distribution of the Jiaodong gold deposit.By analyzing the joints developed within the NE,NNE,and NEE fault zones of the Linglong gold mine,and using observation points to select directional joints for paleostress analysis,the evolution of structural stress during the mineralization period of the Linglong gold mine is divided into three stages based on structural matching relationships.The structural fault properties of the Linglong gold mine transition from early compressive torsional to mid compressive and tensile transitional stages,and exhibit tensile torsional characteristics in the late stage.The deposit was formed during the transition period of structural stress.Based on the work of previous researchers,this study aims to explore the formation and evolution of the stress field in the ore controlling structures of the research area,using the method of principal stress analysis and inversion as the starting point.
