摘　　要：通过综合分析旧店金矿区新近发现断裂的地质特征和成矿元素地球化学特征,认为旧店金矿区存在韧性断裂。该韧性断裂形成于主成矿期之前、黄铁矿—石英成矿期之后,故发生了成矿元素的初步富集。由于该韧性断裂和1号脉的不协调性及其地质特征,限制了韧性断裂在成矿方面所起的作用,但对胶东地区蚀变岩型金矿床和石英脉型金矿床相互间的关系的研究带来新的启发。Based on the comprehensive analysis on the geological characteristics of the new fault structure and the geochemical characteristics of its ore-formationg elements, a new ductile-shear zone was discovery in Jiudian region. The ductile fault was formed in the times between pyrite-quartz mineralization period and main mineralization period. As the geological characteristics of the new fault structure was consisted with that of the No. 1 zone, the ductile-shear zone played trivial role in mineralization, but it will bring new inspiration for the research of the correlation between the gold deposit of the type of quartz vein and that of fault altered rock in Jiudian region.
