| 摘 要： | 老洞坡银矿床位于围山城成矿带东延部,出露地层由下古生界大栗树组(Pz1d)和上古生界歪头山组(Pt3w)组成。老洞坡银矿体的发现显示歪头山组地层上、中、下三部均为含矿层,银矿体受朱庄背斜,歪头山组下部第五岩性段和构造控制。查明该矿床的原、次生地球化学异常特征,将老洞坡银矿床与破山、银洞坡银矿床的地质地球化学特征进行对比研究,在指导找矿上具实际意义。

| Abstract: | The Laodongpo Ag deposit in the Weishancheng ore belt is confined to the Upper Paleozoic Waitoushan Formation（Pt3w）. The orebodies are controlled by the Zhuzhuang anticline and lithologic character. Preliminary and secondary geochemical anomalies for the deposit may be correlated with those for the Poshan and Yindongpo deposits. |
