摘　　要：通过对老柞山金矿床地质特征和成矿机制的研究和分析 ,得出老柞山金矿床形成的成矿模式。Au、Cu等成矿物质来自元古界麻山群 ,且Au具有幔源性 ;后期作用使金受到反复多次活化和迁移 ,得到初步的富集 ;燕山期脉岩体的侵入使金再次得到活化转移 ,以至成矿 ,并且岩浆活动为成矿提供了充足的热源和部分矿物质。同时对老柞山金矿的成矿标志进行了厘定。The minerlization model of Laozuoshan deposit can be got by studying and analyzing the geological character and mineralization mechanism. The mineralization materials such as Au and Cu etc. came from Mashan group, Proterozoic, and the Au sourced from the mantle. Gold suffered from activation and transference many times during deuteric action and primarily enriched. The gold got activation and transference again and the deposit formed owing to the intrusion of rock mass in the Yanshanian stage, and the magmatic activity provided plentiful heat and partial mineral substances for deposition. Meanwhile, the ore-hunting indicator of Laozuoshan deposit is collated and stipulated in this paper.
