朝阳县贾杖子金矿产于中生代火山岩区，出露地层全部为白垩系义县组，主要由中基性－酸性－碱性火山熔岩、火山碎屑岩和次火山岩组成。金矿化常发生在火山活动晚期形成的各类碱性次火山岩与其它火山碎屑岩的接触带及其附近的破碎带中，受次火山岩与构造破碎带联合控制。文章在总结金矿化地质特征和成矿控制因素的基础上，主要从深部找矿和综合找矿方面进一步论述了该区的找矿前景。
朝暘縣賈杖子金礦產于中生代火山巖區，齣露地層全部為白堊繫義縣組，主要由中基性－痠性－堿性火山鎔巖、火山碎屑巖和次火山巖組成。金礦化常髮生在火山活動晚期形成的各類堿性次火山巖與其它火山碎屑巖的接觸帶及其附近的破碎帶中，受次火山巖與構造破碎帶聯閤控製。文章在總結金礦化地質特徵和成礦控製因素的基礎上，主要從深部找礦和綜閤找礦方麵進一步論述瞭該區的找礦前景。

Chaoyang Jiazhangzi gold deposit formed in the Mesozoic volcanic ,outcropping strata all be‐longed to Cretaceous Yixian Group , it is composed of mafic -acid -alkaline , pyroclastic rocks , and sub‐volcanic rock . Gold mineralization occured in the contact zone and nearby fractured zone w hich is formed by various alkaline subvolcanic and volcaniclastic rocks in the late volcanical activity . It is controlled by subvolcanic and structural fracture zones . This paper further discussedthe comprehensive prospecting po‐tential in the area mainly from deep prospecting on the basis of geological features of gold mineralization and ore-controlling factors .
