| 摘 要： | 根据路线地质调查、实测地质剖面及200余处典型玛瑙矿点、矿化点的调研信息,将义县组划分为5个喷发旋回,阐述了阜新地区义县组及相关潜火山岩中分泌体状玛瑙和断裂充填型玛瑙的主要特征;并得出如下结论:上述两种成因类型的玛瑙层控性明显,主要产于义县组喷发旋回Ⅰ、Ⅱ中;断裂充填型玛瑙脉体走向多呈北北西至北北东向;有利赋矿岩石依次是安山玢岩及相关隐爆火山碎屑岩、玄武岩、火山碎屑岩。在调查研究基础上,指出断裂充填型玛瑙是今后玛瑙找矿的主要目标,重点勘查靶区主要位于紫都台—七家子、老河土—十家子地区。

| Abstract: | According to the route geological survey along actual geological sections as well as the study of more than 200 agate mineral spots and mineralized spots,the Yixian Formation is divided into five eruption cycles.This paper describes the main features of the agates belonging to body-like secretory type and fracture filling type in Yixian Formation and related cryptovolcanic rocks in Fuxin area.Some conclusions have been reached: The stratabound characteristics of the agates of these two genetic types are obv... |
