中文摘要:长城式金矿主要受长城系岩石层间角砾岩破碎带、褐铁矿化和有机质(碳)含量控制,与岩石层位和性质无关。成矿热液可能是在伸展构造体系的控制下,超糜棱岩化变质作用衍生的变质流体或者深熔岩浆作用衍生的岩浆热液流体,在构造动力驱动下上升至盖层破碎带与天水混合的产物。它们在白云岩破碎带中渗流形成碳质含矿热液;在碎屑岩破碎带中形成硅质含矿热液。
Abstract:Based on a preliminary study of such characteristics of the Changcheng type gold deposits as its distribution, its source beds, the nature of ore-bearing fluid and the relationship between mineralization and limonitization and organic carbon, the authors have reached the conclusion that the Changcheng type gold deposits are mainly controlled by the intraformational breccia shatter zone of Changcheng System, limonitization and effect of organic carbon, being independent of the horizon and the properties of rocks. The ore-forming hydrothermal fluid was produced by the mixing of metamorphic fluid derived from ultramylonitization or magmatic hydrothermal fluid derived from anatectic magmatism with the meteoric water under the control of the extensional structural system.
