| 摘 要： | 本文以岩性—构造—事件法论述了夹皮沟金矿田地质演化历史,并建立了夹皮沟金矿田成矿模式,对金矿田成矿理论和金矿预测提出了新的见解。研究认为,该矿田金的物质来源具多源性,金矿形成具多期多阶段性。区内北西向弧形韧性剪切带是金的主要控矿构造。总结出该矿田具有“一型三式”的特点,即花岗—绿岩型,包括板庙子式、大线沟式和三道岔式。

| Abstract: | This paper describes the history of geological evolution with a method on lithology-structure-geological events, and a metallogeoic model for the Jiapigou gold deposit is established, providing the new suggestions for metal-logenic theory and prediction of gold deposits. The gold mineralization corresponds to the geological event; material sources for gold ore are of poly-genesis; and formation of gold is of poly-stages. Geological structures are the important factors for ore-forming process. The NW-trending ductile shear zone from Dalazi through Laoniugou to Erdaogou is a main ore-controlled structure. According to the comprehensive analysis on stable isotopes and ore-forming geological conditions, three ore-forming stages for gold field are proposed. Among them, early Proterozoic (1900-1600Ma) is main stage, and mid-late Proterozoic (1000Ma) and Mesozoic (240-140Ma) belong to the superimposed ore-forming stages. Based upon the metallogenic conditions on the country rocks, magmatite and tectonic, we come to the conclusion that the gold field is characterized by the granite-greenstone type (including Banmiaozi type, Daxiangou type and Sandaocha type). |
