| 摘 要： | 新疆富蕴县萨尔布拉克金矿床位于准噶尔盆地北东缘之喀拉通克岛弧带,莫勒迪尔巴斯陶复向斜北东翼的北西端萨尔布拉克-阿克塔斯断裂带中;矿体受次级断裂萨尔布拉克韧性剪切带控制,具明显受地层岩性及构造控制特征;矿石类型属于蚀变岩型金矿,蚀变主要有毒砂化、黄铁矿化、硅化。通过综合分析,初步认为该区金矿属于早期变质热液形成矿胚,随后有多期地热事件发生,地下热水(液)发生多期蚀变叠加形成金矿床;总结了地层岩性、构造、褐铁矿"铁帽"、围岩蚀变和地球化学异常4个方面的找矿标志。

| Abstract: | Sarbulak gold deposit is situated in northwest Sarbulak-Akhtarskaya fault zone of northeast Moledierbasitaofu syncline,which lies in the Karatongk island arc belt on northeast part of Junggar Basin.The ore body is dominated by a secondary fault i.e.Sarbulak ductile shear zone,which is obviously controlled by formation lithology and tectonics.The ores of the deposit are altered rocks with major alterations as arsenopyritization,pyritization and silication.Comprehensive analysis has shown that in the early stage,the gold deposit was metamorphic hydrothermal protore,and after many phases of geothermal events,underground hydrotherm experienced multiple alteration superpositions to form the gold deposit.This paper has also summarized the prospecting marks from four aspects,including strata lithology and tectonics,limonite gozzan,surrounding rock alteration,and geochemical anomaly. |
