马超营断裂带地质及地球化学特征

根据对马超营断裂带系统进行的地质—地球化学剖面研究，探讨了该带断裂构造活动及其元素地球化学迁移富集规律与构造地球化学分异之间的关系；分析了蚀变、矿化与成矿的关系，认为早期面型蚀变伴有成矿元素的活化和迁移，但无矿化富集，后期带状蚀变伴有金的富集成矿且以硅化、绢云母化为主要标志。从而，为马超营断裂带这一重要的以金为主成矿带的进一步工作、研究，提供了地球化学方面的依据。

CHARACTERISTICS OF GEOLOGY AND GEOCHEMISTRY OF MACHAOYING FAULTED ZONE

Based on the research on geology-geochemistry profile of Machaoying faulted zone, the faulted structural activity of the zone and the relation between migration-enriched law of element geochemistry and structural geochemistry differentiation are discussed. The correlations among alteration, mineralization and mineralization are analysed, and considered that the early planar alteration usually associated with activation and migration of mineralizing elements, but no mineralization enrichment, the later zonal alteration often associated with enrichment and mineralization of the gold, the major sign is silification and sericitization.Therefore, this paper provides the geochemical basis for further research of Machaoying faulted zone which major mineralization zone was gold enriched.
