Abstract:

Lengjiaxi strata in Quxi gold deposit with high initial gold background value，gold that is easily to be released was activated，migrated，and then precipitated，enriched in local area，due to metamorphism and tectonism.In Early Yanshanian，due to compression of the intra-continental subduction and collision，tectonic thermal event resulting in melting of diver deep or melting in the Lengjiaxi Group strata to form granite magma.Magma underplating along the deep fault intrusion，in the process of intrusion the deep fluid mixed with metamorphic water and meteoric water，and extract the mineral formation of gold in Lengjiaxi group，the hydrothermal bring gold migrate to construct favorable parts of the uninstall enrichment and mineralization.Lengjiaxi stratum provide gold material sources for the mineralization of Quxi gold deposit.While Granite not only provide the source of the gold material，but also provide thermal power for the mineralization.

Key words: Lengjiaxi group, Granite, Mineralization, Material source, Quxi gold deposit, Hunan Province
