Abstract:The gold-bearing albite-carbonate breccia in the Shuangwang gold deposit is one of typical gold-bearing hydrothermal breccia bodies in the Qinling breccia belt, which is controlled by Fengzhen-Shanyang contemporaneous fault. This paper studied the zircon SHRIMP chronology and petrochemistry, founded that range from sericite slate to albitized slate and albitized breccia, Na2O gradually enriched and K2O gradually depleted, which is a negative correlation,indicating Na brought in and K took out in the ateration process.The formation of albite-carbonate breccia was not a single process but experienced hot-water Sedimentary, single component of hot water with the Syngenetic metasomatism, hydraulic fracturing, hot fluid crypto-explosion, hot fluid boiling, superimposed hydrothermal mineralization, supergenic metallogenesis and other diagenetic mineralization superposition. The range of ages from zircon SHRIMP dating of breccia is large, 423 Ma~513 Ma and 808 Ma~1166 Ma are are two peaks, similar to zircon ages of Devonian sedimentary strata in South Qinling; the youngest zircon ages are 280.1Ma~277.5Ma, representing the lower limit of crypto-explosive breccia.The ore-bearing breccia has experienced three stages: (1) the late devonian, hot water sedimentary in Feng-tai pull-apart basin; (2) during Early-Carboniferous (342Ma), feng-tai basin occured tectonic inversion,and hot alkaline hydrothermal fluid derived from deep earth upwelling,which formed metasomatic alteration and hydraulic breccia;(3) the early-Permian,alkaline carbonate fluid occurred cryptoexplosion and the formed cryptoexplosive breccia. According to the studies, the hydrothermal breccia tectonic system were characteristics of multi-phase and multi-stage superimposed diagenetic.
