Geologic Characteristics And Metallogenicmodel Ofmatigou Gold Deposits

The Matigou gold deposit belongstothepangjiahe river-bifurcation gold metallogenic belt in south qinling early Paleozoic and Mesozoic gold copper and silver antimony-molybdenum metallogenic belt,golddeposit and hydrothermal activity,metamorphism and tectonic movement are related to the toughness and brittle shear zone.Since the Paleozoic era,the region has experienced the tectonic activity of different,different levels and different natures and provided the channel for the migration and enrichment of minerals.Since the beginning of jin ning period,the magmatic activity in the area has been intense,providing a heat source for the formation of the deposit.The extensive development of clastic rocks in the region provides the ore space for mineral enrichment and the geological conditions of metallogenic geology are favorable.The Matigou gold deposits is a medium-sized gold deposit found in south Qinling in recent years,Micro disseminated type,The ore deposit is located in jing antiformal north wing slightly bay,from arhat temple ~ tile kiln thrust fault(F9)on footwall to brittle ductile shear zone in the north west,Ore lithology mainly silty phyllite,metamorphic siltstone is given priority to,Both tectonic breccia.The brittle ductile shear zone from the shallow surface of the surface is gradually transformed from brittleness to brittleness,and the gold mineralization type is mainly structural alteration rock type.With the continuous development of geological exploration in recent years,The scale of gold deposits has been continuously expanded,But the research work has lagged behind,which severely impedes the continued expansion of the exploration results.Through the water chestnut ditch gold deposit geological characteristics,Ore mineral composition and so on carries on the system analysis and research,This article mainly understand water chestnut ditch main ore-controlling factors and metallogenic mechanism of the gold deposits,Clear and wall rock alteration deposit Ma Tigou relationship,and on this basis,the analysis of the ore forming process research,Explore the formation and enrichment regularity of ore deposits,Preliminarily establish the metallogenic model of ore body,The beneficial for future production.
