The Geological Characteristics And Genetic Analysis Of Fujiapo Pyrite Mine In Fengshan County,Guangxi Province

The Fujiapo pyrite mine in Fengshan county is an important type of pyrite in Guangxi.Through various stages of mineral exploration,Based on the need for mineral resources exploration,The size of the reserves of the mine has been controlled.It is necessary to explore and evaluate the mineral resources mainly of pyrite that The stage of the division steps further to carry out the exploration of the pyrite mine in the area.At the same time,there is a different understanding and disagreement about the geological characteristics of mineral deposits in the mine in the past.The research of this paper is based on the study of the fieldwork and indoor research of the Fujiapo pyrite mine in Fengshan county,Guangxi Province the aim is to gain a better understanding of the geological characteristics of Fujiapo pyrite.Further identify,trap,or merge the pyrite ore body.In order to accurately grasp the characteristics of pyrite reserves,the scientific basis for future industrial exploitation is providedThesis research work for in-depth discussion of pyrite in the study area of ore-bearing bed,orebody characteristics,ore characteristics,alteration,mineralization stages and genesis of the gold deposits in the study.Made the following main understanding:1.Fujiapo pyrite mine is the main ore body in this mine,and coal seam is symbiotic mineral.The mining layer of pyrite is the first section?P³h₁?of the Permian Heshan Formation,which belongs to the coal-bearing sedimentary pyrite deposit.2.Pyrite ore structure of the ore are relatively simple,is layered,like layered.The ore body is larger and the pyrite reserves are abundant.3.The structure of the pyrite ore is granule structure,microcrystalline structure,microscopic scale muddy structure,aphanitic structure,self-shaped semi-self-shaped granular crystal structure,its granular crystal structure,Crystal structure.Ore with disseminated structure,plaque structure,local with directional structure.4.The alteration of the surrounding rock of the pyrite ore body is mainly silicification,pyrite mineralization and limonite mineralization,kaolinization,chlorite and sericitization.Coal slag exposed to the surface of the weathering of carbonaceous mudstone?shale?formed in the general sericite and chlorite.5.Analysis of influencing factors and metallogenic processes of mineralization based on sedimentary action and regional tectonic activity.The formation process of Fujiapo fluid ore is divided into two stages.The first stage is Dongwu Movement since the handling--decomposition--depositional metallogenic stage;The second stage is that the Indosinian movement and its influence lead to the formation of the Youjiang sag,is the tectonic sag stage.In addition,the exploration of the ore ore prospecting signs is further explored.
