| The ore deposit geological feature research based,based on in field sampling and indoor work,Rong of the deposit brass structure,light characteristic,chemistry type were studied by means of sample finishing,analysis and microscopic identification,electron probe,discuss the genesis of the deposit.The mining area sampling is the drilling sample,basically covers all the lithology and the structure of the mining area,and the depth is both,cut 49 pieces of representative light piece.Through with the microscope observation,found metal minerals up to 23,10 kinds of non-metallic minerals,mineral associated particularly complex,chalcopyrite and 19,pyrite and 18 species,bornite and 14 kinds of metal mineral intergrowth,visible multi mineral accountable to each other and in the same light visible metallic minerals formed in different conditions of associated.First clarify the contact relation of the chalcopyrite occurrence state and chalcopyrite and other metallic minerals,chalcopyrite associated characteristics study of chalcopyrite type structure,optical properties and chemical composition of three aspects.Exsolution structure focuses on chalcopyrite structure types,there are ten types of solid solution,by comparing the solid solution of the occurrence and the elevation,that honor the mining area has at least ten times more stable ore-forming condition;the classification of Chalcopyrite by optical characteristics,can be divided into 4 categories,and the elevation of chalcopyrite different optical features of contrast and occurrence of the associated characteristics,characteristics of middle low temperature shallow depths on both sides of the high,low temperature and the temperature drop of the chalcopyrite mineralization environment,the same light brass for mineral in different lithology,can see 2~3 different light rays in the same chalcopyrite by electron microprobe data;geochemical triangle for chemical classification of chalcopyrite,chalcopyrite can be divided into 8 categories,all kinds of relationship between chemical composition and mineral form,brass optical features,can be found in the same chemical Chalcopyrite formed in a variety of different types of rock.The same rock have more minutes different chemical types of chalcopyrite and chalcopyrite light are the same,but by a variety of different chemical composition of the hydrothermal formation,the same chemical composition of chalcopyrite can have different optical characteristics.The above evidences show that the mining area is the result of the multi stage and the hydrothermal solution of different components. |
