Abstract


This paper studies the bridge saddle gold mineralization to start controlling factors , the use of structural analysis method , through the study of fluid inclusions and the use of geochemical , geophysical and other technical means , the ore deposits were integrated metallogenic prediction , made the following main results and new insights : 1. through analysis of gold deposits in the saddle bridge deformation characteristics and evolution of shear bands is proposed study area through four major ductile shear zone deformation . In the first phase of thrusting from north to south , to determine this shear zone ( mineralized zone ) the location and shape of occurrence ; second period is from south to north thrusting , controlling the position of band deposits ; the third slip - slip lead sheets, transformation and positioning on the orebody . Greater impact on the mineralization which was two , thirty-two . As for the band 's fourth groups of widespread brittle fault is post-mineral structure of the mineralization is not much significance to the destruction of the ore body displacement distance is also smaller. (2) By analyzing the spatial distribution of deposits and rock contact relationships that orebodies are mainly distributed in Tong Yu Temple group on rock section , the lower part of the host rocks are mainly quartz biotite- sericite phyllite and calcium quality quartz sericite phyllite . 3 through the mineral deposits containing gold - pyrite Standard Type Characteristics and its relationship with gold mineralization , the area can be divided into four pyrite , where the second and third phases of pyrite the main minerals containing gold . 4 Through the study area ore quartz inclusions study mineralization homogenization temperatures of 210 ℃ ~ 260 ℃, salinity of 7.8 ‰ ~ 4.5 ‰, mineralization depth of about 1km ~ 2km, low temperature epithermal deposits in the genus . 5 geochemical analysis shows that the bottom line in CM33 about 30 to 50 m depth range , from 17 points along the geochemical orientation south, ore bodies occur ; 25 lines at about 1200 meters above sea level within the range of things , there may be the presence of a gold mine . 6 According to the geological conditions and geophysical data analysis, 25 lines to the east of the orebody still showed the left column to the right line style , they are hosted in biotite- quartz mylonite dark gray over light gray white, gray-green sericite ultramylonite or sheet rock Mi among them is the upper bound of carbonaceous phyllite and lower bounds for the biotite quartz mylonite ; y3 survey line 4 to the 10th spot abnormalities , 25 -line section of the abnormal No. Ⅱ may be caused by a small orebody .
