The Genetic And Prospecting Criteria Of Pyrite Gold

Pyrite is an important gold content, its genetic mineralogy research has played animportant role in gold genesis and prospecting. In this paper, by comparing thedifferent genetic types of gold deposit typomorphic characteristics of pyrite, thesimilarities and differences between them are drawn. Further, by comparing integratedTanlu fault on both sides of the crystal shape of pyrite in gold, trace elements, cellparameters, thermoelectricity, resistivity, the typomorphic characteristics ofdiscussion on both sides of the mineralization and prospecting marks.The morphology of pyrite is very complex, usually the cube and octahedralcrystal shape of pyrite is lacking in gold, the granularity of the fine, the crystal shapeis pentagonal dodecahedron and complex combination of gold, and the more kinds ofcrystals, the easier to form rich ore. The greater the crystal cell parameters shows thebetter mineralization. Composition of pyrite typomorphic is the most essentialcharacteristic of the mineral, the gold of pyrite increase along with the increase ofmain elements Fe/S, and the trace elements of Co, Ni ratio indicates the role of the oredeposit genesis. In addition, the high content of As is also an important symbol of richgold, and its always in linear positive correlation with Au.There is a close relationship between the pyroelectricity、 resistivity of pyriteand different origin、different size、different types of gold deposit ore, the thermalconductivity of P type of pyrite is often better than N type in gold content. From thecomparison of experimental data and charts, we found out that the higher the discretedegree of hot coefficient value of pyrite P type, the greater the size of the gold deposit,the greater the gold contents, but the experimental data show that the N type has lessrelation with the discrete degree. The mean change in discrete degree of P type pyriteis a quartz vein type gold deposit, and its less than the shattered altered rock type golddeposit. The skarn deposits is between the quartz vein type gold deposits and theshattered altered rock type gold deposit. N type, on the other hand, the mean changein discrete degree changing rule of N type pyrite is a quartz vein type gold deposit, itsgreater than the quartz vein type gold deposits, and the skarn deposits is between the quartz vein type gold deposits and the shattered altered rock type gold deposit. Fromthe resistivity, we found out that the resistivity value and the gold contents is not alinear relationship, while the average resistivity and the range of pyrite is in inverselyproportional with gold grade, thus the resistivity change of pyrite can qualitativeprediction of gold. The average change rule of the discrete degree of resistivity indifferent type of the pyrite mine is that the value of the skarn type gold deposit is farless than the quartz vein type gold deposit,and less than the shattered altered rocktype gold deposit.
