| Abstract: | On the purpose of seeking the main metallogenic sources of the Carlin gold deposits in the Pingle depression,two typical deposits are analyzed according to the field work and isotope results of H and O.The isotope results of H and O in those two deposits indicate that the main composition of metallogenic fluid transits from magmatic hydrotherm to meteoric water from west to east,but the main metallogenic source comes from magmatic water.According to the regional tectonic analysis,the contrast of the occurrences among the formations,ore bodies and ore-controlling faults,the authors consider that the infiltration of fracture networks is caused by faults.The result also shows that the structure is the main ore-controlling factor.The combination of "fold and interlayer-gliding fault" model has a special effect to the mineralization.Gold ore bodies mainly exist in the interlayer-gliding faults. |
