Ore-forming information of quartz vein-type gold deposits——Taking Bainaimiao gold deposit

As an example, the ore-forming information of the Bainaimiao quartz vein-type gold deposits is dealt with. The second stage of gold mineralization (stage II) is an important ore-forming process; the intersected parts of main structure with other structures provide the favorable mineralization information; when the same form of pyrite crystals in one sample has two groups of thermoelectronic voltage, i. e. one group being positive and another group being negative and when the strong and relatively strong anomalies of Hg, F and/or As, Sb are overlapped by the weak anomalies of Au and Ag, the probable existence of blind orebodies at the depth could be predicted.
