| Abstract: | The new metallogenetic mechanism of Xiaoqinling gold deposits is briefly described .The gold and gold alloy hydride migrate to shallow regions of the crust.The hydrogen is oxidized forming water.In high temperature hydrothermal solutions,the gold migrate as liquid nanometer gold particles and liquid nanometer gold alloy particles.With a decrease of temperature,the ore deposits formed by precipitation,condensation and enrichment of gold which is in the state of solid nanometer gold and solid nanometer gold alloy in low temperature hydrothermal solutions. |
