| 中文摘要:为了更加科学有效地部署甘肃省金矿勘查找矿工作，必须对全省金资 源总量作出定量预测，对省内各成矿带的金资源潜力作出定量评价。文章对甘肃省已发现的 429处金矿床（点）的资料及全省1∶20万区域化探资料进行了统计和研究，建立了甘肃省金 资源总量丰度估算模型、品位_储量回归预测模型及全省各成矿带金资源潜力分布模型。通 过定量预测得知，甘肃省金资源总量的上限值为3?166 t，金资源总量为2?420.6 t；西秦 岭成矿带的金资源潜力最大，占全省金资源潜力的37％，祁连成矿带次之，占24％，扬子 成矿带占15％，北山成矿带占13％。据甘肃省岩金资源回归预测模型，岩金矿床在甘肃省具 有极大的资源潜力。 |

| Abstract:In order to arrange the gold mine exploration work of Gansu Province scientifica lly and effectively, we must make a quantitative prediction of the gold resource reserves and resource potential in each metallogenic belt of Gansu Province. Ba sed on statistics and studies of the data from 429 gold deposits, ore occurrence s and mineralized spots and the 1∶200?000 regional geochemical data from Gansu Province, the authors established the total gold resource reserve estimation mo del and the grade_reserve regressive prediction model. The resource potential ap praisal of the overall gold resources and of each metallogenic belt in Gansu Pro vince was also conducted. The quantitative prediction reveals that the upper val ue of Gansu gold resource stock is 3?166 t, the gold resource stock is 2?420.6 t, and the proven reserve is 709.6 t. The gold resource potential of the wester n Q inling metallogenic belt is most promising, making up 37% of the gold resource p otential in Gansu Province. The Qilian metallogenic belt possesses the second pl ace and accounts for 24%. The Yangzi metallogenic belt accounts for 15% and the Beishan metallogenic belt accounts for 13%. |
