| 摘 要： | 文中系统论述了柳坝沟金矿床的多金属元素原生晕地球化学特征,运用多元统计方法,结合地球化学各参数信息,勾勒出矿区原生晕异常形态,建立了元素轴向分带序列,探讨金矿床剥蚀程度并建立了原生晕叠加模型。认为柳坝沟金矿床西段头尾晕共存,Sb、Bi反分带,显示出多阶段叠加成矿的特点,是下部有盲矿体存在的反映;东段基本属正向分带序列,地球化学参数较强的波动,可能预示着深部有盲矿体存在。313号脉西段矿体遭受一定剥蚀,矿段中段和东段遭受轻微剥蚀。综合分析推断西段深部矿化远景较好,中段较好异常分布在海拔高度1400 m以上的较浅部位,东段深部前景最佳;为矿区深部找矿提供了重要依据。 |

| Abstract: | The geochemical features of primary halo of Liubagou gold deposit are systematically discussed in the paper, using multivariate statistical methods combined with geochemical parameters information;the anomalous features of primary halo are outlined and the axial zoning sequence of elements are established;the extent of denudation is analyzed and the primary halo superimposed model is built. In the western part of Liubagou gold deposit, the front elements are coexistent with the rear elements, and the anti-zoning of Sb and Bi shows the characteristics of superposition of multi-stage mineralization, reflecting the existence of blind ore bodies. In the eastern part, the axial zoning sequence is basically normal;the strong fluctuations of geochemical parameters indicate that the blind ore bodies may exist there. While in terms of denudation, the western part ore bodies of the No.313 vein has undergone relatively strong erosion, the middle and eastern part have undergone minor denudation. According to the results mentioned above, we predicted that a good mineralization perspective exists in the western part;that for the middle part, the anomalous area is at the elevation of above 1400 m;and that the eastern part is of the best prospect. This study provides important evidence for deep prospecting in the mining district. |
