| 中文摘要: |
| 红庄-元岭金矿床位于豫西熊耳山金及多金属成矿带南亚带上，是近年来发现的中型金矿床。通过对该矿床地质特征、成晕元素共生组合及分带特征的研究，认为该区原生晕分带序列整体为正常序列，49号勘探线中存在前缘晕元素与近矿晕元素叠加共存的现象。地球化学参数反映了该区成矿具多期多阶段的特点，部分参数在深部有向高值转折的趋势，Au及近矿晕元素异常规模向深部具有增大趋势，表明深部有一定找矿潜力。结合原生晕轴向序列特征及地球化学参数、异常规模随深度的变化特征，认为浅部找矿的重点应放在海拔约400m以上，攻深找盲的重点应放在海拔300m以下。 |

| The Hongzhuang-Yuanling gold deposit, which was discovered in recent years, is located in the southern sub-belt of the Xiong’ershan Au polymetallic metallogenic belt in western Henan Province. We have studied the geological characteristics, halo element association and zoning characteristics of this deposit. The results suggest that the halo zoning sequence is a normal one as a whole, except the leading elements coexistent with the nearly mineral elements on the No.49 exploration line. The geochemical parameters reflect that the mineralization here has the characteristics of multi-phases and multi-stages, some parameters have the trend of increasing toward depth, same as the anomaly scale of Au and the near mineral elements, thus there may be a prospecting potential at depth. In combination with the primary halo axial zoning sequence, geochemical parameters and the characteristics of anomaly scale varying with the depth, the shallow prospecting target should be placed above the elevation of about 400m, while the deep one should be placed under the elevation of about 300m. |
