| 中文摘要: |
| 安徽萧县前欧盘铅锌金矿预查区位于1∶2.5万航磁异常南西部边缘。该区以往1∶20万化探工作圈出了具有进一步工作意义的铜、铅异常。由于当时技术设备不完善,导致该区部分大比例尺物化探工作质量较差,没能达到普查工作的目的。本文目的是在收集研究区已有的物探资料及地质信息的基础上,了解研究区地表以下地层变化特征,圈出下一步工作的靶区。首先运用1∶1万地面高精度磁测缩小找矿范围,然后在靶区配以大功率激电测深、钻探测井等物探方法进行验证,以及对收集到的资料进行综合分析；大致查明该区地层、构造、岩浆岩、蚀变与矿化等特征并取得了研究区地层岩性物探成果资料,为下一阶段工作指明研究方向。 |

| Qianeuropan lead zinc gold deposit in Xiaoxian County, Anhui Province is located in the south western margin of 1:25000 aeromagnetic anomaly. In the past 1∶200000 geochemical exploration work in this area, copper and lead anomalies with further significance have been delineated. Due to the imperfection of technical equipment at that time, the quality of large-scale geophysical and geochemical exploration in this area was poor, which failed to achieve the purpose of general survey. The purpose of this paper is to collect the existing geophysical data and geological information in the study area, to understand the characteristics of stratigraphic changes under the surface of the study area and to delineate the target area for further work. Firstly, 1∶10000 surface high-precision magnetic survey is used to narrow the prospecting scope, then the target area is verified by high-power IP sounding, drilling logging and other geophysical methods, and the collected data are comprehensively analyzed; the characteristics of stratum, structure, magmatic rock, alteration and mineralization in this area are roughly identified and the results of stratum lithology geophysical exploration in this area are obtained. Point out the research direction for the next stage. |
