| 中文摘要: |
| 青海省锡铁山铅锌多金属矿床是青海省内重要的大型铅锌多金属矿床,矿区边部找矿潜力巨大。但由于整个锡铁山成矿带面积较大,所涉及图幅数量过多,数据库过大,导致前期取得的大量化探基础资料不能全面进行系统地分析研究,而采用传统的化探成图方法不能全面地反映真实的化探异常结果,影响找矿效果,这极大地制约了更深层次找矿成果的取得和后备基地的优选。文章在前人研究成果的基础上,利用衬值法对已有化探数据进行系统地分析处理,克服了常规化探成图方法的不足,通过与常规化探成图方法的对比研究,证明利用衬值法来进行大数据化探处理是切实可行的。 |

| Xitieshan metallogenic belt is a important Pb-Zn polymetallic metallogenic belt in Qinghai province, its prospecting potential is tremendous.But because the whole area is rather larger, the databases are also very large, a lot of geochemical datas can not be analyzed systematically, and using the traditional geochemical mapping method can not fully reflect the real results of geochemical anomalies and influence prospecting effect, this greatly restricted the ore-prospecting achievements and reserve optimization. In this paper, on the basis of predecessors’ research results, the method of contrast values is used to process systematically analysis on geochemical data to overcome the disadvantages of conventional geochemical mapping method.Comparing with the conventional geochemical mapping method of research, the method of contrast values for geochemical exploration data processing is more feasible. |
