| 中文摘要: |
| 肉早某日地区位于东昆仑造山带东段，是重要的金及多金属成矿区。本文在充分了解区域基础地质资料的前提下，对肉早某日地区1∶5万水系沉积物地球化学测量中的元素进行分析并对数据进行系统检查和特征统计。通过相关分析、聚类分析、因子分析方法确定出与成矿密切相关九种元素Ag、Au、Cu、Zn、Pb、Fe、Cr、Co、Ni。通过对数据剔值处理和累频分析确定异常下限，圈定单元素异常和综合元素异常。根据单元素异常特征并结合地质特征，进行综合异常评价，共圈定6处综合异常，圈定重点靶区3个并对其进行了概述。 |
| 英文摘要: |
| Rouzaomouri area is located in the eastern part of the East Kunlun orogenic belt and is an important gold and polymetallic metallogenic belt. Based on full comprehension of the regional basic geological data analysis is made to elements and systematic check to data and statistics to the characteristics. Correlation analysis, cluster analysis and factor analysis show that nine elements, Ag, Au, Cu, Zn, Pb, Fe, Cr, Co and Ni are closely correlated to mineralization. The lower limit of anomaly is determined by data rejection and cumulative frequency analysis and used to delineate single element anomaly and comprehensive element anomaly. Then, according to the characteristics of single element anomaly and the geological characteristics the anomlies are evaluated and 6 comprehensive anomlies are lineated of which three are determined targets and described in detail. |
