| 中文摘要: |
| 通过依托项目“青海省杂多县阿涌地区1∶5万水系沉积物测量”的实施和综合研究,获得了较丰富的化探资料。对18种元素进行了统计分析,基本阐明各元素富集离散特征和地球化学空间展布规律,利用聚类分析和R型因子分析,讨论了各元素之间的组合关系；结合构造、地层及成矿带特征,对该区主要成矿元素分布有了进一步认识。依据元素组合、异常分布、新发现的矿化线索等特征的分析,在该区内初步划分了5个远景区,15处找矿靶区。为该区应用地球化学异常开展成矿预测和找矿提供依据。 |
| 英文摘要: |
| By the implementation and integrated study of the stream sediment survey at the scale of 1∶50 000 in the Ayong area,Zaduo county,Qinghai Province, the abundant geochemical data were obtained. Statistical analysis was conducted for the 18 elements, the enrichment and dispersion characteristics and the geochemical spatial distribution of these elements were explained by using cluster analysis and R-factor analysis, the relationship among these elements is discussed. In combination with structures, strata and metallogenic characteristics in the study area, the distribution of main ore-forming elements was well known. Based on element combination, abnormal distribution characteristics, the newly discovered mineralization clues, five prospective areas and 15 prospecting targets were preliminary outlined which provides the valuable evidence for further prospecting and metallogenic prediction by the application of geochemical anomaly |
