| 中文摘要: |
| 巴西巴伊亚州阿巴伊拉地区属于巴西热带干湿润季风高原中低山丘陵景观区之一,具巴西东部典型地质景观特征。通过在该区开展了野外水系沉积物采样介质粒度试验和室内分析及数据处理,确定了适合此景观区内1：10万水系沉积物测量最佳采样介质在－10目～+60目,用此粒级的采样介质圈定的成矿元素异常强度较高,并且较好地反映出试验区成矿元素地球化学异常。该采样粒级可以在巴西同类地区推广使用。 |
| 英文摘要: |
| The abaira area of Bahia Province in Brazil is one of wet monsoon climate and hills of altiplano landscape areas, with the typical geological characteristics of the east of brazil.Through the experimentation of mesh of stream sediment sampling,laboratory analysis and data processing,We determined the reasonable stream sediment sampling is -10～+60 mesh, moreover, with this mesh of stream sediment sampling, the result indicate that the intensity of ore-forming element anomalies are clearer and better reflect metallogenic element geochemical anomaly in the test area .This mesh of stream sediment sampling can be extensively employed in similar landscape areas of brazil. |
