摘要:
?啾ι降厍挥诖笮税擦胫斜辈慷啾ι健⒍酵猓┏煽蟠侵泄狈街匾陌哐倚屯蟛亍Ｔ谘芯壳沽?∶5万水系沉积物测量，对1 391件样品11种元素进行了测试分析，通过分析地球化学参数特征、元素组合特征，圈定单元素异常162处，组合异常18处，确定Au、Ag、Cu、Mo为主成矿元素。根据成矿地质条件、地球化学异常特征，在研究区划分了多宝山—铜山铜钼成矿远景区、争光金成矿远景区、根里河钼钨成矿远景区。

Abstract:
Duobaoshan area,located in Duobaoshan-Aershan copper(molybdenum) metallogenic belt in the central and northern part of the Greater Khingan Mountains，is an important porphyry copper ore source area in North China.The 1∶50 000 stream sediment survey was carried out in the study area,analyzing 11 elements in 1 391 samples.By analyzing geochemical parameters and element assemblage characteristics,162 single anomaly elements and 18 assemblage anomaly elements were delineated,and Au，Ag，Cu and Mo were determined to be the major ore-forming elements.According to the geological conditions for mineralization as well as characteristics of anomalies,the study area was pided into Duobaoshan-Tongshan copper and molybdenum metallogenic prospective area，Zhengguang gold metallogenic prospective area and Genli River molybdenum and tungsten metallogenic prospective area.
