黑龙江多宝山地区水系沉积物地球化学特征及成矿远景区划分
|
摘要
多宝山地区位于大兴安岭中北部多宝山—阿尔山铜(钼)成矿带,是中国北方重要的斑岩型铜矿产地。在研究区开展了1∶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。
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 divided into Duobaoshan-Tongshan copper and molybdenum metallogenic prospective area, Zhengguang gold metallogenic prospective area and Genli River molybdenum and tungsten metallogenic prospective area.
