| 中文摘要: |
| 月牙山地区位于北山裂谷带内,成矿地质条件十分有利。文章在1∶5万水系沉积物测量的基础上,对月牙山地区的地球化学特征进行了初步分析。对该地区元素的地球化学参数进行计算,对元素分布特征、单元素异常特征、综合异常特征、元素相关性及异常元素组合特征进行了研究,认为区内寻找Au、Cu、Sb、As、W、Mo、Ni矿化体或矿床潜力较大,金、铜为研究区的主攻矿种。推断区内的成矿类型为构造蚀变岩型金矿和与基性(超基性)岩有关的铜多金属矿。并通过元素异常特征,结合成矿地质条件及已知矿化信息,划分了4个找矿远景区。 |
| 英文摘要: |
| The Yueyashan area is located in the Beishan rift zone,where there is favorable metallogenic geological conditions and great prospecting potential. Based on the 1∶50 000 stream sediment survey, the geochemical features in Yueyashan area was preliminarily analyzed. This paper highlighted characteristics of elemental distribution, anomaly of single element and anomalies of multi elementsand element correlation and anomaly assemblages. The results indicate that there might be a prospective area for Au, Cu, Sb, As, W, Mo and Ni mineralization or deposits in the study area. Furthermore, Au and Cu mineralization are probably main prospecitng targets. It is inferred that the gold mineralization is probably structural altered type and the copper mineralization is probably polymetallic deposit related to the basic and ultrabasic rocks in Yueyashan area. Finally five prospecting target areas were outlined based on study of element anomalous characteristics in combination with metallogenic geological conditions and known mineralization information. |
