| 中文摘要: |
| 赤湖铜钼矿是东天山地区典型的斑岩型铜钼矿床,赤湖地区地表原生晕异常规律的研究表明赤湖及赤湖东地区地表原生晕异常分布特征符合斑岩型铜钼矿的矿致异常结构,即由矿体(矿化体)引起的成矿元素Cu、Mo异常出现在As、Sb、Au、Ag、Pb、Bi等元素异常中相对弱异常部位,从而构成内部为Cu、Mo,外部为As、Sb、Au、Ag、Pb、Bi等的“致矿异常结构”。这一异常结构特征实际上是斑岩型矿床“原生晕”在元素分带上的反映,该原生晕异常特征显示赤湖东地区同样具有较好的斑岩型铜钼矿找矿前景。 |
| 英文摘要: |
| The Chihu Cu-Mo deposit is a typical porphyry deposit in the East Tianshan area. This paper focus on the study on the abnormality of primary haloes.The results prove that the distribution characteristics of primary halo anomalies of the Chihu and the east Chihu area are according to the ore-indicating geological anomaly of typical porphyry deposits, namely, the anomaly of Cu-Mo are appeared on the relatively weak area of the anomalyofAs-Sb-Au-Ag-Pb-Bi, therebyforming an abnormal structure that from the inner Cu-Mo abnormity to the outer As-Sb-Au-Ag-Pb-Biabnormity. This type of anomalous structure is actually a reflection of the element zoning of porphyry depositThis abnormality of primary haloes of indicate that the east Chihuareahas a good prospecting prospect for porphyry Cu-Mo deposit, and is also meaningful to search the same type deposit in the east tianshan area. |
