| 中文摘要: |
| 文章通过对沂南县铜井铜金矿床深部地质特征的论述,阐明了深部矿体的赋存特征;通过同位素测定,分析了矿床的物质来源、形成温度、形成时间和矿床成因。认为铜井铜金矿是由铜井杂岩体,尤其是闪长玢岩、二长花岗斑岩沿层理或层间滑脱带侵入,与灰岩接触交代形成的夕卡岩型矿床。根据成矿地质特征建立了矿床的成矿模式。 |
| 英文摘要: |
| Occurrence characteristics of deep ore bodies of Cu-Au deposits in Tongjing area are presented on basis of description of deep geological characteristics of the deposits. Ore material source and formation temperature and time and genesis of them are determined by isotopic analysis. They are skarn type deposits resulted from metasomatism of limestone by intrusion of Tongjing complex, especially dioritic porphyrite, monzonitic granto-porphyry along the interformation detachment. According to the geological characteristics the metallogenic model is built. |
