| 中文摘要: |
| 华北地区铜矿资源丰富，文章在对华北地区579处铜矿床（点）资料系统梳理的基础上，总结了区内矿床类型，划分出四大成矿期，认为侏罗纪—白垩纪为最主要的成矿时期，以斑岩型、接触交代型为主；提出不同类型铜矿时空分布特征及控矿因素；建立了7种预测类型划分方案、6种预测方法。探讨了华北地区铜矿的时空演化，认为在重要成矿带和典型矿床开展深部资源勘查是实现找矿突破的重要途径。 |
| 英文摘要: |
| North China is abundant with Copper resources. Based on the data of 579 copper ore deposits and occurrences, we summarized the copper deposits types and they are formed in three metallogenic epochs. The Jurassic-Cretaceous period is the the most important metallogenic epoch and the copper deposits are dominated by porphyry and skarn copper deposits. Spatial and temporal distribution and control factors for different copper deposits and 7 prediction types and 6 prediction methods are proposed. The spatial and temporal distribution evolution of the copper deposits is discussed and carrying out copper ore prospecting to depth of the known copper deposits is considered to be the key to make copper ore prospecting breakthrough in the North China. |
