| 中文摘要: |
| 燕山东段与中酸性侵入体有关的金矿床,均产在特征的红、白花岗岩迭加成因的杂岩体内部或其邻近围岩中.位于马兰峪复背斜南、北两翼的牛心山、峪耳崖金矿床比较典型.本文根据大量的测试数据和野外资料,从地质学、岩石矿物学、岩石地球化学、同位素地质学、物理化学诸方面入手,对两矿床的矿化特征及成因演化进行了比较性和探索性的剖析.在此基础上,指出了矿化岩体的标志及找矿方向. |
| 英文摘要: |
| Niuxinshan and Yuerya gold deposits are the magma-hydrothermal type deposits related to remelted granite conplex of Yanshanian Period. They are similar in their genesis although some difference can be found. This paper correlates data of their gelolgical features, petrochemistry, trace element, geochemistry, REE, isotopes, rock assemblage and mineral association, alteration, Auenrichment pattern and source material based on which their genesis and evolution are discussed. Then mineralization, controling factors and further exploration targets for gold deposits related to Medium-acidic plutons in the eastern Hebei province are point out. |
