| 中文摘要: |
| 东秦岭位于华北板块与扬子板块之间的拼合带--秦岭造山带东段,该区是一典型的地球化学急变带与地球物理梯度交叉区,壳幔富含Cu、Pb、Zn、Au、Ag、W、Mo元素,为一元古宙一古生代裂陷槽,熊耳群、宽坪群、二郎坪群、耀岭河组火山岩系中的火山喷发Cu、Pb、Zn、Ag、Au矿(化)层.多期次的构造岩浆活动,使区内Cu、Pb、Zn、Ag、Au、W、Mo叠加富集体成矿,从而使东秦岭地区铜矿床在区域分布、成矿空间、时间上呈现出一定的规律性并找矿标志明显. |
| 英文摘要: |
| The eastern Qinling or eastern part of Qinling orogenic belt is located at matching belt between North China platform and Yangtze platform.The area is a typical geochemical leap belt and a geophysical gradient intersect.The mantle and crust beneath the area are enriched in Cu,Pb,Zn,Ag,Au and Mo.The belt belongs be Proterozoic and Paleozoic rift zone.Volcanic rocks of Xiong'er Group,Kuanping Group,Erlangping Group,and Yaolinghe formation are source beds for Cu,Pb,Zn,Au and Ag mineralization.Multiple magmatism made enrichment and mineralization for Cu,Pb,Zn,Ag,Au,W and Mo.Distribution,mineralizing situation and time of Cu deposits in the eastern Qinling exist definite rules with obvious ore prospecting indicator. |
