【摘要】 内蒙乌拉山—大青山地区太古界混合岩化—重熔作用 ,随地质时代不同发育特征不同。上太古界乌拉山岩群主要发育重熔条带 ,局部出现重熔 ;中太古界集宁岩群有百分之五十发生了重熔 ;下太古界兴和岩群几乎全部被熔融 ,只残留了部分偏基性的难熔组分。现在的兴和岩群只代表兴和期火山—沉积岩石组合的一少部分。更多还原

【Abstract】 Archaean group of mingmatization - anatexis had different development features with different geological time in Wulashan-Daqingshan area, Inner Mongolia. Upper Archaean group of Wulashan rock suite mainly developed the anatectic streak that partial area appeared the anatexis. Middle Archaean group of Jining group had 50% of anatexis. Last part of Xinghe rock group almost had been fused that it only kept a partial basic hard composition. Now Xinghe rock suite only represents a small part of Xinghe time volcanic-sediment rock assemblage.更多还原
