| 摘 要： | 北山岩群是一套经角闪岩相主期变质作用和绿帘角闪岩相退变质作用的强变质变形地体.据岩石组合特征可划分为4个岩组:第一岩组为斜长角闪片岩夹黑云斜长片麻岩和变粒岩;第二岩组为片麻岩夹斜长角闪片岩、石英片岩、变粒岩；第三岩组为石英片岩夹大理岩、石英岩；第四岩组为石英岩夹石英片岩.经原岩恢复,第一岩组原岩主要为板内拉斑玄武岩,具向岛弧玄武岩过渡趋势；第二岩组原岩为快速沉积的碎屑岩和酸性火山岩；第三岩组原岩为碎屑岩夹碳酸盐岩；第四岩组原岩为成熟度较高的碎屑岩.据火山岩组合、碎屑组合岩特征及地球化学特征,判断其形成年代为早元古代,构造环境为早期裂谷发育速度较快,火山活动强烈,沉积物为快速沉积的碎屑岩;后期构造趋于平缓,碎屑岩成熟度升高,并夹有厚层碳酸盐岩. |

| Abstract: | Beishan group is a suit of strong metamorphic terrane which was suffered amphibolite facies main metamorphism and epidote-amphibolite facies fade metamorphism.According to characteristics of rock combination,the group can be divided into four formations.The first formation is mainly composed of amphibolite schist interclated with biotite-plagioclase gneiss and minor fles.The second formation is composed of gneiss interclated with amhpibolite schist,quartz schist,and minor fels.The third formation is compose... |
