| 摘 要： | 细碧—角斑岩系一般分为细碧岩、角斑岩和石英角斑岩三类。其形成的大地构造背景多样 :包括洋中脊、岛弧、弧后盆地、陆裂作用导致的小洋盆等 ,原始岩浆来自于上地幔及下地壳的深熔作用。它是海底火山岩经埋藏变质、循环热海水与岩石的交换反应在内的广义洋底变质作用长期改造的最终产物 ,之后还可遭受造山作用的变形变质作用的改造

| Abstract: | Spilite keratophyre sequence is generally divided into spilite, keratophyre and quartz keratophyre. The geotectonic background of forming the rock sequence includes oceanic ridge, island arc, back arc basin, and small ocean basin etc.. The rock sequence is resulted from that submarine volcanic rocks reacting with circling hot sea water and experiences transformation of metamorphic deformation. |
