    Petrochemistry, Chronology and Tectonic Setting of Strong Peraluminous Anatectic Oanitoids in Yunkai Orogenic Belt, Western Guangdong Province, China

    • 摘要: 云开造山带条带—眼球状(环斑)深熔花岗岩(含紫苏花岗岩)地球化学和年代学的研究表明, 绝大多数花岗岩的A/CNK > 1.1, CaO/Na2O=0.62-1.61(平均0.94, 大于0.3), Al2O3/TiO=16.6-60.6(平均23.68), 高场强元素Ta、Nb、Zr亏损, 具大陆边缘俯冲-碰撞造山带后碰撞构造环境强过铝(SP)高钾钙碱性-钙碱性花岗岩的特征, 紫苏花岗岩和片麻状含榴黑云二长花岗岩Al2O3/TiO(平均17.82)明显低于条带-眼球状(环斑)黑云二长花岗岩Al2O3/TiO(平均29.55), 显示其形成温度更高, 并具A型花岗岩的演化特征.而且从高钾钙碱性条带-眼球状(环斑)黑云二长花岗岩到钙碱性紫苏花岗岩、片麻状含榴黑云二长花岗岩, 形成时代由(465±10)Ma、(467±10)Ma变为(435±11)Ma、(413±8)Ma, 表明扬子板块与华夏板块在加里东期发生了洋—陆俯冲—碰撞造山和后碰撞的伸展—拆沉—底侵岩浆岩作用, 并且后期又经历了海西—印支期挤压抬升和伸展揭顶作用的改造, 这也为华南存在加里东期扬子板块向华夏板块的洋-陆俯冲-碰撞造山提供了重要证据.
