地球物理资料所揭示的南海东北部中生代俯冲增生带
|
摘要
根据新处理的重、磁和广角地震图件的解释,推测在南海北部从台西南盆地到深海盆北缘存在一条大致NE45°走向的中生代俯冲增生带.主要依据包括:台西南-中沙东布格重力异常总梯度峰值带在强度和规模上都与马尼拉海沟俯冲增生带引起的总梯度峰值带相近;该峰值带与海底地形和新生代构造都斜交,指示前新生代构造;该峰值带被NW向断层左行错断成雁列状,符合中生代区域应力场特征;其西北方在陆架区有与之大致平行的高磁异常带,指示中生代火山弧.此外,海底地震仪资料显示在俯冲增生带位置上出现北倾陡坎、海底地震仪和长电缆反射地震剖面都显示相应部位出现双莫霍面叠置,也可作为佐证.这段中生代俯冲增生带的发现正好填补了欧亚大陆东南缘晚中生代俯冲增生带在南海东北部的一段空白.
