全球1°×1°海洋岩石圈有效弹性厚度模型
|
Abstract:
利用岩石圈挠曲均衡原理，联合海底地形模型和测高重力异常数据，采用滑动窗口导纳技术（moving window admittance technique，MWAT）计算了全球1°×1°海洋岩石圈有效弹性厚度模型。结果表明，海洋岩石圈有效弹性厚度总体较小，10 km以下区域约占70%，15 km以下约占85.4%，均值和标准差分别约为10 km和6.7 km。岩石圈有效弹性厚度20 km以上的区域主要位于海沟外隆地区，洋中脊岩石圈有效弹性厚度一般小于5 km；被动大陆边缘，如澳洲大陆南缘，岩石圈有效弹性厚度一般也较小；太平洋的海山密集分布地区，岩石圈有效弹性厚度一般为10~20 km
