Ductile extension model of rift basin and its application in Bohai Bay Basin

  • 裂陷盆地在拉张过程中存在的韧性变形一直没有得到理论界的关注。两种常用的伸展量计算方法("地壳厚度变化计算法"和"断层平衡复原法")的巨大差异是由于盆地的韧性伸展分量导致的。本文建立了一套基于以上两种方法耦合应用的盆地韧性伸展量和断层滑移伸展量计算模型,并应用于渤海湾盆地。经计算,渤海湾盆地的韧性伸展量大约占总伸展量的40%左右,这是用"断层平衡复原法"计算的伸展量总是小于"地壳厚度变化计算法"计算的伸展量的真正原因。渤海湾歧口凹陷的伸展计算结果显示韧性变形速率与断层滑移速率呈正比关系,盆地在裂陷期不仅断层滑移剧烈,韧性变形速率也很大。
