沿辐合边缘的脊状俯冲的变质和构造后果尚不为人所知,但其意义重大,因为几乎所有的辐合边缘最终都会吞噬一个扩张中心。EAR90-18717和EAR90-20391的合作项目将研究Chugach变质杂岩,该杂岩具有几个不寻常的特征,可以归因于第三纪的脊俯冲。工作重点将放在异常的低P、高T变质作用以及伴随该变质组合形成的构造和运动背景上。研究结果将为与脊俯冲有关的构造构造提供一个通用模式。
英文摘要
The metamorphic and structural consequences of ridge subduction along a convergent margin are not well known, but is significant because virtually all convergent margins will ultimately consume a spreading center. This collaborative project between EAR90-18717 and EAR90-20391 will examine the Chugach metamorphic complex which possesses several unusual features that can be attributed to ridge subduction in the Tertiary. Work will focus on the anomalous low P, high T metamorphic and the structural and kinematic setting which accompanied the formation of this metamorphic assemblage. Results will lead to a general model for ridge subduction-related tectonics.
