项目摘要
Theoretical models of motion transfer from the ductile lower lithosphere and mantle upward through the brittle-ductile transition and the brittle upper crust are as yet inadequate to account for many phenomena, partly because of lack of access to intact crust sections that represent deformation results from the same overall tectonic environment. This project utilizes the Caribbean-South America plate boundary, which has been the locus of oblique convergence for the past 50 million years to address this problem. This system has brought a sequence of rocks to the surface that represent a continuous vertical section of the crust exposed from west to east along the contact between the two plates from Venezuela to Trinidad. Structural and thermochronologic data will be collected and used to develop, refine and test models for the origin, response partitioning, and exhumation of this sequence. Results have the potential to place significant constraints on rheological differences within the lithosphere, which is of fundamental importance in understanding tectonic systems and plate interactions.
从韧性较强的下岩石圈和地幔向上通过脆性-韧性转变和脆性上地壳的运动转移的理论模型还不足以解释许多现象,部分原因是缺乏完整的地壳剖面,这些剖面代表了同一整体构造环境造成的变形。这个项目利用加勒比海-南美洲板块边界,在过去的5000万年里,它一直是斜辐合的轨迹,来解决这个问题。这个系统将一系列岩石带到了地表,这些岩石代表了地壳的一个连续的垂直部分,沿着委内瑞拉到特立尼达的两个板块之间的接触从西到东暴露出来。将收集构造和热年代学数据,并用于开发、完善和测试该序列的起源、响应划分和发掘模型。结果有可能对岩石圈内的流变差异施加重大限制,这对理解构造系统和板块相互作用具有根本的重要性。
