3裂谷的形成与演化计划3.3北美洲东部边缘——主要研究区3.3.1背景和动力:与RIE问题的关系被动的裂谷系统在裂谷过程中扮演了重要角色,因为它们包括了整个地质学历史的记录,从裂谷开端、大陆裂解、海底扩张以及最后的成熟边缘。RIE起始的目标如同地学棱镜科学计划草案(DSP)所描述,是了解裂谷初始如何进行,驱动裂谷的过程如何相互作用和演化,这些过程如何导致特别的裂谷架构,什么是裂谷期和后裂谷期边缘演化 3.3 The Rift Formation and Evolution Program 3.3 The North East Coast of the East - Main Study Areas 3.3.1 Background and Motivation: Relation to RIE Issues Passive rifting systems play an important role in rifting as they include the entire Records of the history of geology, from the beginning of the rift, the fragmentation of the mainland, the expansion of the seabed, and the final maturity margin. The goal of the RIE initiative, as described in the Geosciences Prism Scientific Draft (DSP), is to understand how rifting initially interacts and evolves the processes that drive rifting, how these processes lead to particular rift structures and what are rifts Marginal and post-rift marginal evolution
