The Carthage-Colton Shear Zone, Grenville Orogen NY

9627911 VanderPluijm近年来的工作表明，伸展构造在收缩过程中形成，尤其是在收缩之后立即形成，特别是在年轻造山带中，在高构造层次上。有迹象表明，东海岸的格伦维尔造山活动也同样涉及延伸区，因此该项目将在此之后进行。迦太基-科尔顿剪切带标志着格伦维尔变质沉积带的最东端边界，并保存了晚期伸展历史的证据。这些结果不仅将澄清阿迪朗达克山脉的格伦维尔历史，而且有望提供对造山演化的地壳深部过程的本质的洞察。

9627911 VanderPluijm Work in recent years, particularly in young orogens, and at high structural levels, has shown that extensional structures form during and especially immediately following contraction. This project will follow indications that extension was similarly involved in the Grenville orogeny of the eastern seaboard. The Carthage-Colton shear zone marks the easternmost boundary of the Grenville Metasedimentary belt and preserves evidence of the late-stage extensional history. Results will not only clarify Grenville history of the Adirondacks but are expected to offer insights into the nature of deep-crustal processes doing orogenic evolution.
