Thermochronology and Thermobarometry in Lithotectonic Zones in Eastern New England

新英格兰东部现在被认为是由许多外来的地体组成，这些地体沿着大断层与祖先北美相连。然而，这些地形的增加时间处于不断变化的状态。该项目将从这些岩层边界断层的两侧收集温度和气压数据，并结合现有的年龄测定，评估阿勒格尼期大运动的可能性，这是以前没有认识到的。结果有可能为新英格兰地区的地层增生时间提供重要的重新解释。

Eastern New England is now recognized to consist of a number of exotic terranes joined to ancestral North America along large faults. However, the timing of the accretion of these terranes is in a state of flux. This project will gather thermometric and barometric data from both sides of these terrane bounding faults and together with existing age determinations will assess the possibility of major Alleghenian motion, not previously recognized. Results have the potential to provide a major re-interpretation of the timing of terrane accretion in New England.
