Tectonic models have focused on explaining how orogenic belts initiate and develop in terms of plate interactions, but the related problem of how orogenies end has received relatively little attention. This project will address this issue by a detailed study of the circumstances of the ending of the Taconic orogeny in New England, and will involve extensive radiometric age dating. These and extensive existing geological data for this area will be utilized in testing several models of how orogeny terminates. Results are expected to applicable to the general problem.

构造模型的重点是解释造山带如何在板块相互作用方面开始和发展，但造山作用如何结束的相关问题却很少受到关注。该项目将通过详细研究新英格兰塔科尼奥峰结束的情况来解决这个问题，并将涉及广泛的放射性年龄测定。这些以及该地区现有的大量地质数据将用于测试几种关于地壳如何终止的模型。期望所得结果能适用于一般问题。
