How Do Orogenies End? A Case Study From the Taconic Orogen

构造模型主要是从板块相互作用的角度来解释造山带是如何开始和发展的，而造山带如何结束的相关问题却很少得到关注。该项目将通过详细研究新英格兰Taconic造山运动结束的情况来解决这一问题，并将涉及广泛的放射性年龄测定。这些和该地区广泛的现有地质数据将用于测试几个造山运动如何结束的模型。结果有望适用于一般问题。

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.
