Integrated Kinematic,Geothermobarometric,and Isotopic Studies of the Yukon-Tanana Terrane: Constraints on Its Petrotectonic Evolution and Implications for Early....

Yukon-Tanana火山岩，一个广泛的变质-深成岩 组合，暴露在阿拉斯加中东部和南部 育空地区，并形成了基本边界之间的土著 产于北美洲和外侧加积的白垩纪地层。 这 该项目将测试一个与俯冲有关的走滑模型 在育空地区的Teslin缝合带内， 互补运动学、地质温压学和同位素， 分析相关岩石。 结果应适用于更深层次的 这些俯冲系统的部分具有显著的走滑 件.

The Yukon-Tanana terrane, an extensive metamorphic-plutonic assemblage, is exposed in east-central Alaska and southern Yukon, and forms the fundamental boundary between antochthonous strata of North American and outboard accreted terrane. This project will test a model of subduction-related strike-slip translation developed within the Teslin suture zone, Yukon by complementary kinematic, geothermobarometric, and isotopic and analyses of involved rocks. Results should apply to deeper parts of those subduction systems having significant strike-slip components.
