Analysis of Fold and Thrust Belt Kinematics in the Central Brooks Range, Northern Alaska

阿拉斯加布鲁克斯山脉的构造框架 一直是最近研究的焦点，这次更新将建立在 这项工作 一些基本问题将得到解决。 一是形成明显的错序逆冲断层 在褶皱冲断带的内部 另一个是 主要伸展构造作用的时间和运动学关系 不断向北推进 还需要研究的是 与反向剪切有关的晚期构造， 在山脉中心形成一个大规模的复式结构。 这些是大多数褶皱冲断带的断层特征， 这项工作将适用于其他例子，以及 对阿拉斯加地质的了解

The structural framework of the Brooks Range, Alaska has been the focus of recent research, and this renewal will build on this work. A number of fundamental problems will be addressed. The first is the formation of an apparent out of sequence thrust in the interior of the fold and thrust belt. Another is the timing and kinematic relationship of major extensional tectonism with progressive north-directed thrusting. Also to be studied are late-stage structures associated with antithetic shear and the formation of a large scale duplex in the center of the range. These are fall features of most fold and thrust belts, and results of this work will be applicable to other examples, as well s to the understanding of Alaskan geology.
