Active Extension in an Arc-Continent Collision, Taiwan: A GPS, Structural and Geomorphic Investigation

9903248活动挤压造山作用中的Byrne伸展是违反直觉的，但已在几个山脉中记录在案。 在挤压构造环境中伸展力发展的情况下的理解在古代的例子中受到阻碍，因为这些特征的时间通常不够精确，无法建立同时代，应变积累也不活跃。 台湾造山带为开展这类工作提供了一个独特的机会，因为它是活跃的、可进入的、研究得比较好的，而且有大量的大地测量基础设施，包括区域范围的全球定位系统、水准测量和三角测量研究。该项目包括新的全球定位系统纪念碑和地貌研究。 结果包括一个新的，综合的数据集，以限制区域规模的结构的造山带和现代的模拟模型的延长提出了较老的，更深的侵蚀带的板块运动学不太好的约束。

9903248ByrneExtension in active compressional orogensis is counter-intuitive but has been documented in several mountain ranges. Understanding of the circumstances under which extensional forces develop in a compressional tectonic environment is hampered in ancient examples because timing of the features commonly is not sufficiently precise to establish contemporaientry, and strain accumulation is not active. The Taiwan orogenic belt provides a unique opportunity to conduct this type of work because it is active, accessible, relatively well studied and substantial geodetic infrastructure is available, including regional-scale GPS, leveling and triangulation studies. The project includes new GPS monuments and geomorphic studies. Results include a new, integrated data set to constrain the regional-scale architecture of the orogenic belt and a modern analogue for models of extension proposed for older, more deeply eroded belts where plate kinematics are less well constrained.
