Surface Uplift History of the Finisterre Mountains, Papua New Guinea

这项研究将测量巴布亚新几内亚北部菲尼斯特雷山脉的地表隆起率，这是世界上上升最快的地区之一。迄今为止，还没有其他研究成功地测量了隆起速率，因为保留记录的年轻沉积岩通常会迅速被侵蚀掉。菲尼斯特雷山脉可能在保存非常年轻（中新世至更新世）的石灰岩盖层方面是独一无二的。抬升率是一个重要的测量量，它可以区分抬升和侵蚀对山脉地形的影响，从而阐明岩石圈动力学和造山过程。这些结果将对山带中各种各样的构造问题产生影响。

This study will measure surface uplift rates of the Finisterre Mountains of northern Papua New Guinea, one of the fastest uplifting areas in the world. No other study to date has succeeded in measuring uplift rates because the young sedimentary rocks that retain the record are usually rapidly eroded away. The Finisterre Mountains may be unique in preserving a very young (Miocene through Pleistocene) limestone cap. The uplift rate is a crucial quantity to measure in order to separate uplift versus erosion effects on mountain topography, which in turn will clarify the processes of lithospheric dynamics and mountain building. The results will have implications for a wide variety of tectonic problems in mountain belts.
