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抬升速率，这是世界上抬升最快的地区之一。到目前为止，还没有其他研究成功地测量抬升速率，因为保留这一记录的年轻沉积岩通常会被迅速侵蚀掉。菲尼斯特尔山脉在保存非常年轻的(中新世至更新世)石灰岩盖子方面可能是独一无二的。为了区分隆升和侵蚀对山区地形的影响，隆升速率是一个必须测量的重要数值，这反过来又将阐明岩石圈动力学和造山过程。这一结果将对山脉地带的各种构造问题产生影响。

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.
