Surface Uplift History of the Finisterre Mountains, Papua New Guinea

这项研究将测量菲尼斯特雷的表面隆起率 巴布亚新几内亚北方的山脉，是世界上海拔最高的山脉之一 最令人振奋的地区 迄今为止，没有其他研究 成功地测量了隆起率，因为年轻的沉积物 保留记录的岩石通常很快就被侵蚀掉了。 菲尼斯特雷山脉可能是独一无二的， （中新世至更新世）石灰岩帽。 隆升速率为 一个关键的测量量，以区分隆起和 侵蚀对山区地形的影响，这反过来又将澄清 岩石圈动力学和造山运动的过程。 的 结果将对各种构造 山区的问题。

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.
