火星与亚利桑那州Moenkopi高原的古代河流形态特征

Ancient River Morphological Features on Mars versus Arizona Moenkopi Plateau

Antonio Paris, Laurence Tognetti

摘要:

火星目前是关于地球上拟议的古代河流形态景观的科学辩论的中心。因此,人们对火星地貌及其水历史的好奇心越来越强,这促使人们努力更好地了解这些景观是如何形成的。然而,许多研究都是拼凑的调查,没有从地球模拟的角度彻底研究火星上的古代河流过程。因此,这项调查的目的是将莫恩科皮高原上已知的河流特征与火星上拟议的古河流特征进行比较。沿着Moenkopi高原寻找类似物是由于河流侵蚀的相似性,受风沙活动的影响和修改,主要是从二叠纪到侏罗纪。通过分析来自NASA火星勘测轨道飞行器高分辨率成像科学实验和上下文相机上的两个相机的轨道图像,并将其与美国地质调查局和在Moenkopi高原上空运行的无人驾驶飞机获得的图像进行平行,这项调查确定了类似的河流形态。因此,我们解释说,这两颗行星上发生了相同的河流过程,从而加强了火星上水的历史。

英文摘要:

Mars is currently at the center of scientific debate regarding proposed ancient river morphological landscapes on the planet. An increased curiosity in the geomorphology of Mars and its water history, therefore, has led to an effort to better understand how those landscapes formed. Many studies, however, consist of patchwork investigations that have not thoroughly examined proposed ancient fluvial processes on Mars from an Earth analog perspective. The purpose of this investigation, therefore, is to compare known fluvial features on Moenkopi Plateau with proposed paleopotamologic features on Mars. The search for analogs along the Moenkopi Plateau was due to the similarities in fluvial erosion, influenced and modified by eolian activity, primarily from Permian through Jurassic age. By analyzing orbital imagery from two cameras onboard NASA Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment and the Context Camera and paralleling it with imagery obtained from the U.S. Geological Survey and an unmanned aircraft operating over the Moenkopi Plateau, this investigation identified similar fluvial morphology. We interpret, therefore, that the same fluvial processes occurred on both planets, thereby reinforcing the history of water on Mars.
