简介：火星上有水的历史的证据记录在地表暴露的沉积岩的沉积特征和地层中。特别令人感兴趣的是与水道特征相关的沉积扇，因为在地球上，它们可能与构造（和气候）过程有关[例如1，2]。然而，在火星上，同构造沉积的好例子很少。我们以前[3，4]在火星Coprates Catena的两个小的封闭峡谷中进行了阶梯式风扇和层状硅酸盐材料的研究。在这项研究中，我们专注于更大的风扇和bajadas经历了沉降，通过反复的正常断层，这对理解构造，侵蚀和沉积过程之间的相互作用，在这个和更广泛的水手谷地区的影响。
Introduction: Evidence of the history of water on Mars is recorded in the sedimentary characteristics and stratigraphy of sedimentary rock exposed at the surface. Of particular interest are sedimentary fans associated with channel features, as on Earth they can be related to tectonic (and climatic) processes [e.g. 1,2]. On Mars however, few good examples exist of syntectonic sedimentation. We have previously [3,4] carried out studies of stepped fans and phyllosilicate material in two small closed canyons in Coprates Catena, Mars. In this study, we focus on larger fans and bajadas that have undergone subsidence through repeated normal faulting, which have implications for understanding the interplay between tectonic, erosional and depositional processes in this and the wider Valles Marineris region.
