Morpho-stratigraphic map of Jezero crater landing area

The rover Perseverance of the Mars2020 mission will depart to Mars in July 2020 and land on Mars in February 2021. Its landing site, Jezero crater, has been selected due to the presence of two fan deltas, inlet and outlet valleys and a huge number of aqueous landforms (fluvial and lacustrine sediments). This morpho-stratigraphic map has been produced from orbital visible imagery and its interpretations take into account the orbital facies (layers, massive, etc.) and their stratigraphic relationships, the texture and albedo of terrains, without taking into account mineralogical data. The area studied here is centered around the landing area comprising the east of the fan delta and the west of the crater floor. The map has been done at 1:10,000 scale.火星2020任务的毅力号（Perseverance）火星车将于2020年7月发射升空，并于2021年2月登陆火星。其着陆点杰泽罗撞击坑（Jezero crater）之所以被选中，是因为该区域存在两处扇三角洲、入水口与出水口峡谷，以及大量水成地貌（包括河流与湖相沉积物）。 本地貌地层图基于轨道可见光影像制作，解译过程充分考量了轨道相特征（层理、块状结构等）及其地层接触关系、地表纹理与反照率，未纳入矿物学数据。本次研究区域以着陆区为中心，涵盖扇三角洲东部与陨石坑坑底西部区域，制图比例尺为1:10000。
