- Hargraves is a Hesperian-age complex double-layered ejecta impact crater on Mars. It was emplaced near the crustal dichotomy in the vicinity of the Nili Fossae, the Syrtis Major volcanic plains, and the Isidis impact basin, and is situated within the Syrtis Major quadrangle. Hargraves has been the target of focused study because its ejecta apron is particularly well-preserved for a Martian crater of its size. It has been analogized to similar double-layered ejecta blankets on Earth, including that of the Ries impact structure, which was where the conceptual model for how such craters formed was first advanced. The presence of Hargraves ejecta in a trough of the Nili Fossae to its west, contributed to a consideration of the Nili Fossae as a possible candidate landing site for NASA's Perseverance rover. The presence of certain minerals (phyllosilicates, serpentine, and magnesite) detected remotely in Hargraves ejecta imply aqueous alteration either at the time of the Hargraves impact or by virtue of a hydrothermal system active after impact.

- 哈格雷夫斯陨击坑（Hargraves）是火星大瑟提斯区一座形成于赫斯珀里亚纪时期的复杂双层喷射物撞击坑。它位于大瑟提斯火山平原及伊希斯撞击盆地内尼利堑沟群靠近地壳分界区附近。哈格雷夫斯一直是火星上的重点研究目标，因为它的喷射物覆盖层在火星同类陨坑中保存得尤为完好，并被比作地球类似物的双层喷射覆盖层，如首个作为此类陨坑形成模型的。 出现在该陨坑西面尼利堑沟群一条槽沟中的喷射物，促使人们考虑将尼利堑沟群列为美国宇航局“毅力号”漫游车的候选着陆点。在喷出物中远程检测到的某些矿物（页硅酸盐、蛇纹石和菱镁矿）代表在哈格雷夫斯坑撞击时或撞击后因活跃的热液系统而发生的水蚀变。 (zh)
