Abstract

The enigma of the apparently young crater retention age for the large lunar volcanic Irregular Mare Patch Ina (∼33.2 Myr) is critically analyzed through the review of: 1) experimental data on high velocity impacts into porous targets, 2) observed small impact crater morphology, and 3) the possible variation in small impact crater morphology with age. While we find that these different data sets and approaches could not unequivocally resolve the enigma, our analysis provides directions for new studies in several disciplines that are designed to help resolve the age conundrum and improve upcoming exploration mission goals and objectives.

月球伊纳不规则赤铁矿斑块（IMP）的撞击陨石坑：关于撞击多孔玄武岩基质性质的实验证据和悬而未决的问题

通过对以下方面的回顾，对月球大型火山不规则母斑伊娜（∼33.2 Myr）明显较年轻的撞击坑保留年龄之谜进行了批判性分析：1）高速撞击多孔目标的实验数据；2）观测到的小型撞击坑形态；3）小型撞击坑形态随年龄的可能变化：1) 高速撞击多孔目标的实验数据；2) 观测到的小型撞击坑形态；3) 小型撞击坑形态随年龄的可能变化。虽然我们发现这些不同的数据集和方法并不能明确地解决这个谜团，但我们的分析为多个学科的新研究提供了方向，这些研究旨在帮助解决年龄谜团并改进即将到来的探测任务目标和目的。
