摘要: On airless bodies such as the Moon and Mercury, secondary craters on continuous secondaries facies of fresh mostly occur in chains clusters. They have very irregular shapes. Secondaries some Martian Mercurian are more isolated from each other distribution circular shape, probably due to effect target properties impact excavation process. This paper studies all lunar complex using recently-obtained high resolution images. After a global search, we find that 3 basins similar those Mercury: Orientale basin, Antoniadi crater, Compton crater. The morphological differences between special typical quantitatively compared analyzed. Our preliminary analyses suggest were caused by temperature gradients within local targets when these formed. high-temperature could affected process causing higher ejection angles, giving rise scattered secondaries.
