| 内容記述 | Crater size reflects the target response to the combined effects of impactor size, density, and velocity. Isolating the effects of each variable in the cratering record is generally considered masked, if not lost, during late stages of crater modification (e.g., floor uplift and rim collapse). Important clues, however, come from the distinctive signatures of the impactor created by oblique impacts. In summary, oblique impacts allow for the identification of distinctive signatures of the impactor created during early penetration. Such signatures may further allow first-order testing of scaling relations for late crater excavation from the planetary surface record. Other aspects of this study are discussed. |
