Alamo Impact Crater Documented
Introduction: The early Late Devonian, wet-target Alamo Event at southern Nevada resulted in one of the best-exposed and well-dated impact deposits ever documented, the Alamo Breccia [1]. Because post-impact geologic processes have modified, obscured [2, 3] and perhaps wiped away its original morphological and architectural relationships, the crater stratigraphy has remained uncertain. Thus, th...
متن کاملAutomated Crater Delineation
Introduction: Crater detection algorithms (CDA) have greatly evolved in the last decade and are detecting much smaller structures with higher performances [1-3] which is permitting their use in the construction and upgrade of crater catalogues, namely for Mars [4] and Phobos [5]. Although improvements are still required in the CDA, namely for detecting metric craters in diameter with the same h...
متن کاملMeteor Crater, Arizona
The location of Meteor Crater is shown on nearly all highway maps of Arizona. It lies 6 mi (9.7 km) south of 1-40 between Flagstaff and Winslow in northern Arizona; the turnoff from 1-40, 34 mi (55 km) east of Flagstaff, is well marked by signs along the highway. Access to the crater is by a paved road that leads directly to a visitor center and museum on the rim of the crater. Qualified scient...
متن کاملDegradation of Victoria crater, Mars
[1] The 750 m diameter and 75 m deep Victoria crater in Meridiani Planum, Mars, is a degraded primary impact structure retaining a 5 m raised rim consisting of 1–2 m of uplifted rocks overlain by 3 m of ejecta at the rim crest. The rim is 120–220 m wide and is surrounded by a dark annulus reaching an average of 590 m beyond the raised rim. Comparison between observed morphology and that expecte...
متن کاملSmall crater populations on Vesta
The NASA Dawn mission has extensively examined the surface of asteroid Vesta, the second most massive body in the main belt. The high quality of the gathered data provides us with a unique opportunity to determine the surface and internal properties of one of the most important and intriguing main belt asteroids (MBAs). In this paper, we focus on the size frequency distributions (SFDs) of sub-k...
