m10_aom_3_8.jpgTerraced Mercurian Crater with multiple central Peaks (HR)60 visiteThis crater (about 74 Km diameter) just North of the Caloris Planitia displays interior and central peaks rising up from a hilly floor. The continuous ejecta deposits and secondary crater field are well defined.

m10_aom_3_2.jpgTerraced Mercurian Craters (HR)60 visiteThis crater (about 98 km diameter) illustrates the narrow hummocky rim facies, radial ridges and surrounding extensive field of secondary craters.
The well-developed interior terraces and central peaks are typical for Mercurian Craters in this size range.
Note that the smaller craters in the foreground (25-Km diameter) also are terraced.

m10_aom_2_10.jpgThe "Antoniadi" Ridge of Mercury (HR)55 visiteAntoniadi Ridge, over 450 Km long, runs along the right side of this image. The ridge transects a large crater (80-Km in diameter) and in turn appears to be interrupted by an irregular rimless depression on the floor of the crater. This ridge also crosses smooth plains to the north and intercrater plains to the south of the large crater.
This image (FDS 27325) was acquired during the spacecraft's first encounter with Mercury.
