Volcanic shields on Mercury identified at last?

Wright, J.; Rothery, D. A.; Balme, M. R. and Conway, S. J. (2017). Volcanic shields on Mercury identified at last? In: UKPF 14th Annual Early Career Planetary Scientists' Meeting, 23 Jan 2017, University of Manchester.


Small (<50 km across) shield volcanoes are known on Earth, the Moon, Mars and Venus, but previous identifications of these features on Mercury have been reevaluated. Until now, only low-lying volcanic craters formed by putative explosive eruptions have been positively identified on Mercury. We have found two new candidate small shields at the edges of impact basins using orbital data from NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft. We introduce the better-evidenced candidate here.
