FORMATION OF SECONDARY EJECTA CRATERS AND
THEIR EFFECTS ON PLANETARY CHRONOLOGY
![]()
Purpose: Our team, expert on issues of impact
cratering and Mars chronology, is completing
data collection and numerical simulation
on the spatial and size distribution of secondary impact craters around
Martian crater named ‘’Gratteri’’ in order to
constrain (a) crater counting techniques used to measure Martian chronology,
and (b) launch conditions of Martian meteorites.
