An ejection model for SNC meteorites: An indication for recent volcanism on Mars
When compared to other achondrites, Shergotty-Nakhla-Chassigny (SNC) meteorites are viewed as anomalous objects. This conclusion is based mainly on their extremely young crystallization ages and their short cosmic ray exposure times. Further, SNC's noble gas and nitrogen components indicate a martian origin for these objects. If these meteorites are from Mars, then the most confounding question facing the planetary science community is how were they ejected from the planet's surface. The following is an investigation of that question.
