A U.S.-German research team led by Stony Brooks Lars Ehm and including other members of the Department of Geosciences in the College of Arts and Sciences at Stony Brook University has simulated meteorite impacts in the lab and tracked the resulting structural changes with X-rays. The two main subgroups are termed chondrites and achondrites, depending on the presence or absence of chondrules. Their chemistry is very primitive because they have had very few chemical interactions with other objects since their formation. stony meteorite (stone) A type of meteorite that consists of silicate minerals generally with some nickel-iron.
