Predict what's on your test 5 Must Know Facts For Your Next Test Stony-irons are classified into two main groups: pallasites and mesosiderites. Pallasites consist of olivine crystals embedded in a nickel-iron matrix. Mesosiderites are brecciated rocks containing roughly equal parts of silicate rock and metallic iron-nickel. Stony-irons are believed to originate from differentiated parent bodies, possibly from the boundary between the core and mantle. They provide crucial information about the processes that occurred in the early solar system, including planetary differentiation. Review Questions What are the two main groups of stony-irons? What type of minerals do pallasites primarily consist of? Why are stony-irons important for understanding the early solar system?
