Round Things

Just because a rock contains circular or spherical features does not mean that the feature is chondrule and that the rock is a chondrite. Many terrestrial rocks contain circular features such as amygdules, rounded pebbles, and fossils. I’ve seen spherules in cavities that I suspect are eggs. Terrestrial rocks do not contain chondrules.

And, none of these rocks has a fusion crust.


This is the only meteorite of which I am aware that has large “round things” in it. 

NWA 7475, one of the several NWA 7034 pairs. At this time (October, 2020), this meteorite is the only brecciated meteorite from Mars.
