Sedimentary laminations in the Isheyevo (CH/CBb) carbonaceous chondrite formed by gentle impact-plume sweep-up.

•Isheyevo is the first meteorite that shows prominent macroscopic sedimentary laminations.•It shows structural features indicative of gentle sweep-up from an impact plume.•Sweep-up occurred at velocities of between 30 and 200m/s.•The sediment was compacted under low temperatures, producing faults and load structures.•The metal grains show structures indicative of low-temperature deformation.•Isheyevo broadens our understanding of early Solar System accretion processes.
