      abstract = {Modern meteorite classification schemes assume that no  single planetary body could be source of both unmelted  (chondritic) and melted (achondritic) meteorites. This  dichotomy is a natural outcome of formation models assuming  that planetesimal accretion occurred nearly  instantaneously. However, it has recently been proposed  that the accretion of many planetesimals lasted over ≳1  million years (Ma). This could have resulted in partially  differentiated internal structures, with individual bodies  containing iron cores, achondritic silicate mantles, and  chondritic crusts. This proposal can be tested by searching  for a meteorite group containing evidence for these three  layers. We combine synchrotron paleomagnetic analyses with  thermal, impact, and collisional evolution models to show  that the parent body of the enigmatic IIE iron meteorites  was such a partially differentiated planetesimal. This  implies that some chondrites and achondrites simultaneously  coexisted on the same planetesimal, indicating that  accretion was protracted and that apparently  undifferentiated asteroids may contain melted interiors.},
