1. I BELIEVE that the metal in pallasites and other stony-iron bodies has a lower melt temperature than the largely silicate olivine grains.
2. An event that melts(ed) the metallic component of pallasites and mesosiderites might have little, if any effect on the other components.
3. A group of rapidly spinning metallic bodies might develop localized eddy currents which could melt or plasticize pockets of nickel-iron (induction heating). Say, if an impact broke up a largely iron asteroid, but was only sufficient to impart some angular velocity to the fragments, not drive them completely out of each others' influence.
4. Would the same rapid spinning be able to force plastic metals into cracks or joints between olivine crystals, thus forming a pallasite structure?
As I said, pure speculation (but fun!) Tracy Latimer
