Polujamki and Markovka fell within kilometers of each other and share all
macroscopic petrographic features except for two striking differences:
Polujamki, in photos I have found and in my specimen, seems to have, almost
without exception, a much higher frequency of >3mm pools of coalesced Fe-Ni, as
well as relatively more extensive shock veining/brecciation. Is this simply an
observation made from a specific paired stone that became available recently?
Can the amount of elemental metal dissemination in the original meteoroidal
body have been bimodally segregated due to localized shock, contributing to the
differences in trajectory of individual fragments of the stone as a result of
explosive aerial fragmentation?
