                                    Mn-Cr data are reported for chondrules from the Bishunpur and Chainpur
LL chondrites. It is shown that variations in Mn/Cr for these chondrules
were established during condensation of solids from the solar nebula;
the whole-chondrule isochrons should give an upper limit to the time of
chondrule formation and an estimate of when the chondrule precursors
were condensing from the gaseous solar nebula.
