Resumen:
Although large amounts of petrological and
geochemical data on chondrules exist, there is still no consensus,
neither on the different processes that were active during and after
chondrule formation, nor on the nature of the processes that
give rise to liquid droplets [e.g., 1]. However, most of the scientists
working on chondrules today believe that crystals in chondrules
are precipitation products of the liquid (e.g., melt) and that
mesostasis represents residual liquid of the bulk melt. Here we
compare the texture of three chondrules from the UOC Tieschitz
L/H3.6 (PTS, Tieschitz L 3441-3443, NHMV) with the chemical
composition of their clear glassy mesostasis (residual melt?) in
order to contribute to our knowledge of the chondrule forming
mechanism.
