(Sorry, last question of the night.)

Anyone know anything about "oriented" chondrules in a meteorite? I was looking at the scan of that
condrite that I had shown in the question about polishing (thanks to all who gave advise, by the
way) and noticed that, for objects in the matrix that are oblong, the long axises of a large
percentage of them seem to be aligned in a prefered direction rather than point in random
directions.

Here is the base image:

And one with arrows added to a few of the larger objects. Many other chondrules seem to tend to be
aligned in the same direction.
