 A thin section is a laboratory preparation of a meteorite sample for use with a polarizing petrographic microscope. A thin sliver is cut from the meteorite, mounted on a glass slide and then ground to a thickness of only 0.03 mm (= 30 microns). When placed between two polarizing filters, the mineralogy is awash in color which makes it easier to determine the composition of the analysed meteorite, while in transmitted light, thin sections reveal mainly the texture and crystal shape of minerals.


Particularly fascinating are the unequilibrated type 3 chondrites.

Chondrites are the largest group of meteorites. They allow us to glimpse the very beginnings of our solar system. The largest structural components of most chondrites are the glass-bearing chondrules, and there are numerous theories for their origin. Here is one:
Chondrules were born in the disk of gas and dust surrounding the young Sun, the same disk that gave rise to the planets. Lightning zaps and shock waves briefly heated isolated regions of the disk, partially melting the dust. The resulting silicate and metal droplets cooled to form the tiny chondrules, which soon collided and stuck together with other minerals to form chondrites.
