The difference in color in the meteorite photo
above and below is
related to analog SLR photography above and digital in daylight
below.
The fragment below left photo was used for
whole sample XRD.
Above we see the part slice scanned on a color scanner and used for the
sample thin section production. At right we see the thin section and
visible are the sub-mm and micrometer level dust particles and grains.
Also viewable are some opaque oxide fragments.
We think we are on the verge of resolving how this
sample can appear as an igneous sample in the interior and upon
polishing and slicing, but appear as a layered microsediment at
the exterior of the sample. We believe the sample is composed of
abundant plagioclase and high calcium, magnesium, silicon and
transitional metal microdroplets produced in a stellar environment. The
subsequent adhering and bonding of the micro-particles in a very high
temperature and pressure environment produces what appears to be an
igneous sample. The weathering and subsequent break down of the
extremely tightly bound microdroplets in our terrestrial environment
creates a pattern consistent with larger ions and cations releasing
their energy and lining up in a manner to allow room for expansion and
breakdown. Consequently the sodium and potassium will take up the
larger ion space (white band) and magnesium, iron and calcium are
accommodated in the dark banded region.
