Hi
The rainbow colour looks like oil to me. Maybe someone has used oil or WD40 to
clean it. I sometimes encounter 'rainbow' tektites and the guys want extra
because of it - in reality it is due to oil contamination, probably from the
mining operations.

Hi Aubrey,
yes a striking effect, isn't it.
That the stones were manipulated, we can categorically rule out.
The material was from alone fresh enough, that nobody would get the idea to
manipulate it, the chatoyant effect of the crust is visible in some places,
but not over the whole crust, the

Thank you for posting your pictures. I find the small Holbrooks fascinating.

and may be oriented. However, it's small enough to require a

Mild oxidation of silicate glass (fusion crust in this case) can produce
a rainbow effect, too. I've seen this in basalts in the field. I think
it is from a sheen of iron oxides created as the iron and/or sulfide
weathers out.

Greetings List,
After collecting specimens from the Kentland Disturbance recently, I found
many pieces of quartz. Is there any way (with a 10X loupe) to determine
if this is shocked quartz from the meteorite impact? I also found
several pieces of what appears to be a melt of some kind. I
Great observation Marc. Iridescence is common on many pahoehoe lava flows on
the Big Island, and is quite remarkable to see.

I've seen this rainbow effect in the fusion crust of a few specimens in my
life including Murchison, Ash Creek, and Buzzard Coulee. Jim Strope has a
great example of Murchison with this coloration in the crust here:

That brings up a good question, then - is this iridescence the result of
weathering, or does it come from heating? Either could cause mild
oxidation. I had assumed that the iridescence I saw in basalts came
from weathering, but perhaps it was a consequence of heating. Basalt

Simply amazing specimens. I wonder, has fusion crust with this iridescent
appearance ever been examined by a lab or university?

Pure speculation but my guess is that the rainbow sheen comes from refraction
due to some fine layering of material on the surface. In the case of fresh
unweathered falls it is almost certainly a phenomenon related to the crust
formation itself but one could imagine weathering causing a similar

Hi List
so I ask my self what does irisation produce?
lamellas (feldspar (labradorite)),
spheres (opal),
oxidation (bismuth skeleton crystals)
any more?
Thanks

I've seen this rainbow or blueing effect take place when quenching red
hot metals in water or oil. So I'm wondering if rapid cooling may be the
reason for this effect. Maybe even cool air on a rapid decent?

I would have to agree that the heating and cooling process does cause an
reaction where the surface does turn blue/rainbow color due to oxidation on the
surface of meteorite on entry into the atmosphere. I think the two factors in
this case is heat/flame and the oxygen
