Hello Bernd & List
I have seen some nice pieces of Tamdaght and i confirm the presence of a lot
of slickensides, confirming the high level of shock of this meteorite. That
could actually partially explain the fact that it was broken in many pieces
at 'landing', plus the fact that some of those broken individuals have met
the earth surface against the rocky Atlas Mountains.
All the best

Hello Steve and List,
My two pieces from Philippe & Léa support your statement that Tamdaght
has a very grayish matrix. I couldn't detect any chondrules, so H5 or H4-5
might be a good guess.
We know that there are many shattered, mostly small pieces and one of my
specimens seems to show "slickensides". If these slickensides are real, this
can be seen as evidence of the violent forces upon impact and may explain
the sheer number of broken pieces.
Best wishes,
Bernd
