Chiemite and Muschelkalk cobble are breccia-like interleaved. Saarland impact, cut face, centimeter scale.
The most recent find of chiemite in the Saarland impact region (Nalbach, Saarlouis craters) concerns a cobble in which a larger piece of chiemite is breccia-like interleaved with a cobble (probably Muschelkalk in predominantly sandy facies) (photos). This supports the idea that during the impact the chiemite was mainly formed from a carbon melt (vaporized and condensed carbon from the heavily shocked vegetation) and that when it hit the rock it created a vesicular texture in it (partially carbonate melt, decarbonization).
This find should at least make the self-appointed great impact experts on the Internet think about how the Muschelkalk limestone got into the coal cellar and intimately aggregated with the coke.
From the Saarland impact region: chiemite interleaved with Muschelkalk limestone/Muschelkalk sandstone (cut face in the entrance photo). Picture width 10 cm.
Chiemite remains on the blistered cobble surface.
