This page shows close-up photos of rocks generated or altered by the asteroid impact and other phenomena related to the cratering event.
Suevite, building material of Nördlingen's spire. Melt structures and vesicles in the dark fragments.
Small fragment of jurassic limestone embedded in suevite. Image about 4cm wide.
Small piece of granite within suevite, from the cristalline basement rock. Image about 4cm wide
Reddish weathering of a metamorphic inclusion in the suevite. Image about 4cm wide
Suevite (light colour, centre) and "Bunte Breckzie" (reddish, right) in the quarry of Aumühle.
Poppies apparently grow very well on suevite...; quarry of Aumühle.
Jurassic limestone, shattered by the impact (below) and darker "Bunte Breckzie"; quarry near Ronheim.
Variegated fragments of the "Bunte Breckzie"; quarry near Ronheim.
"Bunte Breckzie": details
Scratch marks on limestone, caused by sliding of ejected material; quarry near Ronheim.
Sometimes scratch marks intersect, showing variations of movemnt of the ejected material.
So called "shatter cone" in jurassic limestone; Meteorkratermuseum Steinheimer Becken.
So called "Ries Belemnites": these fossils were fractured by the impact event.
Ries belemnite in strongly fractured limestone; Meteorkratermuseum Steinheimer Becken.
Moldavite from southern Bohemia. length 4cm.
Same piece of moldavite, from the other side.
