- Crater of Steinheimer Becken. Diameter 3,8 km. Depth origenal crater ca 250 m. Diameter meteorite 150 m; no remnants are found. There is a central hill. Impact 15 miljon years ago.
- Impression of the Steinheim crater
- The layers are shifted some 20 degree at the crater border.
- These limestone layers are shifted but undamaged.
- 4 These lime stone layers are crumbled, relocated and physically changed.
- The crumbled limestone.
- A jet cone of limestone in the museum. Formed by the enormous pressure and temperature.
- 6 The central hill in the impact crater
- 7 From the central hill with view on the crater ridge.
- The village Steinheim at the bottom of the crater.
- The crater of the Ries is much larger and so more hidden in the landscape.
- The edge of the crater is on some distance of the tower of Nordlingen.
- Nördlinger Ries Crater: Diameter ca 24 km, Depth origenal crater is ca 1200 m. diameter meteorite is ca 1000 m, achondrite . Impact 15 miljon years ago.
- The limestone layers here at the Ried are turned some 45 degrees at the impact in a few seconds.
- This boulder of several thousands of tons was removed tens of kilometers outside the crater.
- The boulder.
- On this survace deep scratches arose by the rapid displacement of huge stones.
- The layer with the scratches and above it the breccia of the impact.
- The lime stone breccia.
- Under the breccia, a mixture of various stones, replaced in solid form in a few seconds. Above the suavite, the impact ‘tuff’ which felt down as ‘ash’ in a few hours.
- The red suavite
- Piece of Suavite
- Moon stone
- The suavite (impact tuff) of which the church was built is no more mined up now.
- Moldavite from Czechia. This tectite was in liquid form expelled at the impact and than replaced over some 400 km.
- Barringer Crater, Arizona. 50000 year BP, 1,2 km diameter, Meteorite ca 50m, type IAB.
