...MATS E. ERIKSSON; ÅSA M. FRISK Abstract The post-impact Dalby Limestone (Kukruse; Upper Ordovician) of the Tvären crater, southeastern Sweden, has been analysed with regards to polychaetes, as represented by scolecodonts. A palaeoecological succession is observed in the Tvären-2 drill core sequence...

... Water resurge into newly excavated impact craters causes both erosion and conspicuous graded deposits in those cases where the water is deep enough to overrun the elevated crater rim. We compare published information on resurge deposits from mainly the Lockne, Tvären, and Chesapeake Bay...

... Abstract Robert Hooke in the 17th century was the first scientist to consider the possibility of meteorite impact cratering, when looking at the lunar craters. Gilbert in the late 19th century considered it again when studying ‘Coon Butte’ (now known as ‘Meteor Crater’), Arizona, but attributed...

... (Tvären Bay, Sweden) show similar depositional elements in the crater fill section ( Dypvik and Jansa, 2003 ). Similarities exist in the Bear Swamp crater ( Figure 7 ) where chaotic and brecciated zones are evident on the image logs nearly up to the top of the crater fill section. Boulder-sized clasts...

...-scale impact in a carbonate platform environment. The target rocks of the relatively small Lockne and Tvaren craters (<10 km) were Ordovician carbonates and shales, but detailed sea-level analysis of the postimpact sedimentary rocks has not been documented (Ormò et al. 2007). The Alamo impact...
