“…Based on an iridium content in peat Rasmussen et al (2000) and Veski et al ( , 2002Veski et al ( , 2004 concluded that the Kaali impact took place much later, about 800-400 BC (2800-2400 BP). This conclusion is clearly wrong.…”

Pollen analyses and radiocarbon dates from the bottom sediments in the Kaali main crater suggested that the crater group is at least 4000-5000 years old. Investigations of silicate impact microspherules in surrounding mires (Raukas et al. 1995) put the age about 7500-7600 yr BP. Recently we found both silicate and iron microspherules from organic sediments below well-dated beach ridge in Reo site what supports the conclusions that the most realistic age of the Kaali craters is 7600±50 14 C BP (8335-8537 cal BP) and the meteorite fall was from SSE to NNW.Keywords: silicate and iron microspherules, meteorite fall, meteorite craters, radiocarbon and OSL dates.

“…At the bottom of the largest one, the main crater is a natural lake, subject to significant seasonal variations of water level. Its diameter varies seasonally from 30 to 60 m and its depth ranges from one to 6 m (Tiirmaa 1994;Veski et al 2001;Veski et al 2004). Minor craters are small depressions surrounded by a low rim.…”

Impact craters and the extraterrestrial matter in their surroundings: case of Morasko (Poland) and Kaali (Estonia)

Investigations have been carried out in the area of meteorite impact craters within the Quaternary deposits in Morasko and the Silurian bedrock in Kaali. Both surface destructions occurred during the fall of cosmic bodies that induced formation of magnetic fine-grained material. The presence of extraterrestrial spherules in Morasko and Kaali and their cosmic origin state prove such a composition and character of the surface. Moreover, the amount of magnetic fraction is increased in the sediments in the environs of craters in relation to their surroundings. However, impact of similar meteorites under similar environmental conditions can generate various morphological, mineralogical and natural effects. Common features of the described areas are the occurrence of collateral craters, their formation in sedimentary rocks and presence of high amounts of extraterrestrial spherules in their environs.

Abstract-Three structures (Neugrund, Ka¨rdla, and Kaali) of proven impact origin make Estonia the most cratered country in the world by area. In addition, several candidate impact structures exist, waiting for future studies to determine their origin. This article is an overview of these proven and possible impact structures, including some breccia layers. It summarizes the information and descriptions of the morphology; geological characteristics; and mineralogical, chemical, and geophysical data available in the literature. The overview was prepared to make information in many earlier publications in local journals (many of which had been published in Estonian or Russian) accessible to the international community. This review summarizes the facts and observations in a historical fashion, summarizing the current state of knowledge with some additional comments, and providing the references.
