“…Altogether 2.5 kg of coarse octahedrite of class IAB (Spencer 1938;Bronsten 1962;Aaloe 1968) pieces have (officially) been collected at Kaali; most are stored in the meteoritical collection of the Institute of Geology, Tallinn Technical University. In addition to iron, the material contains 7.25 wt% of Ni, but is also rich in rare elements like Ir, Ga, Ge, Re, Pt, and Au (Yavnel 1976;Kracher et al 1980). Mineralogical studies (Yudin 1968) of fragments from the Kaali crater field revealed typical iron meteorite minerals like kamacite (mean abundance = 96.8 vol%;), taenite (1.8 vol%), and schreibersite (1.7 vol%) (Yudin and Smyshlyayev 1963).…”

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.
