Mineralogy of Morasko meteorite and the structure of the craters

Abstract

This paper presents the results of geomorphological investigations of bowl-shaped hollows in "Rezerwat Meteoryt Morasko" - Morasko Meteorite Nature Reserve - of Poland and of mineralogical studies of recently found meteorites and micrometeorites. The meteorite shower fell between 5000 and 3500 BP, forming craters in the Morasko area. The age interval for this event was estimated by earlier palynological and 14 C studies. The Morasko meteorite is an iron type octahedrite (IAB group) which shows strong reheating effects. The investigated area is unique, because the material from space and the geomorphological effects of its fall can be identified there.
