Pełniejszy materiał źródłowy / excerpt

A chondrite (, CON-drite) is a stony (non-metallic) meteorite that has not been modified by either melting or differentiation of the parent body. They are formed when various types of dust and small grains in the early Solar System accreted to form primitive asteroids. Some such bodies that are captured in the planet's gravity well become the most common type of meteorite by arriving on a trajectory toward the planet's surface. Estimates for their contribution to the total meteorite population vary between 85.7% and 86.2%. Their study provides important clues for understanding the origin and age of the Solar System, the synthesis of organic compounds, and the origin of life and the presence of water on Earth. One of their characteristics is the presence of chondrules (from the Ancient Greek χόνδρος chondros, grain), which are round grains formed in space as molten or partially molten droplets of distinct minerals. Chondrules typically constitute between 20% and 80% of a chondrite by volume. Chondrites can be distinguished from iron meteorites by their low iron and nickel content. Non-metallic meteorites that lack chondrules are achondrites, which are believed to have formed more recently than chondrites. There are currently over 27,000 chondrites in the world's collections. The largest individual stone ever recovered, weighing 1770 kg, was part of the Jilin meteorite shower of…

The Wedel find in the context of the Morasko/Seeläsgen and other IAB irons: revisiting the largest iron meteorite shower in Europe. Although the most popular theory holds that the Morasko meteorite fall occurred about ~5000 BP, some research results indicate that it may have happened only 700–800 years ago. Chronicles from historical Poland and Germany report a meteorite shower and the destruction it caused. When, in 2024, a new iron meteorite from the IAB group was found in Wedel near Hamburg, Germany, it became necessary to verify whether it might belong to the same fall as Morasko and Seeläsgen. Unfortunately, the initial studies of this find were carried out using a method different fro…
