METEORITE ZIELONA GURA
This meteorite belongs to the class chondrite is a stony (non-metallic) meteorite, was found in Poland near the village of Zielona Gura in the east of the country.
A chondrite /ˈkɒndraɪt/ 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 (whether quickly, or after many orbits) arriving on a trajectory toward the Earth’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, the origin of life and the presence of water on Earth. One of their characteristics is the presence of chondrules, which are round grains formed by distinct minerals, that normally constitute between 20% and 80% of a chondrite by volume.
Chondrites can be differentiated from iron meteorites due to their low iron and nickel content. Other non-metallic meteorites, achondrites, which lack chondrules, were formed more recently.
According to the chemical analysis of this methotrexate, it is one of the oldest in our collection, its age is estimated at 5000-6000 years, to establish when it fell on our planet, unfortunately, is not possible.
