Chemical Composition and Classification of the Caçapava Do Sul Meteorite / Composição Química E Classificação Do Meteorito De Caçapava Do Sul

Abstract

The amount of material present in the interplanetary space of the Solar System is still not completely known, as well as its size. Incidentally, they can be as small as grains of dust to bodies larger than 100 m in diameter. Meteoroids are a kind of these materials present in the interplanetary space are meteoroids. These are the bodies that penetrated the atmosphere reaching the Earth's surface, in this case, they are renaming like meteorite. They are similar ages to the origin of the Solar System, presenting geological characteristics similar to the known rocky planets. In fact, they can be an indirect means to extract information regarding the origin of the Solar System and the Earth. At the beginning of March 2017, a 26 cm wide and 27-kilo rock fallen in the early twentieth century, was confirmed as a meteorite. It receives the name of Caçapava do Sul Meteorite referring to the homonymous city. The meteorite was donated to the Universidade Federal do Pampa (UNIPAMPA), Campus Caçapava do Sul, Brazil, by the son of the person who finds the rock. This donation enabled the beginning of studies aimed at determining its chemical composition and its classification. This work is justified by the importance of understanding meteorites, as they keep records of the composition of the celestial bodies that make up the Solar System. Therefore, this work aims to classify the Caçapava do Sul Meteorite through geochemistry and determining its composition. And as a secondary, its classification according to the weather. Samples of the meteorite were sent to Prof. Dr.
