- Title
METEORITOS CONDRITOS: ROCHAS EXTRATERRESTRES PRIMITIVAS DO SISTEMA SOLAR.

- Abstract
Chondrites are considered the most primitive meteorites in the solar system and have this name because of the chondrules in their matrix. These materials have precious information about the beginning of the Solar System, as they did not experience fusion and igneous differentiation. Currently, the scientific community follows the classification that brings together meteorites in clans, groups and classes. This is important, because from the different properties found among the chondrites, it is possible to know the environment in which they were formed, it would be like the location of the "outcrop" and its "regional context" for geology. Thus, the main objective here is to develop a broad and synthesized review of chondrite meteorites. In general, chondrites are grouped into smaller clans and divided into Carbonaceous (C), Ordinary (CO), Enstatite (E), Rumirutitos (R) and Kakangaritos (K). It is important to mention that there are 3 processes that can alter its primordial characteristics of the chondrites, which are 1) The aqueous alteration, 2) The thermal metamorphism, 3) Impact or shock metamorphism, in addition to the terrestrial weathering itself. Finally, it is hoped that this article can contribute as a theoretical framework for undergraduate and graduate students, as there are very few articles and literature in Portuguese on meteorology and this work sought to provide a general overview of chondrite meteorites.
