                         ABSTRACT: The article presents spectral curves of four Brazilian 
                         meteorites known as ordinary chondrites. A small bibliographic 
                         review about spectral signatures of meteorites is also presented 
                         with brief descriptions about the samples and their discoveries. 
                         The designs of the curves match very well with the signatures 
                         observed in the reviewed literature about chondrite meteorites of 
                         types L and H. At the end a tentative anlysis about parental 
                         bodies of the four rocky meteorites is done. This tentative is 
                         based on the spectral measurements obtained through telescopes and 
                         space probes over silicate asteroids of Type S located at the very 
                         center of the Belt. It was observed that S curves measured in the 
                         labs and by remote devices such as telescope and probes do not fit 
                         well with the curves of chondrites recovered on Earth. The cause 
                         maybe is the solar weathering that somehow changes the surface 
                         signatures of the S-asteroids. As a conclusion it is suggested 
                         that procedures described within this article could be extended to 
                         the others 71 known Brazilian metorites recovered up to 2017.",
