Abstract
Since 1986, interest in recovering meteorites in the planet's great deserts has spread to such an extent that today many teams of searchers spend entire days there, chasing rocks that have fallen from space. Although important specimens have occasionally been recovered, most of the pieces collected in the field are simple terrestrial rocks. In this work we carry out a study and propose the appropriate system for knowing how to search for meteorites and what to do when we find them. Systematizing field work will make new discoveries increase their value considerably when they are properly treated and classified.
