A mineralogical and morphologic characterization of some asbestiformes minerals of commonuse in the industry was made. Natural samples of chrysotile, lizardite and antigorite of theserpentine group; and actinolite, tremolite and anthophyllite of the amphiboles group were used.They were studied with optical microscope on with the immersion method, scanning electronmicroscopy - EDS and X-ray diffraction. The resolve of the morphology and size of fibers hasspecial interest by the implications that this has in the human health. These characteristicsdetermine the penetration of asbestos fibers in the respiratory routes, those that are accumulatedin the lungs, having been able to cause to cancer or asbestosis.
