Resumen

There are analyzed different sediments of the rivers Combeima and Coello in the department of Tolima that they rely on tributaries that they end in the same ones with the intention of realizing a detailed study of an area geographically determined across the software ArcGis (with which the most ideal points were identified by great precision and different criteria of selection to take the samples), and the design and adjustment of a table of hydrographic concentration automated with which the particles of the sediments were separated for density. The samples obtained with this one equipment were analyzed by means of diffraction of X-rays and electronic microscopy of sweep, obtaining that these rivers contains minerals as
