Abstract:
The micromorphology is a ultramicroscopic and microscopy technique applicable for grounds and rocks studies in order to identify its primary components and their associations: skeleton, shapes, nodules and hollows. Based on micromorphology it is possible to recognize the mutual relations of those components in space and time. After soil obtaining, a thin section with a resin application is prepared to provoke the hardening allowing the cut. This study has the objective to contribute for the knowledge of the geologic characteristics that can indicate the behavior of an alteration profile of Cambissolo (INCEPTSOL). The analysis of the data allowed to infer about the systems of water percolation in several soil horizons. Horizon C is more outstandingly rich in sands when compared to the other horizons, but the hydraulic conductivity is very similar to the others horizons. In the images of thin laminas can be verified that the pore presence is not interconnected and, therefore, prevent the free circulation of water. It was possible to conclude that the micromorphology is an important tool for understanding the geologic-geotechnics characteristics and help in the interpretation of the geotecnic behavior.
