In this study, we made use of micromorphological characterization in order to understand the processes of filling of a paleovalley head (paleo-valley floor of zero order) at the Pinhão Surface / Guarapuava. Based on macroscopic characterization, four sedimentary sequences that fill the paleovalley head were recognized: buried paleosol with cumulative top, lower colluvial-alluvial sequence (co-alluvial), intermediate colluvial sequence and superior colluvial sequence. We collected undisturbed samples for the micro-morphological analysis, which counted on nomenclature and descriptive criteria by Stoops. As a result, we identified the constituents related distribution (CRD) of the integrated type (enauli-porphoric and porphyrous-enaulic), points to different streams in the sedimentation process. Enaulic CRD presents granular aggregates and, in micro-aggregates, it indicates sheet wash. Phorphoric CRD, in its turn, exhibits a massive microstructure, pointing to dense stream, possibly mud streams. The materials that compose the colluvial-alluvial sequence (co-alluvial), intermediate colluvial sequence and the upper buried paleosol come from the process of sheet wash. From the superior colluvial sequence, the process of mud stream was predominant, and it led to the filling of the paleovalley head with the superior colluvial sequence.References
