The discussions with regard to the use of the stratigraphy in archaeology have centred on achieving a systematizing that was allowing to unify standards and common procedures in the definition and classification of stratigraphic units. On the other hand, great part of this work has had points of contact with the geology in his beginnings and in the contemporary development of the own archaeology according to theoretical lines of thought. In the present work there are analyzed aspects linked with the emergence of the stratigraphy in archaeology, the identification and discussion concerning the stratigraphic units. Secondly, is commented which was the theoretical contribution that Edward Harris realized from his text " Elements of Archaeological Stratigraphy " and that critical was receiving on the part of the archaeological community.
