In the present work the concepts of "stratum" are analyzed, " stratigraphic sequence " and stratigraphic laws in the frame of the theory of the archaeological stratification proposed by Edward Harris; across the conception estructuralista of Balzer, Moulines and Snned. The work: " Principles of Archaeological Stratigraphy " has marked the whole epoch of the urban archaeology in England characterized by beginning that are related to not historical attributes of the stratification or universally. Harris developed at the end of the seventies a graph in which the different stratigraphic units are represented, trying to expire with such requirements as the capacity of withdrawal of big quantities of archaeological information registered with reliability; the establishment of sequences archaeological stratigraphic that allow the check of all the stratigraphic relations including the incorporation of material artefactual and medioambitental. At the same time, one was trying to develop a technology of record that was expiring with the aims of normalization and standardization with independence of the type of excavation. Continuing To getting involved Alcaine (2010: 6) the principal controversies on Harris's work centre: " those who criticize the concept of objectivity understood with the double optics of the existence of a reality independent from the observer and, directly related to this one, the possibility of identifying and registering the evidence (the information) as appearing in the land); and secondly: " those who go more towards the conception of the warehouse. His process of formation and the relation of the stratigraphy with the geology. A little rejected incisively by Harris. " A reconstruction of the theory of Harris's stratification, from the conception estructuralist, will have to then understand an analysis of the potential models, the models, laws and specific concepts; partial models and conditions of bind so much as the intertheoretical links in terms metateóricos.
