It shows a significant commitment in the Northeast since the 1970s by Franco-Brazilian missions and by other researchers eradicated it. The Archaeological Area of Sobradinho Northwest region of Bahia, boundary between the Middle and Lower Basin San Francisco shows up a rich area for archaeological research due to the large number of sites that have been identified in it. In the current phase of the study is limited in the north, with the border between Bahia and Piaui, with the east boundary of Bahia and Pernambuco and the thalweg Salitre River, to the south, with the coordinated UTMN 8700 and on the west with the UTMS 100. It is part of the polygon of droughts in the Northeast. It lies 70 km south of the National Park Serra da Capivara. In the area in question seeks to identify the boundaries of Subtradição Sobradinho characterized by the dominance of the theme that presents solid lines, diagonally upward and downward when horizontal, or from left to right and vice versa, when vertical. The graphic universe of Subtradição Sobradinho lies predominantly in brackets rocks of the Chapada Diamantina, Formação Tombador. By contiguity and the similarity of the features of this research unit where this subtradição was identified, formulates the hypothesis that their graphic sets belong to the same subtradição.
