Previous issue date: 2016-02-29 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / Esta Disserta??o de Mestrado compreende a an?lise estratigr?fica da Sequ?ncia Siluriana da Bacia do Parna?ba e est? vinculado ao Projeto de Pesquisa "Geologia e Sistemas Petrol?feros da Bacia Intracrat?nica do Parna?ba" financiado pela Chevron Brasil e UFRN/PPGG/FUNPEC. A Bacia do Parna?ba ? uma sin?clise paleozoica com ?rea de, aproximadamente, 600 mil km2 que situa-se no nordeste brasileiro e engloba parte dos estados do Maranh?o, Piau?, Tocantins, Par?, Cear? e Bahia.
A an?lise estratigr?fica efetuada neste estudo foi dividida em duas etapas denominadas an?lise 1D e an?lise 2D. Na an?lise 1D foram utilizados dados de po?os, tais como, perfis de raios gama e litol?gicos, os quais possibilitaram o reconhecimento das unidades gen?ticas e superf?cies cronoestratigr?ficas da estratigrafia de sequ?ncias. Por sua vez, a an?lise 2D baseou-se na interpreta??o s?smica, a qual, aliada ? an?lise 1D permitiu a demarca??o das superf?cies estratigr?ficas e o entendimento do comportamento bidimensional das unidades gen?ticas identificadas. Nesta etapa tamb?m foi confeccionada uma se??o estratigr?fica com dire??o aproximada NW-SE que possibilitou um melhor entendimento sobre a hist?ria de sedimenta??o da se??o estudada. / This review presents a stratigraphic analysis of the Silurian Sequence of Parna?ba Basin and is related to the ?Geology and Petroleum Systems of the Parna?ba Intracratonic Basin? Research Project, funded by Chevron Brasil and UFRN/PPGG/FUNPEC. The Parna?ba Basin is a paleozoic sineclisis which encompasses an area of approximately 600,000 km? and is located in the Northeastern Region of Brazil, distributed throughout the states of Maranh?o, Piau?, Tocantins, Par?, Cear? e Bahia. The stratigraphic analysis implemented in this study was divided into two stages, referred to 1D and 2D analysis. In the 1D analysis well log data were used, such as gama ray and lithologic profiles, which provided the recognition of the genetic units and chronostratigraphic surfaces of sequence stratigraphy. On the other hand, the 2D analysis was based on the seismic interpretation, which along with the 1D analysis allowed the delimitation of the stratigraphic surfaces and the understanding of the bidimensional behavior of the genetic units identified .At this stage, a stratigraphic section with NW-SE direction, approximately, was created as well, providing a better understanding about the sedimentary evolution of the studied section.
