ESTRATIGRAFIA DO GRUPO BAMBUÍ NA SERRA DO JAÍBA, NORTE DE MINAS GERAIS.

Abstract

STRATIGRAPHY OF THE BAMBUÍ GROUP IN SERRA DO JAÍBA RANGE, NORTHERN MINAS GERAIS STATE. Serra do Jaíba is a small mountain range sited on the right side of the Verde Granderiver (northern Minas Gerais state). The stratigraphy of this morfological feature is made up by siltstones,limestones and arkoses of the Bambuí Group (Neoproterozoic). The sedimentary succession of the Serra doJaíba shows upper stratigraphic levels in comparison with other neighboring ranges at the same elevation.The presence of strata with opposite dips on both sides of the range represents a possible synclinal structure.This synclinal could explain the special stratigraphic arrangement of the Serra do Jaíba.

Key words: Serra do Jaíba, Bambui Group, stratigraphy, synclinal
