Mapeamento geológico integrado 1:50.000 da região da Serra da Jiboia (GO) - área 2

Abstract

This work begins through the processing and interpretation of image data, geophysical, geochemical, mineral resources and environmental data and following data collect of lithological, structural, environmental and mineral occurrence in field. The geological mapping in the Serra da Jiboia (GO) region intend to describe and interpretate the units Anicuns-Itaberaí Sequence, Gnaíssico-Migmatítico Complex and Santa Bárbara Body. The first fase of deformation is associated to the S1 foliation, to the intrafolial folds and quartz veins, the phase 2 is characterized for the shale which is well preserved in all area and associate with the assimetric isoclinal regional fold of the Serra da Jiboia. The third phase also receive emphasis by the extensive shear zone which occurs in the Santa Bárbara Body limits, this compressive deformational fase also occurs crossing folds. The fase 4 distinguishes for the crenulations and spaced cleavage. The potential economy of the area is diverse and with emphasis on clay and gravel occurrences.
