dc.descriptionGeologic mapping carried out in the Mossâmedes-Sanclerlândia - Córrego do Ouro region , State of Goiás, lead to the separation of the following geologic units in the southwestern part of the Serra Dourada : The Basal Complex of Goiás occurs in the north of the area, comprising cataclastic muscovite-granite-gneiss and migmatitic biotite-gneiss. The Araxá Group appears south of the ridge, and includes cordierite-hornblende-gneiss, garnet-biotite-muscovite gneiss, amphibolite, garnet-muscovite-schist, calcitic muscovite-biotite-schist and minor quartzite, marble and amphibole-schist. The sequence was intruded by two gabbro-norite-ultramaphite bodies, which are possibly chronologically related to a layer of greenschist unconformably overlying the Basal Complex in the North. The Upper Precambrian Canastra Group is the youngest unit of the region. It rests unconformably over the Basal Complex and the greenschist, whereas towards the South it is separated through and inverse fault from the Araxá Group. The group is composed of tourmaline-chlorite-schist, muscovitic quartzite with numerous intraformational conglomerate lenses in the upper part , quartz-schist and phyllite.en-US
