The base of ophiolitic sequences contains ultramafic rocks from oceanic lithospheric mantle. When found in continental terrain, these lithotypes show metamorphic processes that are registered in their mineralogy, chemical composition and textures. In the south of the São Francisco craton, between the cities of Itaguara and Crucilândia (Minas Gerais-Brazil), the Itaguara Sequence (SI) is located and it is composed of paleoproterozoic quartzites, schists, banded iron formations, ortho-amphibolites and metaultramafics. This study presents petrographic, geochemical and thermobarometric data from metaultramafic rocks of the Itaguara Sequence. Mineralogically they are composed of serpentine (antigorite), tremolite, talc, chlorite, olivine, spinel...
