| dc.description | The
geological knowledge about the stratigraphy of Roraima Supergroup is based on the last three
decades. Its evolution has begun along the Paleoproterozoic (Orosirian Period), culminating
with the largest continuous Pacaraima Sedimentary Block. At Brazilian portion the unit is
related to Roraima Supergroup, divided from the base (oldest) upward into Arai Formation,
Suapi Group (Uiramutã Formation at the base, Verde, Pauré, Nicarã and Quinô on top), Uailã
Formation and Matauí Formation. In Venezuela represents Roraima Group, divided into
Uairén, Cuquenán, Uaimapué and Matauí formations. Where the results are available, a
correlation is made between both successions. The presence of several basic sills in different
horizons constitutes an excellent stratigraphy marker. A Mesozoic dyke with strikes N-S and
NNE-SSW is present. It’s expanded the terminology “Roraima Supergroup” to Venezuela
portion, in attention to hierarchic order of its subdivision and type sections. | |
