Green ubatuba (Port. verde ubatuba) is the commercial name of a Brazilian charnockite, although it often sold as a granite. It comes from the Ubatuba area of Brazil, where it forms part of the Neoproterozoic Ribeira Belt. As its name indicates, it is green in color, dark green and almost a black appearance when seen in low light. It contains large (10 cm) phenocrysts of alkali feldspar. It is widely used in home renovations and landscaping.
Famous quotes containing the word green:
“There was an old man lived out in the wood,
His trade was a-cutting of Broom, green Broom;
He had but one son without thrift, without good,
Who lay in his bed till ‘twas noon, bright noon.”
—Unknown. Broom, Green Broom (l. 1–4)
