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:
“As the shade went up
And the ambulance came crashing through the dust
Of the new day, the moon and the sun and the stars,
And the iceberg slowly sank
In the volcano and the sea ran far away
Yellow over the hot sand, green as the green trees.”
—John Ashbery (b. 1927)
