Location: Verde Ubatuba granite is quarried near Ubatuba, Sao Paolo, Brazil.

Description: Verde Ubatuba granite is a medium to coarse grained, olive-green granite (charnockite) of the Precambrian period with large quatities of quartz and some red garnets. This stone internationally may be nominated as a granite but in the area of application of the European Standard this stone must be nominated as a charnockite.

The veining and colour varies and a small sample of Verde Ubatuba granite may not be representative of the whole slab therefore swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use, Verde Ubatuba granite is frost free and polish constant.

There are many different quarries Of Verde Ubatuba granite, for large projects and matching ensure all the raw material comes from the same quarry since some granites, as shown in our sample, may have gold lines in them.

Charnockite: A hypersthene granite typical of Precambrian assemblages that contain migmatites. Charnockite is composed of orthoclase, oligoclase, quartz, and hypersthene; it also often includes the garnets almandine and pyrope, as well as biotite, magnetite, and other minerals. Two types of charnockites are distinguished: ferrohypersthene charnockite and garnet charnockite.
