Synonyms:

Location: Verde Arara granite is quarried at quarry RN 000267, Estrada Garcias, Fazenda Garcias, Candeias, Minas Gerais, Brazil. It is believed quarrying operations stopped in 2001.

Description: Verde Arara granite is a fine to medium-grained, grey-green charnockitic gneiss of the Precambrian period. 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 gneiss.

A small sample of Verde Arara granite is usually representative not having a wide variation in colour and veining however 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 Arara granite is frost free and polish constant.

Mineral Composition: Olagioclase: 40%, Quartz: 23%, Microperthitic Microcline: 15%, Hornblende: 7%, Mafite: 7%, Hypersthene: 5%, Biotite: 5%

Gneiss: A common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. Gneissic rocks are usually medium to coarse-foliated and largely recrystallized but do not carry large quantities of micas, chlorite or other platy minerals. Gneisses that are metamorphosed igneous rocks or their equivalent are termed granite gneisses, diorite gneisses, etc.

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.
