Synonyms: Azul Barracuda, Baracuda, Barracuda, Blue Brasil, Blue Brasile, Brasilblue

Location: Blue Barracuda granite is quarried near Joao Neiva, Espirito Santo, Brazil.

Description: Blue Barracuda granite is a black-blue-brown cordieritefels with garnets. This stone internationally may be nominated as a granite however in the area of application of the European Standard we are awaiting clarification however, presumably, Cordierite.

A small sample of Blue Barracuda granite is not representative owing to a wide variation in colour and veining. 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, Blue Barracuda is frost resistant with a constant polish.

Mineral Composition: Brown feldspar, quartz and 10~30% steel-blue cordierite.

Physical Characteristics:
Compression tensile strength: 1993 kg/cm2
Tensile strength after freeze-thaw cycles: 1590 kg/cm2
Unitary modulus of bending tensile strength: 111 kg/cm2
Water imbibition coefficient: 0.002250
Mass by unit of volume: 2623 kg/m3

Cordierite: Also called dichroite or iolite, blue silicate mineral that occurs as crystals or grains in igneous rocks. It typically occurs in thermally altered clay-rich sediments surrounding igneous intrusions and in schists and paragneisses. Cordierite typically occurs in contact or regional metamorphism of argillaceous rocks. It is especially common in hornfels produced by contact metamorphism of pelitic rocks. Two common metamorphic mineral assemblages include sillimanite-cordierite-spinel and cordierite-spinel-plagioclase-orthopyroxene. Other associated minerals include garnet (cordierite-garnet-sillimanite gneisses) and anthophyllite. Cordierite also occurs in some granites, pegmatites and norites in gabbroic magmas.
