New Tunas Green Granite
Return to granite samples page.
Location: New Tunas Green granite is quarried in Brazil.
Description: New Tunas Green granite is a medium-grained, olive-green quartz syenite. 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 syenite.
The veining and colour varies and a small sample of New Tunas Green 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, New Tunas Green granite is frost free and polish constant.
Technical and Physical Characteristics:
Compression tensile strength: 2607 kg/cm2
Tensile strength after freeze-thaw cycles: 1973 kg/cm2
Unitary modulus of bending tensile strength: 134 kg/cm2
Water imbibition coefficient: 0.002300
Mass by unit of volume: 2751 kg/m3
Syenite: A coarse-grained intrusive igneous rock of the same general composition as granite but with the quartz either absent or present in relatively small amounts (<5%). The feldspar component of syenite is predominantly alkaline in character (usually orthoclase). Plagioclase feldspars may be present in small quantities, less than 10%.
