Description: G608 Granite is a coarse grained red-brown-white trondhjemite 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 Tonalite. During the polishing process a clear epoxy resin filler may be used to fill any micro fissures or tiny pitting however this does not affect the integrity of the stone, it merely provides an even smoother surface finish. G608 Granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.
Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.
Surface Finish: G608 Granite looks best with a gloss polished surface but is also available as honed, leather/satin, river-washed/antique, thermal/flamed, brushed and sandblast finish.
Sealing: Test with a small sample. It is most unlikely that a sealant can be used on G608 granite due to the grain formation, attempts at sealing it could actually create a residue film build-up.
Block Sizes: This is a quarry yielding selectable, grades of granite with blocks suitable for gangsaw size down to economical tile-sized blocks. For commercial projects it is important to ensure that blocks are selected from the same quarry face.
Rough blocks are usually exported by Break Bulk however intermodal containerisation is available at extra cost. Finished products are packed into sea-worthy wooden crates and loaded into containers.
Quarry Location: G608 Granite is quarried near Luodong, Nan'an, Quanzhou, Fujian province, China. There are probably several different quarries all producing slightly different shades and graining.
Synonyms: G3508, Mayflower Snow, Pink Spotted, Snow Plum Nanan
Trondhjemite: A light-coloured tonalite (leucotonalite) in which plagioclase is dominated by oligoclase. Trondhjemite is most common as part of Archean trondhjemite-tonalite-granodiorite (TTG) suite of intrusions and are usually high-grade metamorphic rocks. It is distinguished by a relatively high SiO2 content (expressed in the rock as abundant quartz) and a high Na/Ca ratio.
Tonalite: An igneous, plutonic (intrusive) rock, of felsic composition, with phaneritic texture. Feldspar is present as plagioclase (typically oligoclase or andesine) with 10% or less alkali feldspar. Quartz is present as more than 20% of the rock. Amphiboles and pyroxenes are common accessory minerals. In older references tonalite is sometimes used as a synonym for quartz diorite. However the current IUGS classification defines tonalite as having greater than 20% quartz, while quartz diorite varies its quartz content from 5 to 20%.
