Description: G682 Granite is a medium-grained, yellow to pink granite 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 most probably would be nominated as a Tonalite. A small sample of G682 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. 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. G682 Granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.
There are principally three selections of G682 Granite as shown here, left to right, light, medium and gold. This is a very popular granite however a small sample of G682 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.
Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.
Surface Finish: G682 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: G682 absorbs liquid readily therefore it is important that a sealant be used on this granite when used in areas of high humidity and water usage however excessive 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: G682 Granite is quarried near Shijing, Fujian province, China.There are many different quarries of G682 granite all producing different colour shades and graining from pale yellow to a darker yellow or with a touch of pink.

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%.
