Verde Lavras Granite Image

Description: Verde Lavras granite is a medium-grained, dark grey to olive-green 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. 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. Verde Lavras 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: Verde Lavras 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 possible that a sealant can be used on Verde Lavras granite 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: Verde Lavras granite is quarried at quarry RN 000171, Prata Joaquim Ferreira de Aguiar, 56-A, Santo Antonio do Amparo, Minas Gerais and also quarry RN 000180 & RN 000211, Sede, Fazenda Bela Vista, Ijaci, Minas Gerais, Brazil.

Synonyms: Green Lavras, Jade Green, Lauras, Lavras, Lavras Green, River Green, Verde Labras, Verde Lavaras, Verde Lavras, Verde Lavrus, Verdi Lavras.

Gneiss: A high grade metamorphic rock. Gneiss is medium to coarse-grained and may contain abundant quartz and feldspar, which some petrographers regard as essential components. The banding is usually due to the presence of differing proportions of minerals in the various bands; dark and light bands may alternate because of the separation of mafic (dark) and felsic (light) minerals. Banding can also be caused by differing grain sizes of the same minerals. The mineralogy of a particular gneiss is a result of the complex interaction of original rock composition, pressure and temperature of metamorphism, and the addition or loss of components.

Petrographic Composition: Average Plagioclase 33%, Quartz 30%, Microperthitic Microline 20%, Hornblende 10%, Biotite 5% Mafite 2%
