Verde Ubatuba Granite Image

Description: Verde Ubatuba granite is a medium to coarse grained, olive-green with large quantities of quartz and some red garnets charnockite 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 charnockite. 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 Ubatuba 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 Ubatuba 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 Ubatuba 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 Ubatuba granite is quarried near Ubatuba, Sao Paolo, Brazil.

Charnockite: A hypersthene granite typical of Precambrian assemblages that contain migmatites. Charnockite is composed of orthoclase, oligoclase, quartz, and hypersthene; it also often includes the garnets almandine and pyrope, as well as biotite, magnetite, and other minerals. Two types of charnockites are distinguished: ferrohypersthene charnockite and garnet charnockite. Charnockite was once thought to be igneous, but it is now known to be metamorphic since despite the high temperatures and pressures, the original protolith never actually melted.
