Zeta Brown Granite Image

Description: Zeta Brown granite is a coarse-grained, brown monzonite. 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 monzonite. Ideal for both interior and exterior use, Zeta Brown granite is frost free and polish constant. The veining and colour varies considerably and a small sample of Zeta Brown 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. 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. Zeta Brown 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: Zeta Brown 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 Zeta Brown 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: Zeta Brown granite is quarried in Brazil.

Synonyms: Cafe Royal, Royal Coffee, Zeta Gold

Monzonite: An intermediate igneous intrusive rock composed of approximately equal amounts of sodic to intermediate plagioclase and orthoclase feldspars with minor amounts of hornblende, biotite and other minerals. Quartz a minor constituent or is absent; with greater than 10% quartz the rock is termed a quartz monzonite. If the rock has more orthoclase or potassium feldspar it grades into a syenite. With an increase of calcic plagioclase and mafic minerals the rock type becomes a diorite.

Quartz Monzonite: (Or adamellite) is an intrusive igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase. Quartz is present in significant amounts. Biotite and/or hornblende constitute the dark minerals. Quartz monzonite porphyry is often associated with copper mineralization in the porphyry copper ore deposits. Because of its coloring, it is often confused with granite, but whereas the mass of granite is 20% quartz, quartz monzonite is only 5-20% quartz.
