Dark Tan Granite Image

Description: Dark Tan Granite is a medium-grained, red-brown granite of the Precambrian period with both light and dark inclusions. 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. There is only one quarry of Dark Tan granite and the colour and veining does not vary much but there is the choice of a lighter variety. 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. Dark Tan 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: Dark Tan 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. We never use colour enhancers.

Sealing: Test with a small sample. It is possible that a sealant can be used on Dark Tan granite however excessive attempts at sealing it could actually create a residue film build-up.

Block Sizes: This is an exclusive, small-sized granite quarry yielding selectable, grades of granite with blocks suitable for gangsaw size down to economical tile-sized and monument blocks. Extraction commenced in the very early 1990s. 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: Dark Tan granite is from our own sheet bedrock quarry near Karimnagar, Andhra Pradesh, West and Eastghats, India. There is only one quarry of Dark Tan granite and the colour and veining does not vary much but there is the choice of a lighter variety.

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.
