G684 black basalt

G684 black basalt (G684 black pearl) is a kind of black basalt quarried from Fuding city, Fujian province, southeast of China. This black basalt is extensively used for interior and exterior flooring tiles, paving slabs, countertops,worktops,urban furniture,landscaping elements for its unique and exquisite pattern.G684 black basalt has been widely adopted as the priority material for paving, facading, fireplace surrounds and kitchen worktops. We have been exporting G684 black basalt products to the US,European,Mid-East and the worldwide markets on regular shipment basis,please feel free to contac us for your requirement of black basalt at any time

What's basalt?
Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey.

The most common uses for this rock are as aggregate in highway construction, railroad ballast, and tile. Basalt is also a major component of asphalt.

On Earth, most basalt magmas have formed by decompression melting of the mantle. Basalt has also formed on Earth's Moon, Mars, Venus, and even on the asteroid Vesta. Source rocks for the partial melts probably include both peridotite and pyroxenite (e.g., Sobolev et al., 2007). The crustal portions of oceanic tectonic plates are composed predominantly of basalt, produced from upwelling mantle below ocean ridges

The term basalt is at times applied to shallow intrusive rocks with a composition typical of basalt, but rocks of this composition with a phaneritic (coarse) groundmass are generally referred to as dolerite (also called diabase) or gabbro.
