Basalt

Basalt is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. By definition, basalt is an aphanitic igneous rock with less than 20% quartz and less than 10% feldspathoid by volume, and where at least 65% of the feldspar is in the form of plagioclase.

(In comparison, granite has more than 20% quartz by volume.) Basalt is usually grey to black in colour, but rapidly weathers to brown or rust-red due to oxidation of its mafic (iron-rich) minerals into rust. It almost always has a fine-grained mineral texture due to the molten rock cooling too quickly for large mineral crystals to grow, although it can sometimes be porphyritic, containing the larger crystals formed prior to the extrusion that brought the lava to the surface, embedded in a finer-grained matrix.

Basalt with a vesicular or frothy texture is called scoria, and forms when dissolved gases are forced out of solution and form vesicles as the lava decompresses as it reaches the surface. On Earth, most basalt magmas have formed by decompression melting of the mantle. Basalt commonly erupts on Io, the third largest moon of Jupiter, and has also formed on Earth’s Moon, Mars, Venus, and the asteroid Vesta. Source rocks for the partial melts probably include both peridotite and pyroxenite.

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 diabase (also called dolerite) or gabbro.

Marble 2 Marvel are the company to use….. Everyone …  Avi the owner, Vanessa, the fitters and  Ian ‘the amazing templating guy’ are extremely professional, so friendly and,most importantly, are perfectionists. We are absolutely  thrilled with our  stunning work surfaces and would,without doubt,recommend this company. We have had so many ‘wow’ comments already!!

I must say how impressed I was with your installation team. I understand it was a very complex situation and it took 5 operatives to finally get the stone in place! However it now looks fantastic and the whole kitchen has exceeded our expectations.

Mr O’Neill, Stone Cross.

 

We are very satisfied with the service and very happy with the result, we obviously made a good choice and we would certainly recommend you.

Mr Oaten, Sedlescombe.

We wish to put on record our appreciation of the way we have been served right from the initial viewing of the worktop choices through to the efficient installation and finish of the worktop that now graces our new kitchen.

Mr and Mrs Kadwill, Eastbourne.

I was really happy with the excellent service provided by Marble 2 Marvel when I recently purchased new work tops. Every detail mattered to them and because of that I am a completely satisfied customer. Many thanks to their team.

Mrs Sandaver, Hastings.

I thought I should let you know we are absolutely delighted with our new Silestone worktop. It looks spectacular and finishes our new kitchen off perfectly…
