Gloria Romero's Bill[edit]

I reckon that there should probably be a separate section on Serpentine as the state rock, if its included. It shouldn't be in the lede as it's just a news item at the moment and is hardly one of the most important aspects of this rock type. Mikenorton (talk) 21:33, 14 July 2010 (UTC)

Serpentine in an asteroid?[edit]

There's some speculation http://www.newscientist.com/article/mg20727794.100-solved-mystery-of-the-meteorshedding-asteroid.html that the asteroid Phaethon may contain Serpentine, which would explain why it is the source of the Geminid meteors. Mcswell (talk) 02:20, 24 September 2010 (UTC)

Alkaline[edit]

Is someone able to contribute some information explaining the alkalinity of the reaction products? As distinct from the acidity of volcanic hot vents, this is supposed to be of significance in abiogenesis conjectures. [1] Cesiumfrog (talk) 02:44, 9 August 2012 (UTC)

According to this, the reaction that gives rise to the high alkalinity is the breakdown of calcium-bearing clinopyroxenes, because there is no stable Ca-bearing phase under those conditions, leaving a fluid rich in OH-, with pH>10. Mikenorton (talk) 13:57, 9 August 2012 (UTC)

Why's it called serpentinite?[edit]

Is it just the colour...? — Preceding unsigned comment added by 82.0.16.12 (talk) 01:28, 6 April 2013 (UTC)
