Precambrian limestone?[edit]

IF Limestone comes from hard-bodied marine organisms... AND IF hard-bodied marine organisms only evolved 550 Mya, during the Cambrian Explosion... THEN wouldn't that mean, that there is no Limestone older than 550 Myr?? No "Marine Snow" older than 550 Myr?? "Marine Snow" can accumulate to depths of 5-7 km in the deep ocean... how do all that Calcium Carbonates, and Silicates, affect Subduction Zones, and the upwelling magma along Volcanic Arcs there derived from ?? 66.235.26.150 (talk) 08:46, 2 October 2010 (UTC)

Limestone Value[edit]

So just how much is a quarry worth if it has 100 million tonnes of limestone reserves and a viable market to go with it? Is there a typical value used per ton once a quarry is permitted and operational? I have read $3.5 million per acre if an acre had 430,000 tonnes making the value about $8 a ton. Sales to be generated of about $18 million or $40 of sales per ton. Hammerstone2012 (talk) 22:19, 25 August 2012 (UTC)

Lacustrine limestone[edit]

There are quite a few articles that use the term lacustrine limestone. Some just point here, others to lacustrine (a disambiguation page) and some to lake, none of which seem like ideal solutions. Is there enough to say about this form of limestone that it could have its own section here, or article in its own right, so that clearer links could be made? --Derek Andrews (talk) 13:05, 14 February 2014 (UTC)
