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 ??

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)

Semi-protected edit request on 6 February 2014[edit]

hello! Good eve sir Sir i want to do some editing in the limestone usage section as i do not find it explicit. i beg you pardon if this causes disturbance to the site. Ritz.ptk (talk) 12:55, 6 February 2014 (UTC)

Not done: please be more specific about what needs to be changed. --Anon126 (talk - contribs) 16:32, 6 February 2014 (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)

Relative importance of uses[edit]

It seems a little odd that the section on 'uses' spends a lot of time on the largely historical use of limestone as a building material, but mentions its major modern uses, for cement manufacture and crushed aggregates, almost as a throwaway. Maybe some knowledgeable person could add a little table showing the main uses in percentages? (talk) 14:54, 3 April 2015 (UTC)

Natural limestone erosion in the wild, in lengths of time[edit]

If any geologists or chemists know the properties that allow water to erode limestone in nature, it would be helpful to add that information. Stone Forest is an area in Yunnan Province that has formed over time as a result of water eroding the rocks. Creationists believe that the Earth is 6,000 years old, so limestone erosion should be be explained, and then amended to the Stone Forest article.
