Most of them are found in shallow parts of the ocean between 30 degrees north latitude and 30 degrees south latitude. Limestone is forming in the Caribbean Sea Indian Ocean Persian Gulf Gulf of Mexico around Pacific Ocean islands and within the Indonesian archipelago.

In which rocks limestone is found?

sedimentary rock

Limestone is a sort of sedimentary rock. Approximately 10% of sedimentary rocks are limestones. The solubility of limestone in water and vulnerable acid answers ends in karst landscapes in which water erodes the limestone over lots to millions of years.

How deep can you find limestone?

4 000 to 7 000 meters

As a result there is a fairly sharp transition from water saturated with calcium carbonate to water unsaturated with calcium carbonate the lysocline which occurs at the calcite compensation depth of 4 000 to 7 000 meters (13 000 to 23 000 ft).

What is limestone formula?

Where is sandstone and limestone found?

Formation of Limestone and Sandstone

Limestone is found in beds and most limestone beds form in marine environments in which big deposits of organisms and carbonate precipitation build up over the years like an ocean or large lake.

Is limestone better than sandstone?

When it comes to texture limestone and sandstone are quite different. Limestone tends to be flatter and smoother with less ridges in its finish. Consequently this even finish means it’s ideal for driveways and also many indoor purposes too. … Sandstone on the other hand is slightly more uneven with a rippled texture.

Limestone is so versatile that this rock is used in more ways than any other. It is a low value material per ton perhaps only slightly more than standard aggregate rock but it is important in many products.

What happens when you burn limestone?
