    16-12-2021 · Limestone may have been deposited by microorganisms in the Precambrian, prior to 540 million years ago, but inorganic processes were probably more important and likely took place in an ocean more highly oversaturated in calcium carbonate than the modern ocean. Why is limestone deposits a good place to look for fossils?

  • What makes limestone a good building material?

    Distal-disseminated silver-gold deposits are still another type of limestone related deposit. They contain silver and gold in stockworks of thin quartz and sulfide veins in limestone-rich sedimentary rock. They are not as common as the Carlin-type, but have still yielded millions of ounces of gold and silver.

  • Limestone - Sedimentary rocks

    Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium
