Chert, a form of quartz, can form as beds or nodules in limestone or dolostone.
chert.
Very much so. It is a very widespread sedimentary rock.
Limestone for sure, dolomite mildly.
Most likely, it would be chert.
Sedimentary rock (limestone, slate, etc) forms when small particles sink onto the seabed, along with dead animals or plants, forming deep layers of mud. Over a very long time, the lay may be subjected to enough pressure to form sedimentary rock, encasing the fossils.
Fossils are nearly always found in some type of sedimentary rock. Limestone is a sedimentary rock which very commonly contains fossils, as is coal.
Metals are very good electricity conductors. Metalloids are half metals, half non- metals which can conduct electricity, but not as good as metals can. Limestone is a sedimentary rock composed largely of the minerals calcite and/or aragonite, which are different crystal forms of calcium carbonate (CaCO3). Therefore, limestone cannot conduct electricity. TheLostJammer
Limestone is composed of the skeletal remains of minute sea creatures. The layers are then subjected to compression and, over a very long time, hardened into a sedimentary rock.
