Fossiliferous limestone, a common subtype, contains visible fossils embedded in its structure, providing valuable insight into past marine ecosystems. Another subtype, chalk, is formed from the microscopic remains of planktonic algae known as coccolithophores. 2.Apr 23, 2023 · Chemical composition and properties of limestone. Limestone is primarily composed of calcium carbonate (CaCO3) in the form of the mineral calcite. It may also contain other minerals such as dolomite (CaMg (CO3)2), clay minerals, and other impurities. The purity of limestone depends on the geological conditions under which it formed. The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. If the limestone is pure, a white marble is formed. Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble. Uses of marble: Building StoneFossil fuels are found in sedimentary rock, which is often located beneath a body or former body of water such as an ocean or swamp. Fossil fuels are nonrenewable resources that include oil, natural gas, and coal. They either have to be mined or drilled from Earth and cannot be easily replaced in a short amount of time.

Both marble and limestone may have the same composition, but marble typically has larger grains. Increased temperatures and/or pressures generate more intense grades of metamorphism.Study with Quizlet and memorize flashcards containing terms like How does fossil-containing limestone form?, What info does fossils provide, What do some of the features of sedimentary rocks indicate about ancient bodies of water and more.Any of my search term words; All of my search term words; Find results in...
