Additional data since the publication of Barrell's summary indicate that the average value of 8.2 percent for the porosity of shale may be low.Limestone is a sedimentary rock while marble is metamorphic. This means that the minerals in limestone are cemented together by natural processes, while marble is a result of metamorphism which recrystallizes the calcite and dolomite. The recrystallization process results in smaller grains and increases the overall strength of the marble.Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%).

Even though sand is made of rock fragments, its density is less because the porosity of sand lowers its bulk density (as shown below). (Note that the negative exponent in the units cubic ..., Slate is another common metamorphic rock that forms from shale. Limestone, a sedimentary rock, will change into the metamorphic rock marble if the right conditions are met. Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth., Sedimentary rocks form at or near the Earth's surface. Rocks made from particles of eroded sediment are called clastic sedimentary rocks, those made from the remains of living things are called biogenic sedimentary rocks, and those that form by minerals precipitating out of solution are called evaporites. 01 of 24 Alabaster, For example, when the sedimentary rock, limestone, gets put under a lot of heat and pressure, it can turn into marble, but metamorphic rocks still may not be done changing. Rocks can actually keep on changing forever. Igneous and metamorphic rocks can become sedimentary rocks if they're broken apart into sediments and go through lithification., Aug 25, 2023 · 2. Role in the Formation of Limestone and Marble: Limestone is a sedimentary rock primarily composed of calcite.
