Dolomite is not an ore itself; it is a mineral composed of calcium carbonate and magnesium carbonate. However, the main source of magnesium is magnesite, while the main source of calcium is limestone. Dolomite can be found in sedimentary rocks as a secondary mineral.
In what climate would a limestone monument weather most quickly?
The type of climate that a limestone will weather more quickly i think will be a hot and dry climate.
Why are the textures and weight different from limestone and marble?
The textures and weight of limestone and marble differ mainly due to their mineral composition and formation process. Limestone is primarily composed of calcite and aragonite, giving it a more uniform and softer appearance, while marble is formed from recrystallized limestone with added minerals, resulting in a denser and more varied texture. This difference in mineral content also contributes to variations in weight, with marble generally being heavier than limestone.
How can igneos rocks become sedimentary rocks?
Igneous rocks can become sedimentary rocks through the process of weathering and erosion, which breaks down the igneous rocks into small particles. These particles are then transported and deposited, forming layers of sediment. Over time, the pressure and compaction from the overlying layers can cement the sediment particles together, creating a sedimentary rock.
How is gold and limestone different and alike?
Gold and limestone are both naturally occurring materials, but they differ in composition and properties. Gold is a precious metal that has a higher value and is often used in jewelry and currency, while limestone is a sedimentary rock composed primarily of calcite and is commonly used in construction for buildings and roads. Both materials have been used by humans for various purposes throughout history.
Which two process lead directly to the formation of breccia and conglomerate?
Breccia forms through the consolidation of broken rock fragments due to hydraulic fracturing, such as during landslides or faulting. Conglomerate forms by the deposition and lithification of rounded gravel-sized particles in a high-energy environment like a river or coastal shoreline.
How much does crushed limestone cost a yard?
The cost of crushed limestone per yard can vary depending on the quality and quantity you purchase, as well as your location. On average, prices can range from $30 to $60 per yard. It's best to contact local suppliers for accurate pricing in your area.
What type of resource is limestone?
Limestone is a sedimentary rock that is primarily composed of the mineral calcite. It is a valuable resource used in construction, agriculture, and manufacturing industries for materials such as cement, concrete, and steel production.
What type of rock is the calcareous mudstone?
Calcareous mudstone is a type of sedimentary rock that is composed mainly of fine-grained mud particles and contains a significant amount of calcium carbonate (calcite). It forms in marine environments where there is abundant calcium carbonate deposition.
What is the depositional environment of conglomerate rock?
Conglomerate rocks can sometimes have spaces between the rocks and other times be filled in with a matrix cement, like concrete. A common place to find conglomerate is near a river. Rivers, because they move at different velocities, are able to transport and deposit rocks of all different sizes.
How is it possible that a sedimentary rocks change into marble?
It is possible for a sedimentary rock to become marble through the effects of environmental conditions such as pressure and temperature. They help to alter the structural and textural characteristics of the rock thereby changing it form and appearance. Limestone is a common sedimentary rock that is transformed in Marble which is a metamorphic rock. The process of changing a sedimentary rock into a metamorphic rock is called Metamorphism.
Is a sedimentary rock dull or shiny?
Sedimentary rocks are typically dull in appearance due to their fine-grained texture and lack of large crystals. Shiny rocks are more commonly associated with igneous or metamorphic rocks that have undergone recrystallization processes.
What are the limestone impurities?
Some common impurities found in limestone include clay, sand, iron oxides, and organic matter. These impurities can affect the color, texture, and overall quality of the limestone. Proper processing and purification of limestone can help remove these impurities and improve its suitability for various applications.
What substance can enter into gaps between the grains in limestone?
i dunno to eb honest. btw sorry for upsetting you as i dont know the question myself.but i just tryed this
What happens to the particles when limestone forms marble?
When limestone undergoes metamorphism to form marble, the particles within the limestone recrystallize and become more tightly packed together. The original minerals in the limestone may change, leading to the formation of new minerals such as calcite and dolomite. This process also typically results in a more uniform and stronger rock with a distinctive crystalline texture.
How fossils are formed in sedimentary rock?
There are multiple methods of fossilization, but fossils generally are formed by rapid burial of organisms or traces of organisms by sediments. The website of the New York State Geological Survey offers a useful introduction to the differing processes of fossil formation. Please see the related link for details.
Is a glacier a sedimentary rock?
No, a glacier is not a sedimentary rock. A glacier is a large mass of ice that moves under its own weight, while sedimentary rocks are formed through the layering and cementation of sediment over time.
What product is made out of sand ash and limestone?
Concrete is made out of sand, ash, and limestone. Sand provides the bulk of the material, ash or fly ash acts as a binder, and limestone is used as a filler to enhance the properties of the concrete.
Is there heat in the formation of sedimentary rocks?
Yes, heat is involved in the formation of some sedimentary rocks. This heat can come from nearby volcanic activity or deep within the Earth's crust, and can contribute to the process of lithification, which transforms loose sediment into solid rock. However, overall, heat is not as significant in sedimentary rock formation as it is in igneous and metamorphic rock formation.
Why does the white limestone have to come by water?
White limestone is formed from the accumulation of calcium carbonate from the remains of marine organisms like coral and shells. This accumulation often occurs in shallow seas and is deposited from the water onto the sea floor over time, eventually forming limestone rock.
What makes sedimentary rocks red?
Well, sediment is usually a variety of things mixed together, like soil. In soil, you can see many different things, that's because sediment can contain things such as, dirt itself, leaves, dead organisms-such as plants and remains of animals (like if an animal was killed by another, the dead remains would decompose into small pieces). So, if sedimentary rocks (which basically is compacted soil/dirt) are red, it's something that got mixed into the sediment.
What sequence of change in rock type occurs as shale is subjected to increasing heat and pressure?
Shale undergoes metamorphism and transforms into slate, then phyllite, followed by schist, and eventually gneiss as heat and pressure increase. This progression represents a sequence of increasing metamorphic grade from low (slate) to high (gneiss) with changes in mineral composition and texture.
What two processes lead directly to the formation of both breccia and conglomerate?
Both breccia and conglomerate form through the processes of sediment deposition and lithification. Sediment deposition involves the accumulation of broken rock fragments and particles. Lithification then occurs as the sediments are compacted and cemented together to form solid rock.
What are breccias and conglomerates examples of?
Breccias and conglomerates are examples of sedimentary rocks composed of angular fragments. Breccias contain coarse fragments while conglomerates contain rounded fragments. They are formed through processes like compaction and cementation of sediments.
Which of these sedimentary rocks is made of the largest particles?
Conglomerate is a sedimentary rock made of the largest particles, which are typically rounded pebbles and boulders.
