Is anhydrite harder than limestone?
Yes, anhydrite is generally harder than limestone. Anhydrite, which is composed primarily of calcium sulfate, typically has a hardness of around 3 to 3.5 on the Mohs scale, while limestone, primarily composed of calcium carbonate, has a hardness of about 3 to 4. However, the hardness can vary depending on the specific type of limestone and its mineral content. Overall, anhydrite is considered to be more resistant to abrasion compared to limestone.
What is the difference between Gypsum and Anhydrite?
Anhydrite is formed from dehydrated gypsum or to make it easier to understand when water is added to anhydrite it becomes gypsum as we can see from their chemical formulas [Anhydrite (CaSO4) and Gypsum (CaSO4-2H2O)].
What mineral group is anhydrite in?
Anhydrite is part of the sulfate mineral group. It is composed primarily of calcium sulfate (CaSO₄) and typically forms in sedimentary environments, often through the evaporation of seawater. Anhydrite is an important mineral in the formation of sedimentary rocks and can also transform into gypsum when hydrated.
What is the reaction when anhydrite is exposed to caustic soda?
When anhydrite (calcium sulfate mineral) is exposed to caustic soda (sodium hydroxide), a reaction may occur where the sodium from the caustic soda can replace some of the calcium in the anhydrite, forming sodium sulfate and calcium hydroxide. This reaction is often used in industrial processes for desulfurization or for the production of sodium sulfate.
Scientists use rock cycle to describe what process?
The rock cycle is how one type of rock can be changed into another type of rock.
What makes up anhydrite?
The chemical formula of Anhydrite is Calcium Sulfate. Sometimes the shell of anhydrite can be composed of strontium, depending where you find it.
What type of ejecta does el chichon have?
High-sulfur anhydrite-bearing magma and pyroclastic flows.

What are the uses of anhydrite?
it anhydrites.
What has the author Marcus I Goldman written?
Marcus I. Goldman has written: 'Deformation, metamorphism, and mineralization in gypsum-anhydrite cap rock, sulphur salt dome, Louisiana'
Name three common evaporite minerals?
Evaporates are found where there is water, such as soil. Three common evaporate minerals found in soil are Anhydrite, Mirabilite, and Thenardite.
What rocks are evaporites?
Evaporites are rocks that form by the precipitation of minerals from the evaporation of water. Common types of evaporites include rock salt (halite), gypsum, and anhydrite. These rocks typically form in arid environments where the rate of evaporation exceeds the rate of water inflow.
How might a geologist use acid in the field to identify carbonate rocks such as anhydrite and gypsum?
If you put cold dilute Hydrochloric acid on a carbonate rock the acid dissolves the rock and you get bubbles of carbon dioxide in the acid. This reaction will only happen with carbonate rocks.
Can you find gypsum during drilling?
no found because evaporit into anhydrite
