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)].
Which is harder limestone or clay?
Limestone would be potentially harder until the clay is fired. The problem we have here is that "clay" is an ambiguous term. There is no homogenous or standard formula for clay. However, clays can generally be formed and baked to become set and hard. This is called firing. Fired clay tends to be quite hard, and depending on the formula, might be harder than limestone.
Is Jurassic limestone harder than carboniferous limestone?
Jurassic limestone is generally considered to be harder than Carboniferous limestone due to differences in their formation processes and mineral content. Jurassic limestone often contains more calcite and has undergone different geological processes that can increase its hardness. However, the specific hardness can vary depending on the local conditions and the exact composition of the limestone in question. Overall, while there are general trends, it's essential to evaluate individual samples for precise comparisons.
Why is marble harder than the rock form which it was formed?
Marble is harder than its parent rock, limestone, primarily due to the process of metamorphism. During metamorphism, limestone undergoes intense heat and pressure, causing the calcite crystals to recrystallize and grow, resulting in a denser and more durable structure. This recrystallization enhances the hardness of marble, making it significantly tougher than the original limestone from which it was formed.
Where do you find anhydrite?
Anhydrite is commonly found in sedimentary rock formations, particularly in evaporite deposits where it crystallizes from the evaporation of saline water. It often occurs in association with gypsum, halite, and other evaporitic minerals. Major deposits can be located in regions such as Michigan, Texas, and parts of Europe, particularly in areas with historical oceanic basins. Anhydrite can also be found in some hydrothermal veins and as a secondary mineral in limestone.
Is chalk harder than limestone?
No, limestone is harder than chalk. Limestone is a sedimentary rock composed mainly of calcite, whereas chalk is a soft, porous sedimentary rock composed mainly of calcium carbonate.
Is granite harder than limestone?
Yes

Contains oygen and carbon softer than fluorit but harder than gypsum?
limestone
What is a form of calcium carbonate softer than marble but harder than chalk?
Limestone is a form of calcium carbonate that is softer than marble but harder than chalk. It is commonly used in construction materials and can be found in different shades depending on the mineral impurities present.
Which is harder gabbro or limestone?
Gabbro is harder than limestone. Gabbro is a dense, coarse-grained rock formed from cooled magma, while limestone is a sedimentary rock primarily composed of calcite. Gabbro is more resistant to scratching and weathering compared to limestone.
Is dolomitic limestone same as agricultural limestone or horticultural hydrated limestone?
dolomitic limestone is different from agricultural or hydrated limestone the difference is in the MgO content and hardness Dolomitic Limestone is harder than both and its MgO content is higher. The CaO is lower in Dolomitic limestone and High in the later.

Which is harder sandstone shale or limestone?
"The two basic rocks found in the Mammoth Cave area are limestone and sandstone. Limestone is the "soft" rock (more water soluble) that is dissolved more easily by water. Sandstone and shale are the rocks that are on top of the cave. They are "harder" (less water soluble) and don't let the water soak into the cave." http://www.nps.gov/archive/maca/learnhome/cur_k3_cla.htm
What is a rock that is white and harder than chalk called?
A rock that is white and harder than chalk is likely to be marble. Marble is a metamorphic rock that is formed from limestone under high pressure and heat, making it harder and more durable than chalk, which is a soft sedimentary 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.
