Anhydrite
Anhydrite is a special type of mineral that is made up of a specific combination of molecules. It's kind of like building with legos – if you put certain lego blocks together in a specific way, you'll end up with a certain object.
Now, anhydrite is made up of two things: sulfur and calcium. Just like how water is made up of two hydrogen atoms and one oxygen atom, anhydrite is made up of sulfur and calcium atoms.
When these atoms combine, they form a crystal structure that looks kind of like a bunch of boxes stacked on top of each other. This crystal structure is what makes anhydrite so unique.
Anhydrite is also special because it doesn't have any water inside of it. This is why it's called "anhydrous" – which means "without water". Other minerals, like gypsum, have water inside of them.
So, to sum up: anhydrite is a mineral made up of sulfur and calcium atoms, arranged in a special crystal structure that doesn't have any water inside of it.
