Mineralogy and Crystallography
1. Define Polymorphism
Polymorphism refers to the phenomenon where the same chemical substance can exhibit different physical and even chemical properties due to variations in formation conditions, such as pressure and temperature. These variations lead to different arrangements of atoms within the crystal structure.
2. Define Isomorphism
Isomorphism occurs when two or more chemical compounds adopt the same crystalline structure.
3. Define Pseudomorphs
Pseudomorphs are minerals where the internal structure does not correspond to the external crystal form, resulting in a "false form."
4. Define Solid Solution and Mixing
- Solid solution: A homogeneous solid with a variable composition.
- Mixing: A type of solid solution where
