Question:
Which of the following group of minerals shows highest number of polymorphs?
Which of the following group of minerals shows highest number of polymorphs?
Show Hint
Mica minerals commonly show many structural variants because of different layer stacking arrangements.

- Mica
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Polymorphism means the same chemical composition occurring in more than one crystal structure. In sheet silicates, different stacking arrangements may produce many structural variants.
Step 1: Understand mica group.
Mica minerals are sheet silicates. Their layered structure allows different stacking arrangements.
Step 2: Polymorphs/polytypes in mica.
Because mica layers can stack in several ways, mica commonly shows many polymorphic or polytypic forms. \[ \text{Mica} \Rightarrow \text{large number of polymorphs/polytypes} \]
Step 3: Final answer.
Among the given mineral groups, mica shows the highest number of polymorphs. \[ \therefore \text{Correct Answer is (D)} \]
