Questions and Answers

What defines the internal structure of a mineral?

The minerals present in the same locality.

The minerals' colour and luster.

The mineral's origin and formation process.

The arrangement of atoms within the mineral. (correct)

How do polymorphism and pseudomorphism differ?

Polymorphism is about similar compositions with different structures; pseudomorphism is about one mineral taking the form of another. (correct)

Polymorphism refers to minerals with different compositions; pseudomorphism refers to altered minerals.

Polymorphism is the same as chemical composition; pseudomorphism refers to color changes.

Both refer to the same phenomenon of mineral changes over time.

The mineral's geological history.

Chemical stability over time.

Color and hardness. (correct)

The internal arrangement of particles.

Study Notes

Mineral Characteristics

Minerals have internal structures that are unique to each mineral
Minerals have a crystalline structure, which is visible under a microscope
Each mineral can have a unique chemical composition that is specific to that mineral
Minerals have physical properties such as color, hardness, and cleavage, all of which are unique
Some minerals have the same chemical compositions but different crystalline structures, which is called Polymorphism
Pseudomorphism is when a mineral takes on the characteristics of another mineral
Even minerals that have the same composition can show different habits (appearance)
Some minerals have specific structures, including single-chain or double-chain structures
Associated minerals are found in the same geological location
Fossils such as Fugichoria and Folibuccia can indicate the type of mineral present

Preservation of Fossils

Pleistocene fossils are preserved in the Pleistocene epoch
Examples of preserved Pleistocene fossil mammals include Rhiinoceroes and Plemmmoths
