Mineral Nucleation and Growth Flashcards
Unit cell
the smallest stable form of a crystal structure, gets repeated to generate the entire crystal

requirements for mineral creation
the proper components mst be in the solution, and the environmental condistions must encourage precipitation

Homogeneous nucleation
A lucky nucles forms and starts growing by adding more components onto it’s edge. As it grows it’s charge becomes more stable

Homogeneous nucleation
Law of Bravis
the dominant crystal faces are those alligned to the unit cell, they have more places to attach to and will most likely outgrow other faces

Screw Deformation
in order to maximize stability as new unit cells are aded, the crystal grows in a spiral, or parking garage shape.

Heterogeneous nucleation
one mineral forms a crust on another existing mineral crystal with a similar composition.

Mineral Zonation
Minerals form rings as they grow, due to variations in crysatl composition, all kinds of info can be gleaned from this behavior
