Minerals (basics)

Minerals are the building blocks of rocks. Learn the scientific language of mineral identity and crystal structure.

Foundations

What makes a mineral

A mineral is defined by chemistry + structure, not just color.

Composition

Chemical formula (major elements) and substitutions (minor elements that swap into the lattice).


Crystal structure

Ordered atomic arrangement that controls cleavage, hardness, and optical behavior.


Habit

Common crystal shapes (prismatic, tabular, fibrous, massive) that help with identification.


Mineral groups

Silicates, carbonates, oxides, sulfides, sulfates, halides, phosphates, and native elements.
