What are Dendrites?
Dendrite is a Crystal Formation
In geology a dendrite is a crystal with a multi-branching tree-like form. So it's basically a crystal formation.
Dendritic inclusions are relatively common and can be seen in many rocks and minerals. Dendrites can also be seen as snowflake formations and frost patterns on glass windows during the cold winter months.
The word 'dendrite' comes from the Greek 'dendron' meaning 'tree'.
Dendritic inclusions in rocks and minerals can look very similar to organic matter. Where present, a stone can initially be mistaken for a fossil.
