Fracture Collection

Some minerals (and rocks) do not demonstrate a parting or cleavage along specific planes, but they do have a consistency in how they break.

The resulting surfaces are described as conchoidal (obsidian), uneven (hornblende), etc.

The important types of fracture are demonstrated with this collection.

6 specimens approximately 1 1/2" x 1 1/2", number-coded.

FRACTURE is the manner of breaking and appearance of a mineral or rock when broken other than along cleavage or parting planes.

The following collection of common minerals and rocks illustrates the different types of fractures.
