Mineral Gallery the property of CLEAVAGE
Crystal cleavage is a smooth break producing what appears to be a flat crystal face. Here are a few rules about cleavage. First cleavage is reproducible, meaning that a crystal can be broken along the same parallel plane over and over again. All cleavage must parallel a possible crystal face.

Magnetite morphology and life on Mars | PNAS
Nanocrystals of magnetite (Fe3O4) in a meteorite from Mars provide the strongest, albeit controversial, evidence for the former presence of extraterrestrial life. The morphological and size resemblance of the crystals from meteorite ALH84001 to crystals formed by certain terrestrial bacteria has been used in support of the biological origin of the extraterrestrial minerals.

The magnetite crystals are variable in grain size (1–100 µm) and commonly form more or less continuous seams (up to 1 cm thick) that are broadly parallel with sedimentary bedding, although crosscutting magnetite veinlets are common. Magnetite crystals and aggregates tend to overprint and destroy earlier phases and textures.
