Marble is a rock. This rock is created due to metamorphosis of limestone. If the marble rock does happen to have cleavage, the cleavage refers to fractures within the marble rock itself.
Magnetite has fracture not cleavage. ChaCha on!
Rhyolite is a felsic volcanic rock.
Conglomerate does not exhibit cleavage--it fractures.
The mineral cleavage is made up of many other particles to form a rock when the rock cleavage is just a rock.
If igneous, it is called a porphyry.

Cobalt has perfect cleavage in all directions.
I dont think so because a rock can not have cleavage, but a mineral can
Because bauxite is a rock, a mixture of minerals, it has no cleavage of its own.
