Magnetite has fracture not cleavage. ChaCha on!
Magnetite has fracture. No cleavage. A rock cannot have both.
The difference between the iron in magnetite and hematite is the charge. Hematite has all 3+ iron ( the iron when make the mineral loses 3 electrons) and magnetite has some 2+ iron (it only loses 2 electrons).
Two directions of cleavage, at 90 degrees to each other.
There is no growth because during cleavage the cells skip the G1 and G2 stages of interphase (when cell growth usually occurs). Because of this, cytoplasm volume stays constant throughout cleavage, only there are more cells to comprise the same volume.
Law of the Infinitesimal Dose (The more diluted a remedy is, the more potent it is.)
Magnetite is used in many ways. Magnetite can be used as magnets, which can be used for more than just keeping paper on the fridge. It can be used to generate electricity, keep trains on the tracks, and guide your way in the wilderness.
Cleavage
Ruby has a conchoidal fracture with vitreous fracture luster. Read more on the link below
they both show how rocks break
Minerals break in the main two ways cleavage and fracture. Cleavage is breaking in flat planes but fracture is more uneven even unpredictable. The hardest mineral to break would be the diamond, which is placed at a ten on Moh's hardness scale.
That is referred to as fracturing.
Diamond stone, because of its lattice structure of carbon atoms, is identified as an 'octahedral; perfect and easy' cleavage (according to Wikipedia). Read more, below.
When minerals break, they can either have fracture of cleavage. Fracture is what you're looking for, and like you said, it's what happens when the mineral breaks and leaves uneven surfaces. A good example of a fractured mineral is quartz. Cleavage, on the other hand, occurs when minerals break along weak atomic bonding planes. Cleavage creates your flatter, more geometric surfaces. Look at mica. It creates what look like sheets of paper due to it's excellent cleavage.
what type of breakage is more common deavage or fracture
The difference between the iron in magnetite and hematite is the charge. Hematite has all 3+ iron ( the iron when make the mineral loses 3 electrons) and magnetite has some 2+ iron (it only loses 2 electrons).
cleavage
The equicohesive temperature is an antiquated term for the temperature at which the cohesion (the strength) of the grain boundaries in a crystal (usually a metal) becomes equal to that of the crystalline interior. In practice, it is the temperature at which a transition from an intergranular to transgranular (cleavage)-type fracture is observed. Over time, the concept of the equicohesive temperature has been replace be a more nuanced understanding of the various possible deformation mechanisms possible in polycrystals, with low-temperature, intergranular fracture and transgranular cleavage being only two such examples.
Its referred to as a compound fracture or open fracture. See the related link for more information.
