A perfect cleavage produces smooth, lustrous surfaces with great ease. Other degrees include distinct, imperfect, and difficult. See also fracture.

The hardness of Schist is 3.5-4 whereas its compressive strength is Not Available. Streak is the color of rock when it is crushed or powdered. The streak of Schist is white whereas its fracture is conchoidal. Luster of Schist is the interaction of light with the surface of Schist. Luster of Schist is shiny. Schist cleavage is slaty.do garnet have cleavage or fracture - .does garnet have the property of cleavage or fracture Cleavage is what we see when a mineral breaks along a specific plane or planes, while fracture is an irregular break. Some minerals tend to cleave along planes at various fixed orientations, some do not cleave at all (they only fracture).Metamorphic Rock Identification Photos Flashcards .Luster: Vitreous to resinous Hardness: 6.5-7.5 Cleavage or Fracture: Uneven Color: Red-brown Streak:None Mineral Name: Garnet

Mineral Fracture There are several terms to describe the various mineral fractures: – Conchoidal - Fracture resembling a semicircular shell, with a smooth, curved surface.University of Minnesota's Mineral Pages: GypsumThe other two cleavage directions are not as pronounced, so broken gypsum crystals tend to form rhomb-shaped fragments, rather than cubes. Calcite: Calcite crystals can be distinguished from clear gypsum crystals by both their cleavage and the ease with .University of Minnesota's Mineral Pages: GypsumCalcite crystals can be distinguished from clear gypsum crystals by both their cleavage and the ease with which they react with dilute acid to effervesce or bubble. Calcite has three perfect cleavages that form rhombic fragments, while gypsum only has one perfect cleavage and two less distinct cleavage directions so that, when broken, it tends to form less well-developed rhombs than calcite does.Cleavage and Fracture Flashcards | QuizletCleavage and fracture differ in that cleavage is the break of a crystal face where a new face (resulting in a smooth plane) is formed, whereas fracture is the "chipping" shape of a mineral. All minerals exhibit a fracture. If a mineral with cleavage is chipped a certain way, it will fracture rather than cleave.Does garnet have a cleavage or fracture - AnswersDoes garnet have a cleavage or fracture? Top Answer.

When crystals break, they can either split leaving a clean, flat face called a cleavage plane, or fracture leaving a more rough, uneven surface. We can find out more about a crystal by looking at the way it breaks.
