Halite, commonly known as rock salt, exhibits perfect cubic cleavage, meaning it breaks along smooth, flat surfaces that are perpendicular to each other, resulting in cubic shapes. This characteristic is due to its ionic bonding structure, which allows it to cleave easily along its planes of weakness. In contrast to cleavage, halite can also fracture, but this is less common and typically results in irregular or uneven surfaces.
frature
Conchoidal Fracture. Clevage is impossible in a pearl
Physical properties like clevage,fracture,color, ect.
Clevage-a flat cut. Fracture-a cut that hes bumps in it.
When minerals do not display cleavage, they are said to have a fracture. Fracture describes the way a mineral breaks when it does not have cleavage planes. This can result in irregular or random patterns of breakage.
There is no broken parts in quartz, so Quartz does not have cleavage.
No, a mineral cannot have both fracture and cleavage. Fracture refers to the way a mineral breaks when no cleavage is present, whereas cleavage describes the way a mineral breaks along its planes of weakness. Minerals either exhibit fracture or cleavage, but not both at the same time.
Mica exhibits cleavage, not fracture. Cleavage is a type of breakage along distinct planes due to weak bonds between atoms, resulting in smooth, flat surfaces. Conversely, fracture is an irregular breakage pattern across a mineral.
A pearl does not exhibit cleavage; instead, it tends to break in a way that is referred to as fracture. This is because pearls are composed of aragonite or calcite in a conchiolin matrix, which gives them an irregular internal structure. As a result, when subjected to stress, pearls typically fracture rather than split along specific planes like minerals that exhibit cleavage.
Diamonds typically cleave rather than fracture due to their crystalline structure. Cleavage in diamonds occurs along specific planes, allowing them to break cleanly and predictably. This property is a result of the strong covalent bonds between carbon atoms in their crystal lattice. In contrast, fracture refers to an irregular break, which is less common in diamonds due to their cleavage characteristics.
Limonite typically displays a fracture rather than cleavage. Its structure lacks distinct planes of weakness that would allow it to exhibit cleavage. Instead, limonite breaks irregularly along its surfaces due to its uneven internal structure.
oh yeah
