fracture
The property of minerals that break with jagged surfaces is called "fracture." This type of breakage occurs when a mineral does not break along cleavage planes but instead produces irregular, rough surfaces. Fracture can be categorized as conchoidal (smooth and curved) or uneven (jagged and rough).
a fracture
Minerals that break with an uneven rough or jagged surface are classified as having a fracture. Some examples of minerals with this type of fracture include quartz, fluorite, and obsidian. These minerals break in a way that does not exhibit any distinct cleavage planes.
a property called conchoidal fracture, which is characterized by smooth, curved breakage surfaces similar to those seen on broken glass. This type of fracture is common in minerals like quartz, obsidian, and flint.
Cleavage is the property that examines a mineral's ability to break into even pieces along specific planes or directions. Minerals with good cleavage will break cleanly and smoothly along these planes, while minerals with poor cleavage will break in irregular or jagged shapes. Cleavage is determined by the internal atomic structure of a mineral.
When a mineral breaks into jagged pieces, it is called a "fracture." This occurs when the mineral does not break along cleavage planes, resulting in rough and irregular surfaces. Fracture types include conchoidal (shell-like), fibrous, splintery, and uneven.
Sediment.
Sediment.
Minerals like quartz that break into pieces with jagged edges are typically classified as having a conchoidal fracture. This type of fracture produces smooth, curved surfaces with sharp edges resembling the shape of a clam shell, hence the name "conchoidal." Other minerals with conchoidal fracture include obsidian and flint.
Sedimentation
When minerals break along certain planes, it is known as cleavage. Typically, the pieces will be the same form and be bounded by smooth, flat surfaces. Cleavage is determined by the number of cleavage directions and the angle(s) between them.If the mineral breaks in an irregular, jagged or splintered edge, it is said to have a fracture.
