Obsidian exhibits a conchoidal fracture, which is characterized by smooth, curved surfaces resembling the shape of a shell. This type of fracture occurs due to the glassy nature of obsidian, allowing it to break in a way that creates sharp edges. The conchoidal fracture is a distinctive feature that makes obsidian useful for crafting tools and blades in prehistoric times.

Conchoidal is a type of what?
Conchoidal is a type of fracture that occurs in minerals or stones, characterized by smooth, curved surfaces that resemble the shape of a clamshell. This fracture pattern is commonly seen in materials like obsidian and quartz.
Does obsidian exhibits conchoidal fracture?
Yes, obsidian exhibits conchoidal fracture, which is a smooth, curved breakage pattern characterized by concentric ridges. This is due to its lack of internal crystal structure, which causes it to break in a unique, curved manner.
Conchoidal is an example of what?
Conchoidal refers to the smooth, shell-like fracture pattern seen in certain minerals and glasses, such as obsidian. It is a type of fracture that produces smooth, curved surfaces resembling the shape of a shell.
Do Glass exhibits conchoidal fracture?
Yes, glass exhibits conchoidal fracture, which is a type of breakage characterized by smooth, curved surfaces resembling the inside of a seashell. This type of fracture pattern is commonly seen in materials like glass, obsidian, and minerals with high silica content.
When a pyrite crystal is hit with a hammer it breaks into pieces with smoothly curved edges What is the new type of rock?
The type of rock formed from a pyrite crystal breaking into pieces with smoothly curved edges is conchoidal fracture, which is a type of fracture commonly seen in minerals like quartz and obsidian. This fracture pattern results in smooth, curved surfaces resembling the shape of a clamshell.
How much inches high is obsidian?
Obsidian is not identified, classified, or described by height. It is described by its texture, fracture, hardness, and chemical composition.
What is obsidian's cleavage?
Obsidian does not have cleavage because of the way it forms. Obsidian is essentially nature's form of glass and so it has no regular or patterned crystal structure. Without that crystal structure, there is no cleavage.
Minerals like quartz that break into pieces with jagged edges have?
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.
What is a type of obsidian?
One type of obsidian is snowflake obsidian, which is black with white mineral inclusions that resemble snowflakes.
What do minerals that break randomly exhibit?
Minerals that break randomly display a characteristic known as conchoidal fracture, where the mineral breaks in a shell-like, curved pattern. This type of fracture is commonly seen in minerals like quartz and obsidian.
Conchoidal describes a type of?
Conchoidal describes a type of fracture in minerals and rocks, characterized by smooth, curved surfaces resembling the interior of a seashell. It is commonly seen in minerals with strong atomic bonds, such as quartz, obsidian, and flint.
What is a curved fracture pattern is called?
A curved fracture pattern is called a conchoidal fracture. It is a type of fracture that results in smooth, curved surfaces resembling the interior of a seashell. This type of fracture is commonly seen in materials like glass and minerals such as quartz.
