What Does Conchoidal Fracture Mean?
A conchoidal fracture refers to a haphazard mode of breakage of a material that does not adhere to any fixed or well-described physical planes of separation.
Brittle materials are more likely to exhibit conchoidal fracturing. Several such materials exist in nature, such as jasper, quartz, obsidian, flint and other fine-grained materials. Conchoidal fracture is commonly observed in such materials due to their lack of a crystalline structure or cleavage.
