Question

Quizplus · Accepted Answer

Conchoidal fractures are a characteristic feature of minerals like quartz, which have a tetrahedral crystalline structure and are very hard and brittle. When these minerals break, they typically exhibit smooth, curved surfaces with concentric ridges that resemble the interior of a seashell, hence the term conchoidal (meaning shell-like). Muscovite, fluorite, and pyroxene are not typically associated with conchoidal fractures.
