WebCleavage of Minerals. the ability of most minerals to break in certain directions yielding plane surfaces. Cleavage is a property related to characteristics of the mineral’s crystal … WebGypsum occurs in two main varieties as white earthy masses or as clear crystals. In crystal form, its softness and single perfect cleavage with two less well-developed cleavage directions usually serve to distinguish gypsum from other similar-looking minerals. Anhydrite: When gypsum loses its water component, it forms the mineral anhydrite …

WebThe cleavage properties of a mineral are described in terms of the number of cleavages and, if more than one cleavage, the angles between the cleavages. The number of cleavages is the number or directions in which the mineral cleaves. A mineral may exhibit 100 cleavage surfaces parallel to each other. Those represent a single cleavage … WebProperties of Minerals Different minerals are often defined by the set of properties described below: Luster - Luster describes how well a mineral reflects light. Examples of luster include glassy, metallic, brilliant, and dull. ... Cleavage - Cleavage describes how a mineral breaks up into pieces. Some minerals break up into small cubes while ...
