WebSpecific gravity is the ratio between the mass (weight) of a mineral and the mass (weight) of an equal volume of water. A mineral's specific gravity (SG) can be determined by dividing its weight in air by the weight of an … WebCleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism. The degree of deformation and …

Did you know?
WebCleavage - Cleavage describes how a mineral breaks up into pieces. Some minerals break up into small cubes while others may break up into thin sheets. Specific Gravity (SG) - The specific gravity measures the density of the mineral. It is measured in comparison to water where water has a specific gravity of 1. http://www.geo.utexas.edu/courses/303/303_Lab/MineralOverhead.pdf
Cleavage, in mineralogy and materials science, is the tendency of crystalline materials to split along definite crystallographic structural planes. These planes of relative weakness are a result of the regular locations of atoms and ions in the crystal, which create smooth repeating surfaces that are visible both in the microscope and to the naked eye. If bonds in certain directions are weaker tha… WebBoth these properties represent the reaction of a mineral to an external force. Cleavage is breakage along planar surfaces, which are parallel to possible external faces on the crystal. It results from the tendency of …
WebCleavages are described in terms of their quality - how smoothly the mineral breaks - and their difficulty - how easy, or how hard, it is to produce the cleavage. The quality of cleavages are perfect, imperfect, distinct, good, fair, and poor . The difficulty is described as easy , hard, and difficult to produce.
