Why do you get faster connection at work than home? The rheology of polymineralic rocks is complex as the various minerals within the rock have different deformational behaviors (e.g. These mineral distributions or arrays provide the maximum work per unit stress and the maximum decrease in the mechanical potential energy for the system and are regarded as the equilibrium arrays. . Durham University, Butcher AR, Merkle RK (1987) Postcumulus modification of magnetite grains in the upper zone of the Bushveld Complex, South Africa. This is the most important difference between most igneous monomineralic rocks (which need to be more than 90% pure to earn its name) and sedimentary and metamorphic rocks. Dunite is an igneous rock made of olivine (over 90%). If a mineral does not display cleavage, it is said to have fracture, which means it breaks unevenly.A mineral that shows uneven, irregular .

Many quartzite samples are composed of almost pure interlocking mass of fused quartz grains just as the sample above. Together they form a unique fingerprint. Most rocks are polymineralic (i.e., contain more than one mineral); however, a few are monomineralic, eg., limestone and marble. The vein mineral assemblages are quartz + albite + K-feldspar + chlorite calcite (Type I, II) and quartz + albite + calcite (Type III). But some of them are reasonably pure to be called monomineralic. PubMedGoogle Scholar.
