WebFractional crystallization refers to processes which separate crystals from liquid. When this happens the liquid that remains is considered as a new magma. A number of processes can cause the crystals to be separated from a magma. Many minerals are denser than the liquid that they crystalize from.

WebIn general, mineral particles are small, having formed within confined areas such as lava flows or between grains of sediments. Large crystals found in geodes and other rocks are relatively rare. WebCurrent thoughts on the cause of color in minerals were summarized in an article in the American Mineralogist by Kurt Nassau (1978). He describes twelve separate causes, which can be placed in four main groups: 1) crystal field effects; 2) molecular orbital effects; 3) band gap theory; and 4) physical optics effects. More on each group later.

WebCleavage: In mineral terms, cleavage describes how a crystal breaks when subject to stress on a particular plane. If part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral has cleavage.
