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. WebJul 1, 2000 · The ease with which such separation can happen depends on the density contrast between the crystals and the liquid, the viscosity of the liquid, the size of the crystals and the dynamics of the magma chamber system.
