Abstract
Experimental studies of lamproites are useful in determining low-pressure crystallization sequences and inferring the mineralogy of the source regions of these magmas. In such studies the composition of the rock used as a starting material must be as close as possible to that of an initial partial melt whose composition has not been modified by differentiation, assimilation, or hybridization. The compositions of phlogopite lamproites may come close to meeting this criterion, but it is unlikely that xenocryst-bearing olivine/madupitic lamproites represent unmodified primary partial melts (see Chapter 7).
