Experimental petrology Experimental petrology Experimental petrology is the field of research concerned with experimentally determining the physical and chemical behaviour of rocks and their constituents. Because there is no way to directly observe or measure deep earth processes, geochemists rely on experimental petrology to establish quantitative values and relationships in order to construct models of the deep earth. Experimental petrology can range from creating artificial magmas to measure crystallization behavior to observing recrystallization of minerals at varying P/T (Pressure/Temperature) conditions. Although methodology varies from experiment to experiment, in general the procedure involves evaluating a synthetic rock or magma (created from a blend
