Igneous petrology most common application of stratigraphic dating on volcanic rocks. In petrology the mineral clinopyroxene is used for temperature and pressure calculations of the magma that produced igneous rock containing this mineral. Clinopyroxene thermobarometry is one of several geothermobarometers. Two things make this method especially useful: first, clinopyroxene is a common phenocryst in igneous rocks easy to identify; and secondly, the crystallization of the jadeite component of clinopyroxene implies a growth in molar volume being thus a good indicator of pressure. Most contemporary ground breaking in igneous petrology has been published in prestigious American and British scientific journals of worldwide circulation
