Claude Herzberg coauthored a reconstruction of ancient mantle melting from dated basalt compositions. Calculating primary magmas links petrology with mantle potential temperature and the thickness of crust produced by melting.[ref]
Thermal history of the Earth and its petrological expression by Claude Herzberg and others. Abstract and Methods: primary liquids and ambient-mantle temperatures
Distinguishing ordinary mantle melts from unusually hot komatiites is essential before using the rock record as a global thermometer.
