Research interest

Dr. Larry M. Heaman specializes in the application of radiogenic isotope systems (U-Pb, Pb-Pb, Rb-Sr, Sm-Nd, Lu-Hf ) to a wide variety of geological problems related to crust/mantle evolution through time. A primary focus is the application of U-Pb geochronology to dating terrestrial and extraterrestrial materials including minerals, such as zircon, baddeleyite, monazite, titanite and perovskite, and fossils.  Current research projects include deciphering the origin of Large Igneous Provinces, the nature of the Archean/Proterozoic boundary, the isotopic architecture of the subcontinental mantle, the origin of kimberlites and related rocks, the precambrian crust/mantle evolution including the nature of Earth's earliest crust.
