The SHRIMP (Sensitive High Resolution Ion Microprobe) enables the accurate determination of the uranium-lead age of the mineral zircon, and this has revolutionized the understanding of the isotopic age of formation of zircon-bearing igneous granitic rocks.

Down to depths of a few kilometres the strength of rocks would be expected to increase.Also, by extrapolating backward in time to a situation when there was no lead that had been produced by radiogenic processes, a figure of about 4.6 billion years is obtained for the minimum age of the Earth.This figure is of the same order as ages obtained for certain meteorites and lunar rocks.These discoveries had a long-lasting influence on crystallography because they led to the development of the X-ray powder diffractometer, which is now widely used to identify minerals and to ascertain their crystal structure.Advanced analytic chemical equipment has revolutionized the understanding of the composition of rocks and minerals.

Working at the Geophysical Laboratory of the Carnegie Institution of Washington, D. Experimental petrology, both at the low-temperature range explored by van ’t Hoff and in the high ranges of temperature investigated by Bowen, continues to provide laboratory evidence for interpreting the chemical history of sedimentary and igneous rocks.
