SHRIMP has revolutionized geochronology allowing in situ U-Th-Pb analyses of U-bearing minerals in their petrological context. SHRIMP is often regarded as a zircon machine because of the productivity of the SHRIMP instruments in this area. However, SHRIMP is regularly used for stable isotope, isotopic anomaly, as well as trace element abundance measurements. This section deals with the development of SHRIMP, the geological ion microprobe.

SHRIMP allowed in situ dating of discrete zones in zircon. This
revealed for the first time the true complexities of the geochronology
of this mineral as well as its ability to record individual geological
