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
events.
