SQUID2 software processes SHRIMP ion microprobe data. It derives ages for the U-Th-Pb system, radiogenic Pb isotope ratios and raw isotope ratios. It is jointly developed by Dr Ken Ludwig, Geoscience Australia and the SQUID2 Development Group.
SQUID2 is a Microsoft Excel add-In that processes PD files produced by SHRIMP ion microprobes into a variety of parameters, including raw isotope ratios, radiogenic Pb isotope ratios, ages for the U-Th-Pb system, and, via user-specified algorithms...
