The following mineral dating and isotopic signature methods are used in the laboratory: Rb-Sr, Sm-Nd, Lu-Hf, Re-Os, Pb-Pb and U-Th-Pb. Instrumentation comprises magnetic sector mass spectrometers, in which ionization is made by vacuum heating (TIMS) or by inductively coupled plasma (magnetic sector ICP-MS).

Along with the spectrometers, a complete sample preparation infrastructure is available at Geotop (saws, grinders, shaking table, etc.). Binocular microscopes, magnetic separators (Franz), heavy liquids, high-temperature ovens and class 100 laboratories (including 4 clean rooms dedicated to different purposes) allow recovering rock minerals, digesting them and purifying chemical elements of interest from the matrix.
