Quantifying Exhumation at the Giant Pulang Porphyry Cu-Au

U-Pb radioisotope dating is now the absolute dating method of first choice among geochronologists, especially using the mineral zircon. For example, in continental Australia it is that of late Proterozoic massive Pb sulfide ore. Another approach often employed in U-Pb dating of high common Pb phases involves projecting a straight line

In summary, the laser ablation technique, using a magnetic sector ICP‐MS, can be used for the U‐Pb dating of zircons with a wide range of ages and is a useful complement to the established TIMS and SHRIMP techniques. This technique is especially well suited to reconnaissance geochronologic and detrital zircon studies.
