A novel sample pre-screening methodology for accurate in situ U-Pb dating of zircon crystals. [PDF]

Heliyon
Internal inhomogeneity of the zircon crystals makes it difficult to date succedent geological processes. To overcome this limitation, a four-step pre-examination method is suggested before LA-ICP-MS based in situ U-Pb age determination of zircon crystals:
