U-Pb dating of calcite-aragonite layers in speleotherms from hominin sites in South Africa by MC-ICP-MS

, 2010
Speleothems are found in association with hominin fossil-bearing cave deposits in South Africa and can be used to provide valuable chronological constraints.

Hydrothermal Vesuvianite: A U-Pb Dating Mineral

Lithosphere
Abstract Since mineral deposits are the products of multiple hydrothermal pulses, in many circumstances, selecting a robust mineral to date the different mineralization events precisely is important. Vesuvianite, usually known as a rock-forming or accessory silicate mineral typically found in metasomatic and regional metamorphic ...

A relational database of global U–Pb ages

Geoscience Frontiers, 2018
Abstract Enhanced understanding of how sampling techniques affect estimates of the global U–Pb age-distribution have, in turn, constrained U–Pb database design. Recent studies indicate that each continent has a unique age-distribution, as determined by zircon ages dated by the U–Pb isotope method.
