Towards in situ U–Pb dating of dolomite [PDF]
Geochronology, 2021 Recent U–Pb dating by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has demonstrated that reasonable precision (3 %–10 %, 2σ) can be achieved for high-resolution dating of texturally distinct calcite phases.

Impact and Correction of Analytical Positioning on Accuracy of Zircon U-Pb Dating by SIMS [PDF]
Frontiers in Chemistry, 2020 Secondary ion mass spectrometry (SIMS) is one of the most important analytical tools for geochronology, especially for zircon U-Pb dating. Due to its advantages in spatial resolution and analytical precision, SIMS is the preferred option for multi-spot ...

Directly dating geologic events: U‐Pb dating of carbonates [PDF]
Reviews of Geophysics, 2009 Carbonates are ubiquitous, forming in a variety of settings including caves, soils, the oceans, during burial from hydrothermal fluids, and along faults. U‐Pb dating of carbonates is applicable to almost the entire geologic time scale, with results from Pleistocene speleothems showing great promise for dating records <1 Ma old.

Hematite U-Pb dating of Snowball Earth meltwater events. [PDF]
Proc Natl Acad Sci U S AThe Snowball Earth hypothesis predicts global ice cover; however, previous descriptions of Cryogenian (720-635 Ma) glacial deposits are limited to continental margins and shallow marine basins. The Tavakaiv (Tava) sandstone injectites and ridges in Colorado, USA, preserve a rare terrestrial record of Cryogenian low-latitude glaciation.

U-Pb dating for zircons from granitic rocks in southwestern Cambodia. [PDF]
Heliyon, 2023 U-Pb dating was conducted for zircons from a total of 14 samples from 13 granite bodies in southwestern Cambodia using LA-ICP-MS. The granitic rock samples were collected from southwestern Cambodia, southwest of the Mae Ping Fault extending from northwest Cambodia via Tonle Sap Lake to southern Vietnam.

Uranium incorporation in fluorite and exploration of U–Pb dating [PDF]
Geochronology, 2021 The age of ore deposits constitutes a decisive element in understanding their formation. Deciphering their precise chronology may be a challenge in the absence of mineral phases that can be dated by conventional geochronometers.
