A Review of Research Progress on the Analytical Method of Large-n Detrital Zircon U-Pb Geochronology

Yankuang ceshi, 2022
BACKGROUND Detrital zircon U-Pb geochronology is an important tool for identifying sedimentary provenance and determining the maximum depositional age. The numbers of grains for detrital zircon provenance investigations using laser-ablation inductively ...

Detrital apatite Lu–Hf and U–Pb geochronology applied to the southwestern Siberian margin

Terra Nova, 2022
Apatite is increasingly used in sedimentary provenance studies. However, detrital apatite U–Pb geochronology can be challenging due to the presence of non‐radiogenic Pb, its intermediate closure temperature (~350–550°C) and/or age‐resetting by ...

Tools for uranium characterization in carbonate samples: case studies of natural U–Pb geochronology reference materials

Geochronology, 2021
. Laser ablation U–Pb analyses of carbonate (LAcarb) samples has greatly expanded the potential for U–Pb dating to a variety of carbonate-producing settings. Carbonates that were previously considered impossible to date using isotope dilution methods may

Two‐Dimensional Quantitative Comparison of Density Distributions in Detrital Geochronology and Geochemistry

Geochemistry, Geophysics, Geosystems, 2021
Detrital geochronology provides insight into a broad range of Earth Science questions. However, detrital zircon U‐Pb age distributions are inherently univariate, and thus quantitative comparison methods are limited to one‐dimension (1D) and subject to ...

Age and Origin of the Dongping Au-Te Deposit in the North China Craton Revisited: Evidence from Paragenesis, Geochemistry, and In Situ U-Pb Geochronology of Garnet

, 2021
Dongping is the largest Au-Te vein deposit (~120 t Au) in the North China craton, but its age, origin, and setting remain unsolved. Here, we integrate paragenesis, geochemistry, and in situ U-Pb geochronology of garnet to constrain the timing and ...

Geochronology and petrogeochemical characteristics of U-bearing granites in the Dongshang deposit, northwestern Jiangxi, China and its geological significance

Dizhi lixue xuebao, 2023
The Dongshang Uranium Deposit is situated in the southern section of the Ganfang Pluton in the Jiuling Orogenic Belt of northwestern Jiangxi Province. The U-bearing granites consist mainly of medium- to coarse-grained, porphyritic biotite(binary) granite.
