U–Pb geochronology of carbonate-hosted Pb–Zn ores reveals plate-tectonic evolution of eastern Asia during the early Paleozoic [PDF]

open access: yesScientific Reports
The Mississippi Valley–type (MVT) deposits reached their maximum abundance during the final assembly of Pangea. The intense orogenic activity during this assembly in relatively low latitudes created abundant opportunities for the migration of sedimentary

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

open access: yesGeochemistry, 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 ...

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

open access: yesDizhi 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.
