New Geochronological Constraints on the Late Palaeozoic Tarija Basin, Southern Bolivia: Tectonic and Palaeoclimatic Implications

open access: yesTerra Nova, Volume 38, Issue 1, Page 9-18, February 2026.
ABSTRACT The Carboniferous‐Permian Tarija basin of southern Bolivia evolved under major tectonic and climatic influence. The timing of transition from glacially influenced to arid conditions, after the Gondwanide tectonic event, has been based mainly on palynological correlations.

Myanmar and Asia united, Australia left behind long ago [PDF]

open access: yes, 2016
It is well known that western Myanmar is underlain by a continental fragment, the West Burma Block, but there are arguments about its origin and the time of its arrival in SE Asia.

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)

open access: yesTerra Nova, Volume 38, Issue 1, Page 65-76, February 2026.
ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,

U-Pb and Hf isotopic study of detrital zircons from the Wulashan khondalites: Constraints on the evolution of the Ordos Terrane, Western Block of the North China Craton [PDF]

open access: yes, 2006
Detrital zircons from the Wulashan khondalites in the Ordos Terrane, western block of the North China Craton, give U-Pb ages between 1.84 and 2.32 Ga, showing that their provenance was dominated by Paleoproterozoic rocks, much younger than those exposed ...

A database of detrital zircon U–Pb ages and Hf isotopes for the Middle East (Iranian and Arabian plates)

open access: yesGeoscience Data Journal
The detrital zircon records significant information in the ‘source‐sink’ system. With the application of in situ laser ablation technology, a large number of high‐quality detrital zircon data have been published since 2000.

Provenance of Late Paleozoic-Mesozoic Sandstones, Taimyr Peninsula, the Arctic

open access: yesGeosciences, 2013
The sedimentary and provenance characteristics of seven Permo-Carboniferous and two early Cretaceous samples from the Taimyr Peninsula provide information about the latest evolution of Uralian orogeny and the opening of the Amerasian Basin.

Latest Neoproterozoic to Cambrian detrital zircon facies of western Laurentia

open access: yes, 2017
Late Neoproterozoic to Cambrian sandstone units are common in western Laurentia and record initial transgression of the craton after the formation of the western passive margin during the latest Neoproterozoic to earliest Cambrian.
