Cooling and Exhumation History of the Paris Basin Southeastern Margin Revealed by Δ47 /U–Pb Carbonate Thermochronology

open access: yesTerra Nova, EarlyView.
ABSTRACT This study applies Δ₄₇/U–Pb thermochronology to the Middle Jurassic carbonates exposed in the southeastern margin of the Paris Basin. By integrating clumped isotope analyses and U–Pb dating of diagenetic carbonates, we reconstruct the thermal and exhumation history of the sedimentary succession.

Occurrence and distribution of barite in the permo-triassic siksikpuk formation along the Brooks Range haul road [PDF]

open access: yes, 1980
Barite commonly occurs in Permian to Triassic age rocks along the north flank of the Brooks Range. The Siksikpuk Formation (Wolfcampian to lowest Guadalupian age) is noted for its barite and is well exposed in the vicinity of Galbraith Lake along the ...

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

open access: yesTerra Nova, EarlyView.
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.

Characteristics of Chang 7 shale gas reservoirs in Triassic Yanchang Formation of Ordos Basin and its exploration and development prospects

open access: yesShiyou shiyan dizhi
As the second-largest sedimentary basin in China, the Ordos Basin has enormous potential for oil and gas exploration. The Chang 7 member of the Triassic Yanchang Formation in the basin is extensively distributed with organic-rich source rocks, covering ...
