Ground Surface Temperature History Since the Last Glacial Maximum in Northeast Asia: Reconstructions From the Borehole Geotherms of the International Continental Scientific Drilling Program

Geophysical Research Letters, Volume 50, Issue 8, 28 April 2023., 2023
Abstract Past ground surface temperature (GST), one of the important aspects of paleoclimate reconstructions, can be inverted from borehole temperature measurements. Here, we report continuous 6,100‐m temperature logs in the International Continental Scientific Drilling Program SK‐2e.

Controlling Factors of Organic‐Rich Lacustrine Shale in the Jurassic Dongyuemiao Member of Sichuan Basin, SW China

Geofluids, Volume 2023, Issue 1, 2023., 2023
Organic‐rich continental shale, widespread in the Sichuan Basin during the deposition of the Jurassic Dongyuemiao Member (J1d), is considered the next shale hydrocarbon exploration target in southern China. To identify a shale gas sweetspot and reduce exploration risk, it is of great significance to determine the organic matter (OM) enrichment ...

Geochemical Characteristics of Trace Elements and REEs and their Geological Significance for Uranium Mineralization within the Qianjiadian Sandstone‐Hosted Uranium Deposit, Songliao Basin

Geofluids, Volume 2023, Issue 1, 2023., 2023
The Qianjiadian uranium deposit is a typical interstratified oxidized zone sandstone‐hosted uranium deposit hosted in the Upper Cretaceous Yaojia Formation of the southern Songliao Basin. Despite its significance, little research has been conducted on the relationship between trace elements, REEs, and uranium mineralization in this deposit.
