Evolution of Fractal Pore Structure in Sedimentary Rocks [PDF]

open access: yesEarth and Space Science, 2022
Geological processes alter pore spaces over time, and their analysis can shed light on the dynamic fractal structure and fluid flow of rocks over time. This study presents experimental evidence to illustrate that the pore fractal structure evolves with ...

Pore Characteristics of Lacustrine Shale Oil Reservoir in the Cretaceous Qingshankou Formation of the Songliao Basin, NE China [PDF]

open access: yesEnergies, 2020
Shale oil is hosted in nanopores of organic-rich shales, so pore characteristics are significant for shale oil accumulation. Here we analyzed pore characteristics of 39 lacustrine shale samples of the Late Cretaceous Qingshankou Formation (K2qn) in the ...

Organic carbon burial is paced by a ~173-ka obliquity cycle in the middle to high latitudes. [PDF]

open access: yesSci Adv, 2021
Earth’s climate system is complex and inherently nonlinear, which can induce some extraneous cycles in paleoclimatic proxies at orbital time scales. The paleoenvironmental consequences of these extraneous cycles are debated owing to their complex origin.
