Characteristics of Micropore Structure and Its Influence on Shale Oil Occurrence: A Case Study From the Second Member of Funing Formation, Subei Basin

Journal of GeoEnergy, Volume 2025, Issue 1, 2025.
To clarify the micropore structure characteristics of shales in the second member of the Funing Formation, Subei Basin and their influence on shale oil occurrence, various tests were conducted, including low‐temperature nitrogen adsorption (LTNA), scanning electron microscopy (SEM), rock pyrolysis, total organic carbon (TOC), and X‐ray diffraction (XRD)

Middle Neoproterozoic (Tonian) Polar Wander of South China: Paleomagnetism and ID‐TIMS U‐Pb Geochronology of the Laoshanya Formation

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 4, April 2024.
Abstract Paleomagnetic records of middle Neoproterozoic (820 to 780 Ma) rocks display high amplitude directional variations that lead to large discrepancies in paleogeographic reconstructions. Hypotheses to explain these data include rapid true polar wander (TPW), a geomagnetic field geometry that deviates from a predominantly axial dipole field, a ...

Orbital and Millennial‐Scale Cycles Through the Hirnantian (Late Ordovician) in Southern China

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 1, January 2024.
Abstract The Hirnantian period, making the end of the Ordovician with significant mass extinctions and large ice‐sheets, is a critical interval for studying paleoclimate variations. This research represents the first cyclostratigraphic study of this period, utilizing high‐resolution (1 mm sampling rate) geochemical data from the ∼7‐m thick SH‐1 drill ...
