Using nanoindentation to quantify the mechanical profile of the Wufeng–Longmaxi Formation in southwestern China: link to sedimentary conditions

Solid Earth
Abstract. The fine construction of a continuous mechanical profile for the Wufeng–Longmaxi (WF-LMX) Formation is crucial for designing hydraulic fracturing projects in shale gas development, which however is generally difficult to achieve by conventional macroscopic mechanical testing methods due to the difficulty in obtaining continuous block shale ...

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 ...

Geochemical and petrographic characteristics of Wufeng-Longmaxi shales, Jiaoshiba area, southwest China: Implications for organic matter differential accumulation [PDF]

, 2019
The organic matter-rich shales in Wufeng-Longmaxi Formation have been considered to be a high-quality source rock and a main shale-gas producer in southern China. As the material basis of shale gas, the organic matter content in shales exhibits a notable

A Case Study on Preservation Conditions and Influencing Factors of Shale Gas in the Lower Paleozoic Niutitang Formation, Western Hubei and Hunan, Middle Yangtze Region, China

Geofluids, Volume 2024, Issue 1, 2024.
The Niutitang Formation of the lower Cambrian (Є1n) is a target reservoir of shale gas widely developed in China’s Middle‐Upper Yangtze region, with the characteristics of being widely distributed, having a big thickness and highly organic carbon abundance. However, the exploration and research degree are relatively low. Based on extensive core sample,
