Terra Nova, EarlyView.ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Molecular Investigation of CO2/CH4 Competitive Adsorption and Confinement in Realistic Shale Kerogen
Nanomaterials, 2019 The adsorption behavior and the mechanism of a CO2/CH4 mixture in shale organic matter play significant roles to predict the carbon dioxide sequestration with enhanced gas recovery (CS-EGR) in shale reservoirs.

Solid-liquid organic matter interaction mechanism between kerogen and aromatic compounds
Shiyou shiyan dizhiUnder geological conditions, the initial generation of oil and gas in source rocks reaches saturation before being expelled and migrating, with the adsorption of hydrocarbons by kerogen being a key factor influencing oil saturation.

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1463-1480, August 2026.Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Mars Sample Return (MSR) is the next major frontier in Mars exploration, through which advanced laboratory instrumentation will be used to study Martian samples and answer key questions surrounding Mars' planetary evolution and astrobiology. Non‐destructive, high‐resolution imaging will be critical for preliminary MSR analyses.
