Vaca Muerta Unconventional Oil Study—Insights from Organic Geochemistry

open access: yesProceedings of the 7th Unconventional Resources Technology Conference, 2019
We studied the Vaca Muerta (VM) Play (Neuquén Basin, Argentina) focusing on an oil window mature well (VR ~0.9-1.1%) to determine 1) zones of enrichment and depletion, 2) correlation/allocation to produced fluids, and 3) in-situ GOR and PVT characteristics. Zones of saturation versus depletion, total in-place liquids, oil quality and bitumen enrichment

Patagonian Imaginary Nature: Colonial Narratives in Documentary Films on Subnational Spaces (1920–1955)

open access: yesBulletin of Latin American Research, Volume 45, Issue 1, January 2026.
This study contributes to the ongoing historical examination of ecological and postcolonial questions in Latin America through the lens of new media genre narratives. Early 20th‐century documentary films of Argentine Patagonia institutionalised a natural binary opposition, positioning those challenging colonial power relations based on natural ...

Assembling for Water: The Prefigurative Politics of Land Futures in Argentina

open access: yesAntipode, Volume 57, Issue 6, Page 2213-2240, November 2025.
Abstract As in other areas of Argentina, residents from the Norte Neuquino in the northwestern reaches of Patagonia are concerned about the recent advancements of extractivism onto their territories. Their analysis is clear: the environmental crisis is directly linked to a democratic one, and they engage in a wide range of actions to envision and enact

Accretion and Differentiation of Vesta and the Mesosiderite Parent Body Inferred From Ni Stable Isotope Compositions

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present high‐precision Ni stable isotope data for mesosiderites, eucrites, and diogenites to investigate the accretion and differentiation of asteroid 4 Vesta. Ni isotope variations in eucrites and diogenites are dominated by kinetic diffusion and chondritic contamination, rendering them unsuitable for reconstructing Vesta's primitive Ni ...

Modeling Overpressure Development and the Mechanical Behavior of Sediments in a Complex, Tectonically Active Setting: East Coast Basin, New Zealand

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract The East Coast Basin (ECB) is a complex, active convergent margin located on the North Island of New Zealand, where variable but commonly very high overpressures occur in Cretaceous to Pleistocene stratigraphy. Using a consistent set of sediment physical properties and a single value for tectonic compression, a multi‐1D hydro‐mechanical ...

The Silent VOICE—Searching for Geochemical Markers to Track the Impact of Late Jurassic Rift Tectonics

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 10, October 2024.
Abstract A causal mechanism for the Volgian Isotopic Carbon Excursion (VOICE) remains enigmatic. Elemental geochemical profiles of the Deer Bay Formation, Sverdrup Basin, Arctic Canada that record the VOICE and contemporaneous strata are herein examined to provide insight into depositional environments during Late Jurassic‐Early Cretaceous time.
