LUVMI-X: A Versatile Platform for Resource Prospecting on the Moon

Publikováno v: Earth and Space 2021.

Our current knowledge about the Moon's resource potential is limited to remote-sensing measurements and the analysis of Apollo-era samples. Even though there are persistent indications for substantial deposits of water and other volatiles-especially

The LUVMI Volatile Sampler and Volatile Analysis Package for In Situ ISRU Applications on the Moon and Other Airless Bodies

Autor: M. Reganaz, Simeon Barber, J. Biswas, James Schwanethal, P. Reissa, L. Richter, Craig Pitcher, Simon Sheridan

Publikováno v: Earth and Space 2021.

Recent remote sensing missions have established the presence of water-ice in permanently shadowed regions (PSRs) located at the lunar poles, offering the possibility of a source of material for future in situ resource utilisation (ISRU). ISRU offers

LGC-1: A zircon reference material for in-situ (U-Th)/He dating

Autor: James Schwanethal, Martin Danišík, Yuntao Tian, Pieter Vermeesch, Wen Chen, Martin Rittner, Barry P. Kohn, Daniel J. Condon

Publikováno v: Chemical Geology. 454:80-92

A pairwise in-situ (U-Th)/He dating method has been proposed for mitigating matrix-related bias in U and Th measurements using synthetic reference materials. This method requires a natural zircon reference material whose (U-Th)/He age should be homog

Contrasting Mesozoic evolution across the boundary between on and off craton regions of the South African plateau inferred from apatite fission track and (U-Th-Sm)/He thermochronology

Autor: Vhairi Mackintosh, James Schwanethal, Romain Beucher, Andrew Carter, Cristina Persano, Finlay M. Stuart, Roderick Brown, Mark Wildman, Kerry Gallagher

Publikováno v: Journal of Geophysical Research: Solid Earth. 122:1517-1547

The timing and mechanisms involved in creating the elevated, low-relief topography of the South African plateau remains unresolved. Here we constrain the thermal history of the southwest African plateau since 300 Ma using apatite fission track (AFT)

Oligocene-Early Miocene river incision near the first bend of the Yangze River: Insights from apatite (U-Th-Sm)/He thermochronology

Autor: Pieter Vermeesch, James Schwanethal, Xiaoming Shen, Yuntao Tian, Siwei Qin, Dewen Li

Publikováno v: Tectonophysics. 687:223-231

The southeastern Tibetan Plateau is deeply incised by three parallel rivers, the Salween, the Mekong and the Yangtze. The river incision and surface uplift histories of this landscape are hotly debated. This study presents bedrock apatite (U-Th-Sm)/H

The chronology and tectonic style of landscape evolution along the elevated Atlantic continental margin of South Africa resolved by joint apatite fission track and (U-Th-Sm)/He thermochronology

Autor: Cristina Persano, Kerry Gallagher, F. Stuart, Mark Wildman, Andrew Carter, James Schwanethal, Romain Beucher, Roderick Brown

Publikováno v: Tectonics. 35:511-545

Atlantic-type continental margins have long been considered “passive” tectonic settings throughout the entire postrift phase. Recent studies question the long-term stability of these margins and have shown that postrift uplift and reactivation of

Minimising12C3+interference on4He+measurements in a noble gas mass spectrometer

Autor: James Schwanethal

Publikováno v: Journal of Analytical Atomic Spectrometry. 30:1400-1404

Measurements of helium isotopes used for geochronological studies are subject to interferences from 12C3+ and HD+. The 12C3+ interference was studied on a Nu Instruments Noblesse mass spectrometer which has sufficient mass resolution to measure the i

The Canal de las Montanas Shear Zone (CMSZ), southern Patagonian Andes (51–52°S), is a low-grade mylonite belt generated from felsic ignimbritic, pelitic and basaltic protoliths of the Late Jurassic–Early Cretaceous Rocas Verdes basin. The diffe

During its cruise phase, prior to encountering Jupiter, the Cosmic Dust Analyser (CDA) onboard the Cassini spacecraft returned time of flight mass spectra (TOF MS) of two interplanetary dust particles. Both particles were found to be iron-rich, with
