A LEED structural analysis of the Co(100) surface [PDF]

, 1991
The structure of the clean Co(1010) surface has been analysed by LEED. Application of a recently developed computational scheme reveals the prevalence of the termination A in which the two topmost layers exhibit a narrow spacing of 0.62 Å, corresponding ...

The Electrical Conductivity of the Lower Mantle From High‐Pressure/High‐Temperature Measurements of Pyrolite and Ten Years of Geomagnetic Observations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Electromagnetic sounding coupled with experimental measurements of electrical conductivity (EC) can provide valuable constraints on the thermochemical state of Earth's lower mantle. Here, we report a new set of experimentally determined EC values of pyrolite, a candidate composition of the lower mantle, between 25 and 80 GPa at room ...

In Situ Carbonation of Sedimentary and Igneous Rocks of Ultramafic Composition in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Over 3.5 years of exploration in Jezero Crater, the Perseverance rover has explored several geological units of diverse origins and natures, performing multi‐technique remote analyses of the chemistry and mineralogy of rocks with the SuperCam instrument suite.

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

Meteoritics &Planetary Science, Volume 61, Issue 4, Page 644-663, April 2026.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

The domain matrix method: a new calculation scheme for diffraction profiles [PDF]

, 1992
A new calculation scheme for diffraction profiles is presented that combines the matrix method with domain approaches. Based on a generalized Markov chain, the method allows the exact solution of the diffraction problem from any one-dimensionally ...

Intrusion‐Induced Forced Folding Model for the Origin of Séítah Formation Domes on the Jezero Crater Floor, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The JPL rover Perseverance's investigations of Jezero crater's floor reveal that the ultramafic Séítah formation and the overlying mafic Máaz formation are deformed into a broad, low‐amplitude structural dome. Mastcam‐Z stereo images processed into digital outcrop models, together with RIMFAX ground‐penetrating radar profiles, were used to ...
