Linking the evolution of terrestrial interiors and an early outgassed atmosphere to astrophysical observations [PDF]
, 2019 A terrestrial planet is molten during formation and may remain so if subject to intense insolation or tidal forces. Observations continue to favour the detection and characterisation of hot planets, potentially with large outgassed atmospheres. We aim to

Annals of Geophysics, 2009 The strong influence of physical conditions during magma formation on Fe equilibria offers a large variety of possibilities to deduce these conditions from Fe-bearing phases and phase assemblages found in magmatic rocks. Conditions of magma genesis and their evolution are of major interest for the understanding of volcanic eruptions. A ...

Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration
Journal of Raman Spectroscopy, EarlyView.This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

Lateral Magma Flow in Mafic Sill‐complexes
, 2016 The structure of upper crustal magma plumbing systems controls the distribution of volcanism and influences tectonic processes. However, delineating the structure and volume of plumbing systems is difficult because (1) active intrusion networks cannot be

Progress in Resource Evaluation Using a Handheld Raman Instrument Developed for Astronaut Missions
Journal of Raman Spectroscopy, EarlyView.Analogue studies were undertaken using a prototype, handheld Raman spectrometer (developed for astronaut usage on the moon) to collect data that would indicate the presence of water and help develop the technology to search for valuable trace elements (such as lithium and caesium).

Boulder of orbicular rapakivi in Taivassalo, southwestern Finland [PDF]
Bulletin of the Geological Society of Finland, 1983 A boulder of an orbicular rapakivi was found in Taivassalo, close to the southern contact of the Vehmaa rapakivi area in southwestern Finland. Many features, e.g.

Setting the Record Straight: The Intellectual Legacy of H. Igor Ansoff (1918–2002)
Strategic Change, EarlyView.ABSTRACT This study presents a comprehensive annotated bibliography of H. Igor Ansoff's intellectual contributions, addressing significant gaps in existing citation databases such as Scopus and Web of Science, which capture only 9 to 15 percent of his work.

Mathematical Modeling of Measured Recalescence Velocities
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT A moving‐boundary problem of synchronous directional and volumetric solidification in undercooled liquid drops is formulated and solved. Directional solidification is caused by the temperature gradient along the spatial direction, whereas volumetric growth of new phase elements is caused by the melt undercooling ahead of the phase transition ...

On the Role of Dissolved Gases in the Atmosphere Retention of Low-Mass Low-Density Planets [PDF]
, 2018 Low-mass low-density planets discovered by Kepler in the super-Earth mass regime typically have large radii for their inferred masses, implying the presence of H$_2$-He atmospheres.
