Introduction: Fluid inclusion studies have the potential to record various important features of impact sites including the heating effects due to impact, hydrothermal fluid circulation history, the subsequent behavior of exposed rocks at the planetary surface and, of most interest to astrobiology, the preservation of organic matter [1, 2, 3]. “Water is of interest not only from the perspective...

We present a theoretical framework for acoustic wave propagation in metasurface comprising hexagonal lattice of hard spherical inclusions embedded soft elastic medium. Each layer the direction sound is approximated as homogenized with effective geometric and material properties. To account multiple scattering effects resonant inclusions, an analogy between fluid dynamics creeping flows elastody...

Particles that are embedded in fluid membranes or plates can induce bending if they impose a nonzero angle of contact. This bending mediates complicated effective particle-particle interactions. In the absence of tension, these interactions are nonpairwise additive and can result in clusters of particles with specific configurations that give rise to zero total membrane bending energy. Here, we...

Fast-scanning quadrupoles more representatively record LA-ICP-MS transient fluid inclusion signals. This allows to (1) target smaller inclusions than before; (2) accurately polyphase signals; (3) better characterise chemistry.

We study the dynamical response of a fluid membrane to the sudden conformation change of active inclusions linearly coupled to the membrane curvature. The mutual force between two inclusions triggered simultaneously is shown to exhibit a transient maximum much larger than the equilibrium force. Even in the presence of tension, this dynamical interaction is long range over distances much larger ...

Octahedrally-coordinated Cr(3+) possesses peculiar spectral features which made easy to identify it in minerals, even in minor amounts. Chromium has been studied in uvarovite and fuchsite by optical and EPR spectra. Optical, EPR, FT-infrared and EPMA studies have also let to determine the presence of Fe(3+) and Ti(3+) and fluid inclusions within uvarovite and fuchsite. Absorption and scattering...

Quantitative analyses are reported for active (N2, CH4, CO, CO2, H2, O2, HF, HCl, H2S, SO2) and noble (He, Ar, Ne) gases released by crushing and step heating of magmatic-hydrothermal alunite from the Tapajós gold province in Brazil. This is the oldest known alunite (Ar/Ar age of 1.87 Ga), and because it has undergone minimal postdepositional thermal or tectonic strain, it is excellent material...

The study of water in minerals with infrared spectroscopy is reviewed with emphasis on natural and synthetic quartz. Water can be recognized in minerals as fluid inclusions and as isolated molecules and can be distinguished from hydroxide ion. The distinction between very small inclusions and aggregates of structurally bound molecules is difficult. New studies of synthetic quartz using near-inf...
