Low-temperature olivine rheology at high pressure

San-Carlos olivine rheology was investigated at pressure (P) up to 9 GPa and temperature (T) lower than 890 ◦C. Six powder specimens were cold compressed and sintered into dense and compact materials, then deformed during relaxation experiments carried out at constant pressure and temperature in DIA-type cubic-anvil apparatus. Sample elastic strain was monitored during relaxation by in situ X-r...

Low Temperature Hydrothermal Synthesis from Dolomite or Calcite, Quartz and Kaolinite

Dolomite or calcite, quartz and kaolinite in various proportions were reacted at 250-300~ temperatures and pressures up to 90 bars in a hydrous environment. Reactions which approached completion produced talc, calcite, montmorillonite, anorthite (both metastable hexagonal and stable triclinic polymorphs) and the rare Ca-zeolite, garronite. These reactions are applicable to diagenesis, low-grade...

Rheology across the zero-temperature jamming transition.

Many soft-matter systems show a transition between fluidlike and mechanically solidlike states when the volume fraction of the material, e.g., particles, drops, or bubbles is increased. Using an emulsion as a model system with a precisely controllable volume fraction, we show that the entire mechanical behavior in the vicinity of the jamming point can be understood if the mechanical transition ...

Do fish acclimated to low temperature improve microcirculatory perfusion by adapting red cell rheology?

We have measured the rheological properties of individual red blood cells from fishes inhabiting different thermal environments and have also investigated the effects on red cells of acute in vitro temperature changes. The membrane shear elastic modulus (rigidity) increased markedly with decreasing temperature, and the dependence was similar if temperature was varied acutely in vitro or if cell...

Shock temperature in calcite (CaCO3) at 95^160 GPa

The temperatures induced in crystalline calcite (CaCO3) upon planar shock compression (95^160 GPa) are reported from two-stage light gas gun experiments. Temperatures of 3300^5400 K are obtained by fitting six-channel optical pyrometer radiances in the 450^900 nm range to the Planck gray-body radiation law. Thermodynamic calculations demonstrate that these temperatures are some 400^1350 K lower...
