Thermal Evolution of Moon
… other experiments.</p> <p>We propose to use a thermal infrared camera mounted on a telescope to acquire time-series observations of lunar surface temperatures to get a novel insight into the thermal evolution of the Moon over a complete lunar cycle. Half a lunar cycle would account from morning …

Deciphering the thermal evolution of small planetary bodies.
… thesis, I use detailed models of planetesimal thermal evolution to constrain the accretionary histories and structures of a range of different meteorite parent bodies from a variety of observed meteorite properties. This model describes the thermochemical evolution of a planetesimal, from …

Mantle thermal evolution of tidally-locked super-earths
… planet's mantle convection structure and evolution using an axisymmetric finite element fluid convection code, SSAXC. Three punctuating evolutionary steps have been identified. First, a sequence of three initial downwellings form at the antistellar point, the substellar point, and at the …

Thermal evolution of a compositionally stratified earth, including plates
… balance of mantle convection and influences the thermal history of the Earth. To parameterize these effects, a subduction zone was included in a small region of a finite element model for the mantle, which also features an asthenosphere and a mid-oceanic ridge. Velocity boundary conditions were …

Tectono-thermal evolution of Gjelsvikfjella, Western Dronning Maud Land, Antarctica
… Land preserves a high-grade polyphase tectono-thermal history. This belt has traditionally been interpreted as a Mesoproterozoic-age (1.3-0.9 Ga) mobile belt that was later affected by thermal overprint associated with little or no deformation during the Neoproterozoic (0.6-0.5 Ga). Therefore …

Tomographic observations of deep convection and the thermal evolution of the Greenland Sea Gyre, 1988-1989
The thermal evolution of the Greenland Sea Gyre is investigated using both historical data and tomographic results from the 1988-89 Greenland Sea Tomography Experiment. Thermal evolution of the gyre center divides naturally into three periods: a preconditioning phase (November-January), during …

A dynamo case study of Mercury, and the early orbital and thermal evolution of the Moon
… characteristics. This result supports either thermal or chemical stratification at the top of Mercury's core, and suggests that the northern hemisphere mantle could be more convective, which could be caused by moderately elevated concentration of heat-producing elements in that region. The …

Thermal Evolution of MAS, YSZ and GZO Thermal Barrier Coating Materials in Benign and CMAS Rich Environments
Abradable thermal barrier coatings (TBCs) play a crucial role as thermal insulators and dynamic seals in turbine engines. However, the conventional choice, yttria-stabilised zirconia (YSZ), exhibits vulnerabilities, such as sintering induced stiffening, phase transformations, and susceptibility to …

Igneous intrusions and thermal evolution in the Raton Basin, CO-NM: contact metamorphism and coal-bed methane generation
… from long emplacement durations and the very low thermal conductivity of coal is responsible. Intrusions may be very important for methane generation in sedimentary basins.

Temperature-dependent thermal transport properties of major Archean rock types and implications for the thermal evolution of Archean terranes
… to have triggered dome-and-keel formation. The thermal transport properties of these rocks, thermal diffusivity (D), and thermal conductivity (k), are not well constrained, especially at high temperatures as traditional contact methods for measuring these properties may suffer from a combination …

Mineral, fluid and thermal evolution in veins from late orogenic coal basins of the Cantabrian Zone (Variscan, NW Spain)
… useful approach for reconstructing the fluid and thermal evolution in diagenetic and very low-grade metamorphism environments. Here, mineralised fissures within the clastic sedimentary rocks of the Ciñera-Matallana and Sabero Stephanian pull-apart coal basins (Cantabrian Zone, Variscan of NW …
