Thermal evolution of the Phlegraean magmatic system
Journal of Volcanology and Geothermal Research, 1999Abstract A series of 2-D conductive/convective numerical models show a rather limited range of possible magma chamber configurations that predict the present thermal regime at Campi Flegrei. These models are calculated by HEAT, which allows continuous adjustment of heterogeneous rock properties, magma injection/replenishment, and convective regimes ...

Journal of Thermal Analysis and Calorimetry, 2007
The thermal evolution of a slate rock sample (Berja, Almeria, Spain) has been studied. The phase minerals identified in this sample were mica (illite), chlorite (clinochlore) and quartz as major components, with minor microcline, iron oxide and a mixed-layer or interstratified phase (montmorillonite-chlorite).

The thermal environment as a moderator of social evolution
Biological Reviews, 2021ABSTRACTAnimal sociality plays a crucial organisational role in evolution. As a result, understanding the factors that promote the emergence, maintenance, and diversification of animal societies is of great interest to biologists. Climate is among the foremost ecological factors implicated in evolutionary transitions in social organisation, but we are ...

Physics of the Earth and Planetary Interiors, 1984
A modification of the Boussinesq fluid assumption is the basis of the present theory of three-dimensional and finite amplitude convection in a viscous spherical shell with temperature- and pressure-dependent physical parameters. The theory is applied to the definition of thermal evolution models for Venus which emphasize the effects of certain physical

Thermal evolution of the earth
Tectonophysics, 1981Abstract Models to study the thermal evolution of the earth have been developed based on a calculation of finite-amplitude thermal convection in an incompressible and viscous mantle with temperature and pressure-dependent physical parameters. The lateral dependences of the variables are resolved through their spherical harmonic representations, while

The Moon, 1972
The thermal history and current state of the lunar interior are investigated using constraints imposed by recent geological and physical data. Theoretical temperature models are computed taking into account different initial conditions, heat sources, differentiation and simulated convection.

The thermal evolution of sporopollenin
Organic Geochemistry, 2000Abstract Micro Fourier-Transform Infrared (FT–IR) spectroscopy in combination with transmitted and reflected light microspectrophotometry relates the chemical and physical properties of sporopollenin during thermal maturation; the physical properties measured being colour, as the chromaticity coordinates a *, b * and L *, (luminance) and the ...

The study of Earth as an object whose history can be understood by application of physical laws dates back 200 years. This tradition is, however, rife with missteps related to as yet undiscovered physics or fundamentally incorrect assumptions. While the former is unavoidable, the latter amounts to self-inflicted wounds that may have forestalled ...

Advances in Space Research, 2006
Abstract The thermal regime of a small celestial body, Kuiper Belt object (20000) Varuna, is considered in the process of its formation by accretion of the protoplanet cloud material as well as during its further evolution up to the present time. We have simulated different formation scenarios of Varuna by varying the accretion time, accretion rate ...

On the thermal evolution of the earth
Earth and Planetary Science Letters, 1980The two principal contributions to the surface heat flow of the earth are the cooling of the earth and the heat production of radioactive isotopes. As the rate of heat production decreases with time the temperature of the interior of the earth also decreases.
