Report of the panel on earth rotation and reference frames, section 7 [PDF]

Objectives and requirements for Earth rotation and reference frame studies in the 1990s are discussed. The objectives are to observe and understand interactions of air and water with the rotational dynamics of the Earth, the effects of the Earth's crust ...

Early impact basins and the onset of plate tectonics [PDF]

The fundamental crustal dichotomy of the Earth (high and low density crust) was established nearly 4 billion years ago. Therefore, subductable crust was concentrated at the surface of the Earth very early in its history, making possible an early onset ...

On the distribution of radium in the Earth's crust and on the Earth’s internal heat

, 1906
Professor Rutherford has given a calculation which suggests that there may be enough radium in the earth to account for the temperature gradient observed near the surface. The question is of great interest from a cosmical point of view.

Melting of cognetic depleted and enriched reservoirs and the production of high Ti Mare basalts [PDF]

Implicit in current understanding of the location of terrestrial enriched and depleted reservoirs is the notion that they are spatially separated. The depleted reservoir on Earth is situated in the upper mantle, and the complementary enriched reservoir ...

U and Th content in the Central Apennines continental crust: a contribution to the determination of the geo-neutrinos flux at LNGS

, 2011
The regional contribution to the geo-neutrino signal at Gran Sasso National Laboratory (LNGS) was determined based on a detailed geological, geochemical and geophysical study of the region.

The Effect of Demineralization on Coal Functional Group Pyrolysis: Rank‐Dependent Dual Mechanisms of Structural Reorganization and Mineral Catalysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal pyrolysis, as a key thermochemical conversion process, is significantly influenced by inherent minerals, yet their role across different coal ranks remains inadequately understood. This study investigates the effect of acid‐washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=

Atmosphere-Ocean-Crust Interactions in Earth's Early Life

Terrestrial, Atmospheric and Oceanic Sciences, 2013
For as long as infalling planetesimals contained some hydrous and carbonate minerals, Earth¡¦s proto-atmosphere had to be formed during accretion and was composed primarily of CO2.
