This paper reviews the recent development in imaging of the interior of the Earth. The horizon of a new geodynamic model for the whole Earth is outlined and its significance for human societies emphasized. - (AM)
Rare earth element mobility associated with uranium mineralisation
Extreme rare earth element mobility has been discovered associated with uranium mineralisation in metasedimentary rocks of the Lower Proterozoic Pine Creek Geosyncline, Australia. The rare earth element patterns and other geochemical evidence point
to movement of the rare earth elements and uranium by carbonate complexes in a low temperature, oxidising and alkaline solution.

The interpretation of the large-scale anomalies of geoid heights, gravity, deflection of the vertical has shown that the density heterogeneities disturb the normal flattening of the Earth. The superhydrostatic flattening of the Earth is an illusion
. The earth's lithosphere is sufficiently thin and flexible in order to adapt itself to decreasing of the angle velocity of the earth's rotation. Recent geoid heights should be measured from the hydrostatic ellipsoid with the flattening of I/299.67. On the other
Le but de cette article est de présenter les principaux résultats d'une campagne de mesures au sol effectuée en quasi-synchronisme avec le passage du satellite RADARSAT. Cette campagne s'inscrivait dans le cadre du projet ADRO (039) du laboratoire
The place of geography in the studies on the Man and the Earth system
The system Man and the Earth is investigated by various disciplines starting from the earth and biological sciences upto physics, chemistry, economic, social, agricultural and technical sciences. The geographical sciences should try to keep
The AA. summarize the results of the international symposium The Earth as Transformed by Human Action held at Clark University, USA, in October 1987 with the purpose of inventorying human impact and environmental changes on the regional and global
scales, and on the conceptualization of the human dimensions of global change. Some perspectives of the further development of the international and interdisciplinary Earth Transformed project are also discussed.
