GEODYNAMICS: LOOKING TO THE FUTURE - THE GEODYNAMICS PROJECT

Preface to the Global Geodynamics Project

I review some features of the Global Geodynamics Project during its initial phase of operation 1997–2003. These fall into three categories: (1) instrumental—the development of the superconducting gravimeters during this time; (2) organizational—how the various SG groups have come together to improve their installations and provide their data; and (3) scientific—what have been some of the notabl...

Contribution of the VLBA Network to Geodynamics

A decade of observations in geodetic mode with the VLBA network gave valuable results. Approximately 1/5 of all geodetic observations are recorded in VLBA mode and processed at the Socorro correlator. Ten years of observations allowed us to reliably measure slow intra-plate motion of the VLBA stations located on the North-American plate. It also helped us to achieve scientific objectives of geo...

Alkaline Rocks and Geodynamics

105 Abstract: Origin of A-type alkali feldspar granites is currently the subject of a world-wide debate. Contrasting hypotheses have been proposed, which range from an entirely crustal origin to an almost complete mantle derivation. A-type alkali feldspar granites belong to either unimodal granite (rhyolite)-dominated association, or bimodal gabbro (basalt)-granite (rhyolite) suite. It is argue...
