EVOLUTION OF OROGENIC WEDGES AND CONTINENTAL PLATEAUX: INSIGHTS FROM CRUSTAL THERMAL-MECHANICAL MODELS OVERLYING SUBDUCTING MANTLE LITHOSPHERE

Vanderhaeghe O.; Medvedev S.; Fullsack P.; Beaumont C.; Jamieson R.A. (2003)

The links between an early phase of orogenesis, when orogens are commonly wedge shaped, and a later phase, with a plateau geometry, are investigated using coupled thermal-mechanical models with uniform velocity subduction ...
EXPERIMENTAL PARTITIONING OF URANIUM BETWEEN LIQUID IRON SULFIDE AND LIQUID SILICATE: IMPLICATIONS FOR RADIOACTIVITY IN THE EARTH’S CORE

Wheeler K.T.; Walker D.; Fei Y.; Minarik W.G.; McDonough W.F. (2006)

Measurable uranium (U) is found in metal sulfide liquids in equilibrium with molten silicate at conditions appropriate for a planetary magma ocean: 1-10 GPa, 1750-2100 °C, 0-28 wt% S, and fO2 2 log units below IW. However, ...
ZIRCONIUM ISOTOPE EVIDENCE FOR INCOMPLETE ADMIXING OF R-PROCESS COMPONENTS IN THE SOLAR NEBULA

Schonbachler M.; Lee D.C.; Rehkamper M.; Halliday A.N.; Fehr M.A.; Hattendorf B.; Gunther D. (2003)

Isotopic anomalies in Mo and Zr have recently been reported for bulk chondrites and iron meteorites and have been interpreted in terms of a primordial nucleosynthetic heterogeneity in the solar nebula. We report precise ...
