Such covariation suggests a mixing of two endmember fluids at varying ratios--one being a more evolved fluid with elevated Sr isotope ratios and isotopically heavy sulphate, possibly derived from reworked porewater, and the other being a fluid bearing isotopically light sulphate and less
radiogenic Sr isotope signature, possibly representing the original porewater (Maynard et al.
Progressive erosion of Pangaea highland areas during the Middle Triassic probably stripped off the low-ratio sedimentary cover and exposed older, more
radiogenic rocks to weathering that produced material with higher [sup.
In addition, the fact that granites contain elevated concentrations of U and Th means that they are also enriched in
radiogenic lead, especially when compared with
radiogenic lead-depleted basalt and island arc volcanic rocks.
Tracking the
radiogenic carbon content of dissolved organic matter would also be very useful, although significantly more expensive.
led studies of
radiogenic injury in the aftermath of the Hiroshima and Nagasaki bombings, I consider how exposed Japanese bodies became the primary data source for contemporary nuclear science and regulation.
There are two possible explanations for this observation: (1) the Shengli River oil shale was diagenetically altered in association with
radiogenic Sr addition after their precipitation, or (2) the precipitation fluid had high [sup.
Radiogenic heating and latent heat of formation represent key components of this energy budget, but tidal dissipation may be a critical factor in the long term.
The average
radiogenic risk for genetic defect associated to treatments of proximal and distal ureteral stones was found to be 2.
CNN reported in August that the 58 FHMS children who had tumors have already had them removed and are now recovered or recovering from surgery, long before
radiogenic cancers had time to develop.
KamLAND Collaboration, Partial
Radiogenic Heat Model for Earth Revealed by Geoneutrino Measurements.
Characteristics of
radiogenic lower motor neurone disease, a possible link with a preceding viral infection.
Having perfected this method of speleothem chronology with near pinpoint accuracy in previous research over the years in their state-of-the-art
Radiogenic Isotope Laboratory at UNM that Asmerom leads, they were equipped to date the delicate florets that adhered to the top of Naia's body after she fell in the cave.
