Probing Earth’s missing potassium using the antimatter signature of geoneutrinos

Communications Physics
Puzzles exist in our theories of Earth’s formation and bulk chemical composition. Related to these questions is our incomplete knowledge of the planet’s overall heat budget and thermal history.

Radiogenic age and isotopic studies: report 5

, 1992
U-Pb zircon ages of 2658.0 + 1.21-0.8 Ma and 2661 .3 +l.21-1.1 Ma were determined for Je/sic volcanic rocks in the Russell Lake and Clan Lake areas, respective/y, in the southwestern Slave Province. These are some of the youngest supracrustal rocks dated thus far in the Slave Province.

Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade

Nature Communications
Strontium isotope (87Sr/86Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics.

Radiogenic Age and Isotopic Studies: Report 6

, 1992
Cretaceous strata are widely exposed in the northern Yukon and adjacent Northwest Territories, whereas Tertiary to Holocene strata tend to be limited to the Yukon coastal plain, northernmost Richardson Mountains and adjacent to the Mackenzie Delta. However, under Mackenzie Delta and the Beaufort Sea continental shelf there are 14 to 16 km of Upper ...

Radiogenic age and isotopic studies: report 4

, 1991
The Connaigre Bay Group is a sequence of subaerial volcanic rocks (basait, rhyolite) and interbedded sediments that outcrops in the southwestern part of the Avalon Zone, in central Newfoundland. Although not previously dated, it has been considered to be latest Proterozoic in age, based on lithological correlations with the nearby long Harbour Group ...
