31. PRELIMINARY REPORT ON URANIUM, THORIUM,

2007-6-5  Uranium-Thorium-Lead Concentrations The concentrations of uranium, thorium and lead in the sample from Site 228 in the southern Red Sea are roughly compatible with those in the other two samples. The lead content on this low-residue sample is intermediate between that in the other two samples and so are the uranium and thorium concentrations.

Evolution of uranium and thorium minerals American ...

2009-10-1  The near-surface mineralogy of uranium and thorium provide a measure of a planet’s geotectonic and geobiological history. In the absence of extensive magmatic-related fluid reworking of the crust and upper mantle, uranium and thorium will not become sufficiently concentrated to form their own minerals or ore deposits.

3.8. Uranium Thorium dating

2008-11-23  Uranium-Thorium dating is an absolute dating technique which uses the properties of the radio-active half-life of the two alpha emitters 238U and 230Th. The half-life of 238U is T 1/2=4,470,000,000 y. The half-life of 230Th is comparably short, only T 1/2=75,380 y. When the amounts of uranium and thorium are compared an accurate estimation of the age of

Uranium-thorium-lead dating SpringerLink

Uranium is the 48th commonest element in the Earth’s crust (2.3ppm) and is much more abundant than some perhaps better-known elements such as Ag, Hg, Cd and I. In fact, its world production (excluding the then USSR) was 37 300 tonnes in 1988 (equivalent to 44 000 tonnes of U 3 O 8 ).
