High-precision U-series dating of last interglacial events by mass spectrometry: In the late 80's the method was refined by mass spectrometry. Radiometric dating method based on the degree to which secular equilibrium has been achieved between the parent U and the daughter Th U-Th ages obtained by mass spectrometry in corals from Barbados: Thermoluminescence was discovered by Sir Boyle in Burns, S.
Coral used as reference for the U-Th dating method.
After Viktor Viktorovich Cherdyntsev 's landmark book about uranium had been translated into English, U-Th dating came to widespread research attention in Western geology. Potential alternative driving mechanisms for the ice-age cycles that are consistent with such an early date for the penultimate deglaciation are either the variability of the tropical ocean—atmosphere system or changes in atmospheric CO 2 concentration controlled by a process in the Southern Hemisphere.
