In the century since then the techniques have been greatly improved and expanded. Dating can now be performed on samples as small as a nanogram using a mass spectrometer. The mass spectrometer was invented in the 1940…

WebThe Rb-Sr dates ranged from 320 m.y. to 395 m.y. The initial Sr 87 /Sr 86 ratios were between 0.709 and 0.717. The ages are interpreted to be intermediate between the age of the source material and the time of sedimentation and, therefore, are not indicative of …

WebUranium–thorium dating, also called thorium-230 dating, uranium-series disequilibrium dating or uranium-series dating, is a radiometric dating technique established in the 1960s which has been used since the 1970s to determine the age of calcium carbonate materials such as speleothem or coral.
