U-Pb Dating of Fossils and Calcite: dating the Sedimentary and Paleontological record

We studied the feasibility of using laser ablation inductively coupled plasma mass spectrometry (LA–ICPMS) for U–Pb dating of fossils (vertebrate-invertebrate) and pedogenic calcite. U–Pb dating of hydrogenic and fossil material can be challenging because samples often contain low U levels and variable amounts of non ...

U-Pb dating of columbites: A geochronologic tool to date magmatism and ore deposits

Geochimica et Cosmochimica Acta, 1992
We have developed techniques for the U-Pb analysis of the mineral columbite [(Fe,Mn)(Ta,Nb)2O6], and report U-Pb ages obtained for three early Proterozoic columbites from the Baltic Shield of northern Sweden. The U-Pb ages of these columbites agree with other available geochronological data.

Vesuvianite-new tool for the U-Pb dating of skarn ore deposits

Mineralogy and Petrology, 1992
Vesuvianites from the Early Proterozoic Bjorntjarn tungsten skarn deposit in northern Sweden were dated with the U-Pb and Pb-Pb methods. Low206Pb/204Pb values make the U-Pb dating of vesuvianite rather sensitive to the common lead correction. However, the combination of Pb-Pb and U-Pb data on the same material permits the deduction of precise ages on ...
