Evaluating U-Pb accuracy and precision by comparing zircon ages from 12 standards using TIMS and LA-ICP-MS methods

Autor: Stephen J. Puetz, Christopher J. Spencer

Publikováno v: Geosystems and Geoenvironment, Vol 2, Iss 2, Pp 100177- (2023)

U-Pb geochronological studies based on LA-ICP-MS isotopic measurements often require a profound understanding of the accuracy, precision, and preferred ages derived from this methodology. To enhance such awareness, an approximately 60,000 record U-Pb

Applying Popperian falsifiability to geodynamic hypotheses: empirical testing of the episodic crustal/zircon production hypothesis and selective preservation hypothesis

Even though Earth scientists widely recognize the episodic distribution of zircon ages, the cause of the episodes remains unresolved. Two competing explanations have emerged. Some interpret zircon ...

A total of 4344 magmatic U-Pb ages in the range 2300 to 800 Ma have been compiled from the Great Proterozoic Accretionary Orogen along the margin of the Columbia / Nuna supercontinent and from the subsequent Grenvillian collisional orogens forming th

Time series analysis of mantle cycles Part II: The geologic record in zircons, large igneous provinces and mantle lithosphere

Autor: Kent C. Condie, Stephen J. Puetz

Igneous and detrital zircons have six major U/Pb isotopic age peaks in common (2700 Ma, 1875 Ma, 1045 Ma, 625 Ma, 265 Ma and 90 Ma). For igneous rocks, each age peak is comprised of subpeaks with distinct geographic distributions and a subpeak age ra
