U‐Pb Saturn: New U‐Pb/Pb‐Pb Data Reduction Software for LA‐ICP‐MS

Abstract

ICP-MS data reduction. It has been developed to provide easy interaction with and visualisation of LA-ICP-MS U-Pb datasets, and allows fast and reliable data reduction of hundreds of data-points. Saturn offers dynamic graphic interfaces to quickly view, evaluate, and plot U-Pb and Pb-Pb isotope data. It operates online (or offline), giving the freedom to change parameters and reprocess data at any stage of data acquisition. The main interface allows the user to: (1) choose the best statistics for drift correction, (2) include/exclude offset factors and (3) apply (or not) Pb c corrections in different modes. Signal intensities are displayed in a separate graphic interface that allows users to interact with the time-resolved signal of individual spot analyses. All graphic windows are interactive; any modification to data treatment (e.g., inclusion or exclusion of analyses of reference material, or modification of the timeresolved signal windows) is instantaneously updated on the data tables. Saturn is particularly attractive for beginners in LA-ICP-MS U-Pb geochronology as it is non-commercial, easy to install, and very interactive. Coding information and a version of the software can be accessed at http://www.air.ufop.br.

The hidden passive margins from the birth of SW Gondwana

“…The background data were obtained for 20 s followed by 40 s of laser signal. The LA-SF-ICP-MS data were reduced using the SATURN software (Silva et al 2023), while age calculations, concordia diagrams, and probability density plots (PDP) were done using the Isoplot-Ex application software (Ludwig 2003) and the Java-based Density Plotter program (Vermeesch 2012), respectively. All ages considered are described as 207 The age distribution of DZ ages is mainly controlled by the volume of magma generated in each tectonic setting, their associated fertility, and preservation potential (Cawood et al 2012, Spencer et al 2018).…”

Atomic spectrometry update – a review of advances in environmental analysis

“…Other freeware packages (written in Python) have become available for the reduction of U–Pb data obtained by LA-ICP-MS . One, U–Pb Saturn, offered 256 dynamic graphic interfaces to view, evaluate and plot U–Pb and Pb–Pb isotope data. Online operation gave the operator freedom to change parameters and reprocess data at any stage of data acquisition.…”

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…A new U–Pb/Pb–Pb data reduction software for LA-ICP-MS was also developed by Silva et al 142 This program “U–Pb Saturn” was designed to process hundreds of spot analyses, from a variety of mass spectrometers, for interferences, drift and mass bias. Data is plotted and visualised on concordia diagrams.…”
