Analysis of lead isotopic ratios of glass objects with the aim of comparing them for forensic purposes

Isotope analyses on leads in iron sulfides and trace galenas from two deposits (Big Ledge, British Columbia and Quemont Mine, Quebec) suggest that variations in the isotopic composition may be influenced by postmineralization alteration of ore. It is postulated that when the ore has been subject to regional metamorphism after emplacement, the metamorphism has homogenized the lead isotope ratios throughout the ore body as appears to have happened at Big Ledge, whereas, if postore activity is limited to minor hydrothermal alteration, as at Quemont, then the lead may be left with a wide range of isotopic composition.

Isotopic Fingerprinting

Common lead isotopic compositions have been determined on feldspars from meta-igneous rocks from nine tectono-stratigraphic terranes or subterranes in east-central Alaska. Most of the terranes have distinct and well-defined signatures in terms of isotopic composition; thus, most can be distinguished on conventional lead isotopic diagrams. Lead isotopic ratios provide evidence for (1) possible sources for the igneous rocks, (2) time of metamorphism, (3) correlation of terrane fragments, and (4) delineation of juxtaposed terranes. Determination of lead isotopic ratios from igneous rocks can be useful in characterizing tectono-stratigraphic terranes (as to mantle or crustal origin) and in correlation, particularly where terrane relationships are enigmatic.

Environmental contextLead is a toxic trace element, widely distributed in the Arctic environment as the result of both natural and anthropogenic processes. High-precision measurements of lead’s isotopic composition are used to distinguish the possible sources and track the transport pathways of this toxic metal. These measurements can provide unique global information on the history and status of lead contamination. AbstractPublished data of lead isotopic ratios in the Arctic environment have been gathered in a dataset file (available as supplementary material) and reviewed to summarise the main information obtained for the different environmental compartments (atmosphere, cryosphere, lithosphere, hydrosphere and biosphere). The analytical procedures applied to achieve the precise measurement of this important environmental proxy are also illustrated and discussed. Finally, a general overview of the sources of atmospheric lead across the Arctic is provided.
