Talk:geochronometer

Sense - that which allows geochronometry?

@Pingku: While looking for translations, I found this use: "Radioaktive Isotope und deren radiogene Tochterisotope werden in den Geowissenschaften seit langem als Geochronometer eingesetzt, das den Zeitraum von der Entstehung der Erde bis heute überstreicht." So it's only the radiogenic substances (not the entire mineral) that are referred to as Geochronometer here. Does this sense exist in English too? — Fytcha〈 T | L | C 〉 12:56, 8 November 2022 (UTC)

• Thanks @Fytcha: Maybe. I've found "This new procedure removes limitations on the application of radioisotopes as geochronometers in paleooceanography, as well as providing variable source and sedimentation rates with time." To my thinking this doesn't (yet) demonstrate a new sense. It says the isotopes are to be used as geochronometers, not that they are geochronometers. (I think this is the same as your German als Geochronometer eingesetzt?) Without context, it's not completely clear what the author means. Perhaps such isotopes are to be the basis of new radiometric dating techniques (geochronometers in the first sense). [In support of this interpretation I note that a geochronometer is identified by the isotopes it uses.] Or perhaps they are to be used in the same way as (mineral) geochronometers (which would effectively make them geochronometers in the second sense).— Pingku^dimmi 11:34, 9 November 2022 (UTC)
