Pr oviding accurate timeframes on these processes allows conversion to rates and allows temporal frameworks to be established and applied. This context means enhanced models can be generated exploring the production and accum ulation of resources such as groundwaters and hydrocarbons\, evaluating re positories for anthropogenic waste (nuclear\, CCS)\, constraining subsurfa ce biospheres\, and be applied to document the local-global geochemical cy cles at work in these settings. In this presentation\, the spectrum of geo chronologic tools used to document fluids will be examined\, including sho rt-lived isotopes (e.g. 3H\, 14C\, 81Kr) which are introduced at recharge and progressively decrease over time through radioactive decay\, as well a s radiogenic noble gases (e.g. 4He\, 40Ar) which are produced and accumula te in the subsurface. In particular\, this study will focus on how short-l ived tracers may produce a temporal offset\, but how the full spectrum of geochronologic tools can collectively be applied to provide temporal const raints and frameworks to critical subsurface processes and settings.\n DTSTART:20240409T163000Z DTEND:20240409T173000Z SUMMARY:Geotop Seminar Series: Dr Olivier Warr URL:/eps/channels/event/geotop-seminar-series-dr-olivi er-warr-356151 END:VEVENT END:VCALENDAR
