  abstract = {{T}his study presents the first application of the {U}/{P}b dating method to highly {P}b-depleted diagenetic geodic calcites of the {J}urassic formations of the {P}aris {B}asin that leads to a reappraisal of the palaeohydrological history of this region. {C}omposite {U}/{P}b ages from multiple geodes, combined with delta {O}-18 analyses, reveal two main phases of diagenetic fluid circulations linked with major regional tectonic events. {D}ogger formations recorded a first diagenetic fluid episode at 147.8 +/- 3.8 {M}a, i.e. at the very beginning of the emersion of the basin during the {T}ithonian period and 30 {M}a earlier than previously assumed. delta {O}-18 results confirmed that most of the calcitic cement phases that closed the porosity of these formations precipitated at the beginning of the {C}retaceous period. {O}xfordian formations recorded another major meteoric fluid circulation at 33.5 +/- 2.8 {M}a related to the initial stage of the {E}uropean {C}enozoic {R}ift {S}ystem ({ECRIS}). {C}onsequently, the porosity of the {M}esozoic formations of the studied area may have been closed sooner than previously thought, before the main {ECRIS} rifting phase of {O}ligocene age. {T}his study shows that {U}/{P}b dating of secondary geodic calcite offers a new powerful way for reconstructing the coupled palaeohydrological and diagenetic history of sedimentary basins.},
