| Résumé | (disponible en anglais seulement)
The Jackass Mountain Group (JMG) is a thick (1000's of metres) Lower Cretaceous siliciclastic succession that crops out along the southern margin of the Nechako
Basin, a Mesozoic-Tertiary sedimentary basin in the west-central interior of British Columbia considered underexplored for hydrocarbons. A possible correlative to thick subsurface Lower Cretaceous successions known to exist in the subsurface of the
Nechako Basin, our detailed analysis of JMG architecture and reservoir potential suggests that the JMG, previously interpreted as dominantly the result of submarine fan deposition, actually comprises a vertically and laterally complex system with
non-marine, shallow marine and sub-wavebase fan marine deposits. All deposystems include thick successions with extensive moderate- to well-sorted sandstone facies, potentially high priority targets for hydrocarbon exploration if these surface
strata continue to the north into the subsurface of the Nechako Basin. |
