PESA SA/NT August Technical Luncheon
The Birkhead Formation: a joint chemostratigraphy-biostratigraphy case study
When: Thursday 29th August, 12pm for 12:30
Where: Ayers House, 288 North Tce, Adelaide
Speakers: Stuart Munday (Chemostrat) & Carey Hannaford (MGPalaeo)
Chemostrat and MGPalaeo will be presenting a joint stratigraphic – provenance study of the late Jurassic Birkhead Formation from the Snatcher Field area, northern Eromanga Basin. New palynological analysis has been integrated with inorganic geochemistry finger-printing to enable the subdivision of this problematic formation with increased confidence and resolution. The data also provides new insight into changes in the environment of deposition and sediment provenance, evident from the spore-pollen assemblage and mineralogical makeup reflected in the geochemistry. This includes the recognition of reworking of Permian taxa, and an increase of volcanogenic material with intermediate tendencies within the formation consistent in all wells. New heavy mineral and zircon geochronology data also acquired for this study highlights the nature and age of provenance components, including penecontemporaneous populations.
Lunch will include a 2-course meal and drinks
Please note that bookings will close at 5pm on Monday 26th August
