SUMMARY:PESA WA: Alice Springs Field Trip and Core Viewing
DESCRIPTION:PESA WA ALICE SPRINGS FIELD TRIP\nPESA WA is hosting a field trip to Alice Springs in September 2026.  This is a fantastic opportunity to explore the region\, engage directly with field activities\, and deepen your understanding of the area’s geological context. \nStarting in Alice Springs\, the field trip includes three nights of 4-star accommodation\, with breakfast and lunch provided\, along with transport to and from the field. Expert guidance and commentary will be provided by Peter Haines with contributions from Fiona Burns and Simon Lang. The itinerary covers four days of Amadeus Basin geology\, split evenly between two half days viewing cores and two full days in the field. \nDuring the core workshops\, Fiona Burns (Task Fronterra) will lead participants through the Tent Hill-1 core. This well provides a near-complete section through the Lower to Middle Ordovician stratigraphy\, including the Pacoota Sandstone and overlying units. The Pacoota interval is represented by sub-units P3 to P1\, and recent work suggests deposition in a high-energy\, wave- and storm-dominated shoreface to shelf environment\, with a clear influence from nearby river systems. Simon Lang (GeoSed Consulting) will complement this by guiding the group through cores from the Mereenie Field\, including the P4 sub-unit of the Pacoota Sandstone\, offering a broader view of the full stratigraphic succession. \nIn the field\, Peter Haines (DMPE) will lead the group through the Ellery Creek section\, located approximately 90 km west of Alice Springs. This outcrop provides an exceptional\, near-continuous record of northern Amadeus Basin stratigraphy from the Tonian through to the Devonian. The field component will focus on the Larapinta Group\, comprising the Pacoota Sandstone\, Horn Valley Siltstone\, and Stairway Sandstone\, which represent the primary reservoir and source intervals for key regional accumulations such as the Palm Valley gas field\, Mereenie oil and gas field\, and the Surprise oil field. Participants can expect to see well-exposed sedimentary facies\, trace fossils\, and clear expressions of basin evolution\, with a possible extension into Devonian units depending on access conditions. \nBy combining detailed core analysis with regionally significant outcrop observations\, the trip is designed to provide a comprehensive understanding of the stratigraphy and to highlight how depositional environments and systems have evolved. \nThere will also be the opportunity to hunt for fossils\, including trilobites\, within the Horn Valley Siltstone. \nFieldtrip Leader: Peter Haines. \nContributors: Fiona Burns\, Simon Lang\, Charlie Verdel. \n \nItinerary: \nDay 1: PM: Core Store (0.5 day): Tent Hill-1 Pacoota and Stairway sandstone cores led by Fiona Burns. \nDay 2: Field Day: Ellery Creek\, Pacoota Sandstone section (shallow marine/deltaic) led by Peter Haines. \nDay 3: Field Day: Ellery Creek section (revisited) and other outcrops (stromatolites\, Dalmatian Rock) by Peter Haines and Charlie Verdel. \nDay 4: AM: Core Store (0.5 day): Mereenie Field core led by Simon Lang \n  \nCost: \n\nAttendance is open only to PESA members\, including interstate and international members.  Non-members must join PESA to attend.\n$1500.00 per person (includes accommodation\, transport to field areas\, breakfast\, lunch and digital field guide).\n\nPlease note that flights are not included in the above\, and places are limited.

SUMMARY:PESA WA: Expression of Interest Alice Springs Fieldtrip
DESCRIPTION:PESA WA are planning a field trip to Alice Springs in September 2026.  PESA WA are currently seeking expressions of interest from those who would like to join to see if this is a viable trip. This is a fantastic opportunity to explore the region\, engage directly with field activities\, and deepen your understanding of the area’s geological context.  Attendance will be open only to PESA members\, including interstate and international members.  Non-members are encouraged to join PESA to attend. \nDescription: \nThis fieldtrip is designed for geoscientists and reservoir engineers who primarily focus on deltaic and shallow marine successions\, especially those involved in building or updating geomodels. Whether your task involves a simple facies analysis and well correlation across shallow marine and marginal marine systems\, or input of fluvial channel dimensions into a geomodel\, this fieldtrip will benefit you in several ways. \nThe Ordovician Larapinta Group\, Amadeus Basin\, Northern Territory consists of a succession of mostly shallow marine\, mixed clastic and carbonate strata deposited in the epeiric Larapintine Sea of northern peri-Gondwana. The Pacoota Sandstone is a thick (up to 850 m) deposit of siliciclastic rocks straddling the Cambrian-Ordovician boundary in the Amadeus Basin of central Australia. It is a significant hydrocarbon reservoir (e.g. Meernie Field\, Palm Valley\, Tent Hill-1). It contains four stratigraphic sequences separated by datable events\, described by P Haines. These sequences can be recognised and correlated widely in the subsurface. \nThe Stairway Sandstone is a succession of Middle Ordovician siliciclastic sedimentary rocks\, composed of shallow marine sandstones and mudstones\, with calcareous units also common. The thickness of the formation is highly variable\, ranging from 30 m on the shallower southern margin of the basin to 560 m on the northern margin. \nWe will also have the opportunity to hunt for fossils\, including trilobites\, within the Horn Valley Siltstone. \nFieldtrip Leader: Peter Haines. \nContributors: Fiona Burns\, Simon Lang\, Charlie Verdel. \n \nProposed Itinerary: \nDay 1: Fly to Alice Springs. Core Store (0.5 day): Tent Hill-1 Pacoota & Stairway Sst. cores by Fiona Burns. \nDay 2: Ellery Creek\, Pacoota Sst. section (Shallow marine/deltaic) by P. Haines. \nDay 3: Ellery Creek section (revisited) & other outcrops (stromatolites\, Dalmatian Rock) (by P. Haines and Charlie Verdel. \nDay 4: Meernie Field core (0.5 day) by S Lang. Fly to Perth. \nAnticipated approximate costs: \n\n$1000.00 per person (includes accommodation\, transport to field areas\, breakfast\, lunch and field guide).\nCosts without accommodation and breakfast are anticipated to be approximately $300.00 per person.\n\nPlease note that flights are not included in the above.
