PESA WA Technical August lunch talk- End Permian Armageddon asteroid cluster that almost ended life on Earth. Climate change on steroids. Impact on the prospectivity of the Bedout Subasin and surrounds, GNWS, Western Australia

Thursday, 20 August @ 12:00 pm - 2:00 pm (Australia/Perth time)

$39 – $99

Guest Speaker(s): Dariusz Jablonski

Dariusz Jablonski received a BSc in geology from the Western Australian Institute of Technology in 1985. He joined Woodside Offshore Petroleum Pty Ltd where he worked as a basin analyst on acreage assessment, risk analysis, play map generation and building geological databases covering the Westralian Superbasin, the Perth Basin, South and Eastern Australia, Irian Jaya and Papua New Guinea.

From 2001 and 2005 he was involved as a contractor in prospect generation and evaluation of exploration acreage in Australia, Ukraine, East Africa, Mediterranean, UK and Middle East.

Between 2006 - 2016 he was the Exploration Manager of Finder Exploration responsible for both conventional and unconventional exploration acreage in Australia, New Zealand, United Kingdom, Papua New Guinea, Jamaica and Canada. As exploration manager of Finder Exploration his latest successful wells were the oil discovery at Phoenix South-1, gas discovery at Roc-1 and the successful unconventional well test at Theia-1. Dariusz is now Principal Geoscientist with Kato Energy. Dariusz is the author of a number of publications covering the Australian North West Shelf, Indonesia, Papua New Guinea and Argentina.

PESA WA invites you to our August technical luncheon on Thursday 20th August

End Permian Armageddon asteroid cluster that almost ended life on Earth. Climate change on steroids.  Impact on the prospectivity of  the Bedout Subasin and surrounds, GNWS, Western Australia

Presented by Dariusz Jablonski

Abstract:

Australia has several well-documented possible impact structures, both onshore and offshore, and the Bedout High in the offshore Canning Basin, may also have an impact origin.

Using high-resolution modern seismic surveying we identify two penecontemporaneous possible impact structures in the region of the Bedout High. The main Bedout High forms a north-south elongated feature, 150 kms long and 60 kms wide whereas the Bedout East structure is circular, 25 kms in diameter, and illustrates classic impact edge, internal ribbing and concentric fractures superimposed on the pre-existing Palaeozoic structural fabric.
The Bedout High illustrates basement uplift with radiating faults that mimic the elongated dome. Most of these faults terminate at the Permian/Triassic (P/Tr) boundary. On the north-eastern flank of the Bedout High, above the P/Tr boundary, we identify a 4 km-thick sedimentary wedge with numerous volcanic intrusions, which we interpret to be an erosional product when the Bedout area rebounded as a result of the impacts. Volcanics intersected in this zone are also associated with a number of mantle-induced magma domes that began to grow and uplift at the same time (e.g. Tres Hombres/ Raglin structure).
On a global scale, the Bedout impacts may be a part of an asteroid swarm that hit the southern hemisphere within a very short period. The 40 km-diameter Araguainha crater identified onshore Brazil and possibly the 75 km-diameter Gnargoo crater in the Southern Carnarvon Basin may be related to the events observed in the Bedout area. A cluster of at least 3 impactors may explain the severity and global nature of the latest Permian Triassic Main Extinction (PTME) event.
