The Eucla basement stratigraphic drilling program, funded through the Exploration Incentive Scheme (EIS), was established to investigate the greenfields Madura and Coompana basement provinces that lie between the Albany–Fraser Orogen and Gawler Craton, beneath up to 500 m of cover rocks in the Bight and Eucla Basins, Western Australia.
The workshop will include presentations from the Geological Survey of Western Australia, Curtin University and First Drilling.
Date Thursday 10 September 2015
Time 8.30 am – 5.00 pm
Venue Hyatt Hotel
Location East Perth
Cost FREE but registration is essential.
To register, contact Deenikka Preedy (email@example.com) or 9222 3634. Please also indicate whether you wish to attend the public core viewing of representative sections on Monday 14 September 2015, at the Perth Core Library, Carlisle
The schedule of presentations will soon be available on the DMP website. Short abstracts will be available on the day, and will be posted on the website afterwards.
Stratigraphic drilling program details
During 2013 and 2014 eight diamond holes were successfully drilled, providing 1560 m of high-quality, oriented HQ basement core, and PQ diamond and RC chips of cover rocks from selected holes. The site locations were chosen to investigate and map geophysical domains interpreted in magnetic and gravity data, rather than as specific targets, and to investigate potential host rocks to known mafic intrusions (i.e. Loongana, Haig and Serpent).
Given the large variation in lithologies and structures, both within individual cores and between cores, this drilling program is on track to greatly increase our knowledge of the basement provinces that are missing links in understanding Proterozoic Australian geology. Combined with work on existing EIS co-funded and donated company cores, the new drillcores also provide insight into the prospectivity of the vast region that lies beneath the Nullarbor Plain.
The stratigraphic drilling program has also provided valuable experience and knowledge of the challenging ground conditions associated with drilling in the Nullarbor region. Both RC and mud-rotary techniques have been trialled and assessed as alternative techniques for getting through the cover to basement.

The Geological Survey of Western Australia (GSWA) offers FREE training in its databases and online systems. The training is in the form of a presentation with hands-on interaction in most systems.
The Perth training has been divided into separate sessions: one for prospectors, and one for mining companies/geologists.
Venue: Mineral House, 100 Plain Street, East Perth
The Kalgoorlie training is open to anyone.
Venue: Room 102 (computer lab), Goldfields Institute of Technology, Centre for Engineering and Mining Training (CEMT), Australian Prospectors and Miners Hall of Fame, Kalgoorlie
To register for this free training, send an email to email@example.com including your details (name, company name, telephone number), the location and date of the training you wish to attend.
Did you know that as well as sun, sand, and surf, the little rocky island of Rottnest has some geological features of international significance?
The Geological Survey of Western Australia recently published a pamphlet on some of the world-class geology found on Rottnest to coincide with a Forum Advocating Cultural & Eco-Tourism Inc (FACET) conference in Perth and on Rottnest on Geotourism — Tourism Down Under. Using the pamphlet, you can visit nine geological sites round the island from West End (in the far west) to The Basin (just round the corner from Thomson Bay).
Author Bob Gozzard draws attention to shoreline platforms and notches that are +2.4, +1.1, and +0.5 metres above present day sea level.
At Fairbridge Bluff ancient corals grew about 125 000 years ago — and there is a similar modern coral reef growing today offshore from Parker Point. A snorkel, mask, and fins will give you a great view underwater of about 25 species of coral.
‘Paddy-field’ terraces (so named as they look just like paddy fields!) and algal polygons are beautifully developed at Wilson Bay. The algal polygons are irregular hexagons and pentagons outlined by the growth of brown seaweed, probably due to the grazing habits of herbivorous reef fish, which seem to be responsible for the creation and maintenance of the polygon boundaries.
The free full-colour pamphlet is available from Mineral House, from the Rottnest Visitor Centre, and from other local Visitor Centres catering to the Rottnest visitor. It can also be downloaded free from the DMP eBookshop.
