Abstract: There are over 800 million people in the world that live close to active volcanoes and so understanding how volcanoes work and what triggers volcanic eruptions is crucial in order to reduce risk to humans from volcanic hazards. In the lecture we'll take a journey deep into the volcano to explore why and where we get volcanoes on Earth and what makes some explosive and others not. We'll look at how science can help us to understand how fast molten rock moves to the surface beneath volcanoes. We'll also delve deep into Australia's rich and fascinating volcanic history to determine how likely a future eruption is in Australia, what the warning signals might look like and how much time we may have to prepare should we detect signs of activity.

Bio: Heather Handley’s research unravels the secrets held in the chemistry of volcanic rocks and their minerals to answer questions such as what triggers volcanic eruptions? and how fast does magma travel from its source to the Earth’s surface? Heather holds a PhD in Volcano Geochemistry from Durham University, UK and 1st Class Bachelor of Science (Honours) in Geology from The University of Edinburgh, UK. In 2012, Heather was awarded an Australian Research Council Future Fellowship to advance our understanding of the timescales of Earth-system process. She is Co-Founder and President of the Women in Earth and Environmental Sciences Australasia Network (WOMEESA) and was recently appointed as a Co Editor-in-Chief for Earth and Planetary Science Letters. Heather received a NSW Young Tall Poppy Award in 2014 in recognition of her research excellence and passion for science communication and has led more than 40 outreach events and workshops. She frequently writes for The Conversation, has given over 60 television, radio and print interviews and has featured in documentaries for National Geographic and Discovery Science. She is also mum to two very curious young girls.

Impressions from our last month’s AGM Last month we have held our Annual General Meeting in the Mawson Lecture Theatre at the University of Adelaide. Our GSA SA Division chair Alan Collins led us through the evening, welcoming new and thanking outgoing committee and subcommittee members, giving a retrospective of the last year’s activities, and handing over award medals and prizes to Barry Cooper, Caroline Tiddy, Alice Clement, Tom Burke, and Isabella Clarke. Alan received his S.W. Carey Medal from John Foden. Chris Mays, a Postdoctoral Fellow at the Swedish Museum of Natural History Stockholm, then gave a fantastic talk about the end-Permian mass extinction. The evening continued with a sumptuous dinner at Amalfi (followed by some tasty cocktails, THANX Morgan!!!).

GSA GOLD

The GSA GOLD speaker for Tuesday, 1st June 2021 is Professor John Foden, Associate Head of the School of Earth and Environmental Science, University of Adelaide. He will present a talk entitled: Lessons from Fe isotopes in the understanding of magmas and hydrothermal ores.

Please register here. Following registration, you will be sent a link to attend GSA GOLD on Zoom. Registration for GSA GOLD is free for all GSA members. Non-members can also register for just $10.00.

John Foden is an Emeritus Professor in the Department of Earth Sciences at the University of Adelaide. After an undergraduate degree at ANU, where he was inspired by the teaching and research of Alan White and Bruce Chappell, John briefly entered the minerals industry with a spell working with ESSO Minerals prospecting for copper in

Queensland’s Bowen Basin. John then went to Tasmania and

completed an honours degree under the supervision of Mike Solomon and Rick Varne. After another year or so as a research assistant both in Tasmania and for a while at Macquarie University, he headed back to Tasmania and did a PhD under the supervision of Rick Varne on the geochemistry and petrology of modern arc volcanics from the eastern

Sunda Arc, Indonesia. Since completing his PhD, John has been at the University of Adelaide, first as a post-doc and then as a member of the academic faculty where he was promoted to Professor in 2006. John has twice been Head of the Department Geology and Geophysics (1995-1998 and 2003) and is currently Associate Head of the School of Earth and Environmental Science and head the School’s Post-

graduate school (Research Education Committee). Throughout his

career, John has maintained an active research interest in the issues of the geochemistry and the source of arc magmatism and on the

application of geochemical and isotopic methods to the understanding

of magma genesis both in ancient and modern subduction settings as well as to intra-crustal magma genesis (granites).

GSA Specialist Group in Economic Geology ‘Facets of Exploration’ Webinar

The GSA Specialist Group in Economic Geology invites you to attend the Facets of Exploration Webinar on Wednesday, 16 June 2021. Speaker is Franco Pirajno from the Centre for Exploration Targeting, The University of Western Australia, who will be presenting the talk 'Alkaline complexes and carbonatites'. Time: 1.30 pm - 2.30 pm (ACST: SA, NT) Following registration, you will be sent a link to attend Facets of Exploration on Zoom. GSA Members attend for free and non-members can register for just $10.00. Please register here via Eventbrite

Abstract:

Intracontinental alkaline complexes and carbonatites commonly occur in rift-related settings, best exemplified by the Cenozoic-present day East African Rift System. Examples in the ancient geological record are more difficult to unravel due to subsequent overprinting during tectono-thermal events unrelated to the original rifting. In the present paper, with the exception of the Bayan Obo carbonatite, I have used examples of anorogenic alkaline complexes and carbonatites that are effectively pristine and unaffected by later geological events. In this context, I report on two alkaline complexes and associated mineralisation in Namibia (Brandberg and Erongo) related to the opening of the South Atlantic and the Paraná-Etendeka large igneous province.

With regards to carbonatites and associated mineralisation, I discuss the exceptionally well-preserved Kruidfontein and Goudini in South Africa, Mount Weld and Gifford Creek ferrocarbonatite complex in Western Australia, the controversial Bayan Obo in northern China and the carbonatites of the Mianning- Dechang belt in SW China. It is proposed that all these igneous systems are formed by processes of partial melting in metasomatised lithospheric mantle, induced by upwelling mantle plumes. Furthermore, it is contended that these alkaline and carbonatite igneous systems are formed in the distal sectors of a mantle plume due to lateral transfer of volatiles, resulting in low degrees of partial melting in the metasomatised sub-continental mantle lithosphere.

WOMEESA Virtual Seminar Series

On the first Wednesday of each month a woman in Earth or Environmental science In Australasia will present a seminar about their research and their career pathway. The seminar series aims to increase the visibility of women scientists and provide inspiring role models for other scientists and science educators. Seminars will be hosted live via zoom.

Next seminar: Wednesday 2nd June 2021, 1:30 pm ACST (Adelaide time) Dr. Rachelle Kernen (The University of Adelaide): Creating and Promoting Gender Equity and Diversity in Professional Geological Societies.

Diversity drives innovation. When professional organizations allow gender inequity to persist, they continually lose talented, valuable individuals who drive economic growth and profits. According to membership data collected by the American Association of Petroleum Geologists (AAPG), American Geophysical Union (AGU), and the Geological Society of America (GSA) there is evidence of continued gender inequity in professional geological societies, particularly, in the AAPG. Specifically, there are remaining inequities in the percentage of

women holding leadership and technical positions, publishing articles, giving distinguished lectures, and receiving technical and service awards within AAPG, even when compared to the proportional percentage of AAPG members. Because the AAPG is a major international geoscience professional organization, this inequity greatly contributes to the gender and diversity disparity that we see today in the greater geoscience community. The recent compilation

and comparison of historical AAPG award and leadership role data Register here for zoom details. allow for an opportunity to provide solutions to advance gender equity and give meaningful power to diversity in AAPG’s most visible and prestigious opportunities. By addressing this issue and implementing meaningful measures to improve gender equity, professional societies such as AAPG, can demonstrate tangible efforts to eliminate the discrimination, bias, and barriers many women encounter and support women in having equitable opportunities as professional geoscientists. Upcoming seminars: Wednesday 7 July 2021: Dr. Teagan Blaikie (CSIRO): “Aeromagnetic interpretation of the Tanami Region and northwest Aileron Province”. Wednesday 4 August 2021: Dr. Jacqueline Halpin (University of Tasmania)

Magpie Creek Geological Trail – Sturt Gorge Recreation Park The Field Guide Subcommittee of the GSA SA Division have produced a new geology field guide for the Magpie Creek Geological Trail, in Sturt Gorge Recreation Park. It was compiled by Colin Conor (STEM, University of South Australia) and Cynthia Pyle (Field Geology Club of South Australia). Adelaide is fortunate in having spectacular gorges that dissect the steep scarp-face of the Mount Lofty Ranges. The Sturt River not only displays a fascinating landscape, but also erosion has created a window that allows an excursion into the depth of time. The 244-hectare Sturt Gorge Recreation Park protects the heritage-listed Sturt Gorge Glaciation Geological Site. The site is one of the first places in the world where rocks were found to show evidence of glaciation (Sturtian Glaciation) occurring about 665 million years ago, prior to the existence of animal life. The newly published field guide explains why the landform exists and what the rocks tell us about the history of the Earth, including ancient changes in climate. Clues are given in the rocks that crop out along the steep banks of the Sturt River and its tributary, Magpie Creek. What we see now is a snapshot of the immensity of geological time represented by scraps of geological history written in those rocks. The rocks contain evidence for a lengthy period when the Earth was prone to cyclical freezing. At times glaciation was so extreme that the whole world is thought to have been enveloped extensively or entirely by ice. This period is known as the ‘Cryogenian’, popularly referred to as ‘Snowball Earth’. Two components of the Cryogenian are represented in South Australia – the Sturtian and Elatina (or Marinoan) glaciations. Exposed along Sturt River in the recreation park are sedimentary rocks that were deposited during the Sturtian Glaciation (Sturt Tillite) and that were deformed and folded in the Cambrian at c. 500 Ma during the ancient Delamerian Orogeny. Download this wonderful walk through the ancient glacial rocks of Sturt Gorge here.

Geoscience Pathways Project Update

ATTENTION EDUCATORS

You may or may not be aware that the Australian Curriculum, Assessment and Reporting Authority (ACARA) has recently released some proposed revisions to the Australian Curriculum on April 29. These revisions, if carried forward without change, will significantly impact the teaching of Earth and Space Sciences (Foundation to Year 10) from next year.

For this reason we would encourage all those interested in geoscience education to engage with the public consultation process, open until Thursday 8 July.

ACARA’s consultation website hosts a number of resources, but we expect that you will find the comparative information sheets for Science F-6 and Science 7-10 to be particularly useful, as they outline both the current and proposed curriculum for each year group.
