Talk title: Weathering history of the petroglyphs of the Murujuga (Burrup Peninsula and Dampier Archipelago) in Western Australia: troubled relationships between rocks, men and birds
Speaker: Dr Erick Ramanaidou, CSIRO Mineral Resources, 26 Dick Perry Avenue, Kensington, WA 6151
Abstract: The Murujuga (Burrup Peninsula and Dampier Archipelago) is located on the western coast of the Pilbara region of WA. It is of irreplaceable cultural and archaeological importance as it contains Australia’s largest and most important collection of aboriginal rock art, essentially as petroglyphs of which more than one million engravings have been documented. The lithology of the Murujuga is dominated by weathered granophyre and gabbro. The petroglyphs were carved by removing a few millimetres of the uppermost iron oxide-rich layer to expose the lighter zone underneath. The contrast between the original reddish background and the lighter coloured etching makes the engravings obvious to the naked eye.
The Murujuga is a textbook example of the collision between ancient and modern times as it also hosts potentially polluting major industrial complexes such as iron ore and salt ports, liquefied natural gas, liquid ammonia and ammonium nitrate plants, railway lines, pipelines and rock quarries. There have been concerns about the effect of these activities on the future stability and longevity of the petroglyphs. Accordingly, since 2003, a number of monitoring studies have been undertaken, including air dispersion modelling, air quality and microclimate; colour change, dust deposition and accelerated weathering, and mineral spectroscopy. The studies were based on seven sites (chosen under the guidance of indigenous elders), two control sites are located on the Dampier Archipelago Dolphin and Gidley islands and the remaining five are further south on the lower Murujuga, closer to the industrial areas. The monitoring study underpins this presentation, as we were allowed to collect a small amount of rock specimens.
This presentation interfaces with an archaeological framework as part of the relationship between rocks, men and birds. It is however, fundamentally, a geological paper that provides new information on the mineralogy, petrology, chemistry and spectroscopy of the weathering profile developed on both granophyre and gabbro. It also shows the impact of bird droppings on the rocks as well as providing an original technique to establish the relative age of the petroglyphs.
About the speaker: Erick is the Research Commodity Research Leader for Iron and lateritic Nickel with CSIRO Mineral Resources based at ARRC in Perth Western Australia. He is the co-chairman and editor of the International Iron Ore Conference (2002, 2005, 2007, 2009, 2011, 2013, 2015 and 2017). In 2008, he received the prestigious Stillwell Medal for his work on the Channel Iron Deposits (CID). Inspired by the natural laboratories of the Hamersley Province in WA and the Iron Quadrangle in Minas Gerais Brazil, Erick has developed genetic models for the giant iron ores; (1) banded iron-formation (BIF) hosted iron ores and (2) channel iron deposits. The development of a suite of multiscale analytical tools for the characterisation of iron ores has been Erick’s scientific ambition from Synchrotron chemical mapping of phosphorus, aluminium and silicon, and Raman and reflectance spectroscopies of iron oxides to dating goethite and hematite using U-Th-He. Characterising large volumes of iron ores has been a challenge for mining companies and the implementation of automated techniques such as the HyLogging System™ have provided the iron ore industry with an objective tool to measure hundreds of km of core. Erick has also applied reflectance spectroscopy for monitoring the aboriginal petroglyphs of the Burrup Peninsula to ensure safeguarding of our state heritage.
