In 2010 seed funding through PACE was provided to commence a project that compared the properties of halloysite from a playa lake 60 km east of Maralinga, South Australia (the Camel Lake site), with halloysites from various geological settings within Australia, New Zealand and United States. Halloysite is a member of the kaolin group of clay minerals and typically crystallises as microtubules. The objectives of the project were to raise awareness of geological factors that affect the physical properties of halloysite and to highlight what appeared to be special properties of the Camel Lake halloysite. The investigation has particular relevance to research into potential new applications in nanotechnology that seek to exploit the physical characteristics of halloysite as a natural mineral nanotube. While the extent of Camel Lake halloysite remains to be tested, samples taken from below thin sediment cover at the southwestern end of the dry lake bed have, to date, produced regular, straight halloysite tubules showing consistent range in length, tube wall thickness and diameter of the central cylindrical pore or lumen. The results of the initial PACE-funded project and some of the outcomes that developed from this work, particularly in relation to understanding the conditions of formation of Camel Lake halloysite, its properties and potential uses, are summarised herein.
