Lena Hancock and Svetlana Tessalina on What have we learnt about dating of gold?

The recent Curtin-GSWA geochemical–isotopic collaborative study of small gold nuggets from WA gold occurrences and deposits has demonstrated our analytical capability to produce isotope data to date native gold. We established the reliable Pb–Pb model ages for gold samples and show that galena inclusions in native gold preserve Pb-isotope compositions compatible with known bedrock in the study areas.

Svetlana Tessalina is an Associate Professor in John de Laeter Centre (JDLC) for Isotope Research, Curtin University in Perth, where she is managing a Thermo‐Ionisation Mass Spectrometry (TIMS) Node. She completed her PhD in Geology and Geochemistry of Ore Deposits, following ore deposits research into metallic mineral deposits geology and their formation processes, which is crucial for her present expertise as isotope geochemist. She was involved in preparation and implementation of large projects dedicated to studies of Urals mineral resources, and currently focusing on metallic mineral deposits in Australia.

Lena Hancock obtained her PhD in 1994 at the Moscow University with a project on the mineralogy of lode and alluvial gold deposits of Russia. As a mineralogist, she has worked at Curtin University and the WA Museum before joining GSWA as a HyLogger Geologist. She currently manages the HyLogger facility, which includes investigation of drillcore mineralogy, and is also undertaking a systematic study of gold in Western Australia.

J. Lynn Sunderland on Tucson in 10 Minutes

J.Lynn Sunderland, from Crystal Universe and Ausrox, is a lover of Gem Shows and regular buyer and seller in Tucson. In 10 minutes (or thereabouts), she will attempt to paint us a picture of the temporary metropolis, often called The Mecca of Minerals, that is the modern Tucson Show. From the Tent Cities to Million Dollar Galleries, J.Lynn will give a speed tour through the oldest and newest shows. From back-alley bargains to the Ultra-Elite Showrooms, Tucson has something for everyone.
