The evening will feature the following speakers:

Olga Blay Dianite – a relatively new gem-quality rock

Siberian alkaline rocks are known for their unique characteristics and mineral phases. Most would have heard of charoite, but this talk will focus on a new gem-quality rock, named for the late Diana, Princess of Wales.

Olga is a Senior Geologist at the Geological Survey of Western Australia (GSWA) with interest in geological mapping, geochemistry, and study of gold deposits of the State. She graduated from the Moscow State Mining Engineering University and worked initially as a Mining Engineer / Geologist on alluvial gold projects in the Polar Ural region, and later as a Senior Geologist at the Central Scientific Research Geological Prospecting Institute of Non-Ferrous and Precious Metals (TSNIGRI), managing research projects of the epithermal Au–Ag deposits in the Far East regions of RF. Olga completed her PhD in 1995 in Geology and Mineralogy of Gold Ore deposits in the Far East regions focusing on the relationship between processes of hydrothermal alteration and Au–Ag mineralisation. In Australia, Olga worked as a Manager and Consultant in Consolidated Minerals and as a Business Analyst in Gemcom Software, before joining GSWA in 2009.
