Our next members meeting will be on January 21, 2022 starting at 7pm via ZOOM.
We will be having a presentation on Galena by geoscientist Ruth Debicki :  She graduated with a B.Sc in Geology from McMAster University in 1971 and started work with the Ontario Geological Survey.  Over the next 45 years she worked for Provincial and Federal governments in Ontario, B.C., the Yukon and the NWT, for a major mining company, as a Geological consultant and in Geoscience education at Cambrian College and Science North.  I am certain her talk will be very interesting so please all members and non-members are all welcome to attend.

Her presentation- The causes of colour in minerals are mysterious and diverse.  Humans have been collecting minerals for many uses, both as a raw material for use as an ore, but also as pigments and adornment. Colour is the first thing characteristic that people are drawn to when they look at a mineral and what every teacher/professor tells geologist-in-training never to use solely for identification.  What causes colour in inorganic substances is very different than that in the organic world, and is in part, constrained by inorganic chemistry and physics. There are only 5400 known minerals in our world, which is much less diverse than the organic world. 

This talk will dive into the causes of colour in the mineral world, and why some geologic conditions create the benchmark standards for colour within the gem and jewellery world.
