A very colourful and entertaining talk this week from Dr. Inna Lykova
(Research Scientist and Acting Curator, Canadian Museum of Nature). She showed us the amazing minerals found at the fissure eruption of Tolbachik volcano, #Kamchatka (Mindat.org lists 371 valid minerals, with 153 type localities). These minerals seem to form in a complex chromatographic fumerole system.Photo of zincobradaczekite, a sodium-copper-zinc arsenate

@FaithfullJohn Here's a hand sample photo of a komatiite flow from nearby in the Abitibi of Quebec, also ~ 2.7 Ga.

Mary Kang (Civil Engineering, McGill) gave us an entertaining and possibly hopeful talk (despite the topic) focused on quantifying fugitive methane emissions. One disturbing figure: their survey of inactive (non-producing wells) suggests continuing methane emissions seven times that of Canada's National Inventory Report. Hopeful in that much of these emissions are from a fraction of the total wells and therefor easier to stop.

Massive #hematite later brecciated by quartz veining, From the Soudan ironstone, Ely greenstone belt, Vermilion district of northern Minnesota.
These ironstones are sandwiched between pillow basalts of approximately 2.7 billion years old.

The organizers of #MinCup25 are very clever. Today and yesterday feature three aluminosilicates that are compositionally co-linear!
Diagram from Barton (1982), published in the American Mineralogist.

Today, molybdenum is one of the most common trace elements in the ocean due to oxidative weathering of #Molybdenite. But in the Archean the oceans were reducing, and molybdenum was scarce.
Other nitrogenases evolved to use other transition elements, but Mo-nitrogenase was first, and best.
Molybdenite enables the Earth's biosphere!

#Molybdenite is the primary host for the element molybdenum in the Earth's crust.
Molybdenum is part of the most effective biological molecule for nitrogen fixation (Mo-nitrogenase), which converts atmospheric N2 to a bio-available form.
The grey sphere is Mo; this complex molecule likely evolved more than 3.2 billion years ago.
