#KnowledgeBit: #Olivine is one of the primary components of the Earth's upper mantle. It is a common mineral in Earth's subsurface, but weathers quickly on the surface.

For this reason, Olivine has been proposed as a good candidate for accelerated weathering to sequester carbon dioxide from the Earth's oceans and atmosphere, as part of climate change mitigation.

#Lava is a mixture of minerals

Harriened lava is called #basalt. It usually contains a small number of visible #crystals, as in this piece. See those flecks of green? They're crystals of a mineral called #olivine

Andrew Frederiksen (U. Manitoba) gave us a very clear explanation of a better way to analyze shear-wave splitting as a way to probe the fabric (heterogeneities) of the upper mantle under continents.

The red and orange contours of large split times in British Columbia represent aligned olivine from present-day horizontal mantle flow. Splitting in Alberta represents fabrics formed and preserved from the Precambrian.

This afternoon's bike trip was a 37 km round trip in one hour and ten minutes to collect a 20 kg sack of "greensand" olivine for the garden.

I think it's a good example of the efficiency of velomobiles: how they make human power even more effective than when riding a normal bike. Even on the return journey with a headwind and loaded with the sack of sand, it was easy to keep the speed above 35 km/h.

Being able to stow a lot of things inside the aerodynamic form of the bike helps a lot with efficiency. You feel extra weight when accelerating, not so much once you get going.

And why the olivine ? I calculated a few weeks back that in the worst case this last winter our heating could have emitted 105 kg of CO2. This sack is enough to absorb about a fifth of that amount from the atmosphere.

Each time we plant things indoors or in our garden we add a bit of olivine.

Once humanity (especially those of us in the highly emitting richer countries) has reduced emissions by a lot, it's possible to make a bit of a dent by using a product like this. But there's no chance of compensating for ever larger emissions by trying to mine ever larger amounts of olivine.

Wednesday, early afternoon posters at #AGU23
MR31B-0084 Effects of melt-rock interactions on deformation fabrics and rock physical properties in the shallow mantle lithosphere
James Kirkpatrick presenting, but this is the the M.Sc. work of Arvid Gonzalez (now core-logging in n. QC). Other authors are myself and Caroline Seyler (U. Minnesota).

Arvid found that infiltrating mafic melt reduces the preserved strain in mantle olivine.
