  1. : 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.

    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

  8. 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.

  21. 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.

    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.
