#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.

Scientists have figured out how to turn Earth’s most abundant mineral into zero-waste battery metals.

The most abundant mineral in earth’s crust is something called olivine: pretty in the gemstone peridot, but otherwise pretty useless.

Now, New Zealand engineers have figured out how to dissolve olivine to yield silica (50%), magnesium (40%) and nickel-manganese-cobalt hydroxide (10%) for lithium-ion cathodes, leaving only brine. #Science #earth #minerals #environment #metals #olivine #geology #battery
