Ductile vs. Brittle Strain Localization Induced by the Olivine
As it descends into the Earth's mantle, the olivine that constitutes the lithosphere of subducting slabs transforms to its high-pressure polymorphs, wadsleyite and ringwoodite, in the so-called transition zone. These transformations have important rheological consequences, since they may induce weakening, strain localization, and, in …

Another nutty geoengineering idea – Olivine dust
January 22, 2013 9:36 am. Lets put this nonsense into perspective: This olivine is about 2.84 short tons / yard (at the wiki SG of 3.37) At 3 gigatons / year, that's only 1.057 billion yards / year. At 3,097,600 square yards / square mile, that would be a hole one mile square about 341 feet deep per year.
