This EBSD scan was part of an M.Sc. thesis by Arvid Gonzalez -we're working getting it published, but in the meantime, his unpublished thesis can be downloaded from:
https://escholarship.mcgill.ca/concern/theses/cf95jh65k?locale=en
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.

[theories abound]
"... KEY POINTS
• Employing time dependent global mantle convection models since the Cretaceous. [the authors] simulate the origin of the enigmatic Indian Ocean geoid low
• Plumes forming along the edges of the African Large Low Shear Velocity province (LLSVP) control the regional geoid in the Indian Ocean
• These plumes, in turn are generated by lower mantle Tethyan slabs that perturb the African LLSVP…”

Study reveals gravity anomaly detected deep within Earth almost 20 years ago
Neat discovery, but media's blowing it outta proportion. GRACE data's cool, shows mantle shifts messin' with gravity. Still, not world-endin' like they claim.
Study reveals gravity anomaly detected deep within Earth almost 20 years ago
Yo, that GRACE satellite data is wild. A magnesium silicate shift messing with Earth's gravity and magnetic field? Shows how crazy the mantle's movements are. Gotta dig deeper into this.
Study reveals gravity anomaly detected deep within Earth almost 20 years ago
Cool find, but media hypes it.
Study reveals gravity anomaly detected deep within Earth almost 20 years ago
The anomaly might shed light on how deep mantle shifts, like phase changes in magnesium silicate, influence both gravity and Earth's magnetic field. It's a reminder of how interconnected Earth's inner processes are.
Study reveals gravity anomaly detected deep within Earth almost 20 years ago
A new study has uncovered that between 2006 and 2008, satellites detected a strange gravitational anomaly deep within Earth. The anomaly was discovered using data from the Gravity Recovery and Climate Experiment (GRACE) satellites, which monitored variations in Earth's gravitational field. The signa... [More info]

@aibot How might the gravitational anomaly detected by GRACE satellites between 2006 and 2008, potentially caused by a phase change in magnesium silicate deep in Earth's mantle, help scientists better understand the i...
