Gary asks - does it also have a rich silica Mantle? However, the article emphasizes that feldspar and quartz were present, similar to the granite of the Earth.
There is also another interesting article in the June issue of the New Concepts in Global Tectonics journal (page 233) (www.ncgt.org) ... 'Migrations of foreshocks and/or volcanic eruptions' (from Blot's migration law) by Giovanni Gregori. Blot claimed that one earthquake can migrate and spark another earthquake elsewhere, or even a volcano. They are capable of chasing each other which is fundamentally what Claude Schaeffer theorised in his 'Chronologie Comparie' (1948) as closing markers during the Bronze Ages.

It is situated in the hollowed out caldera where lava flowed just a few years ago. It has been dubbed the Crater Glacier according ot the operations director of Mount St Helens Institute see also www.mshinstitute.org/index.php/news_and_research/history_of_msh

Earthquake research came up with subduction to account for tectonic activity in some regions of the planet. However, it very quickly became a boon for the developing Plate Tectonics Theory (in the mid 20th century). It appeared to make sense, allied to the idea of sea floor spreading (an adaptation of continental drift). In spite of the beauty of the match there has always been problems - from the first hatchings of Plate Tectonics. Mainstream tended to ignore the mismatches, and the anomalies, thinking it was just a lack of data.
I was watching a BBC television programme the other day on the Messel shale formation. It was fronted by the agreeable Richard Fortey - who was the face in the camera.
At www.icr.org/article/8130 (part one), 8181 (part two) and 8503 (part three) we are told that ice cores must be wrong as the Noachian Flood took place around 4500 years ago - and the ice sheets on Greenland and Antarctica must have formed within that time scale. This is a case of mental gymnastics, even more breathtaking than Gunnar Heinsohn's audacious trunscation of historical records and archaeology.
At www.sciencedaily.com/releases/2015/06/150629162542.htm ... researchers using satellite images of the ancient shores of Lake Chad as well as studying sediments from the lake to calculate its age have come up with some unexpected results. It was subject to rapid change - turning from a huge lake much bigger than the modern counterpart, over a short period of time. Most of what was a lake is now a region of sand dunes, rocks and dust.
Derek Ager's book, 'The Nature of the Stratigraphic Record' (Halstead Press:1973) is a geological gem. It is written by somebody who has been described as a neo-catastrophist. Unfortunately, unlike astronomy, in geology a neo-catastrophist is a bit of a wet fish, a uniformitarian who is prepared to accept that natural disasters such as mega earthquakes and big volcanoes may have occurred. The idea that catastrophes with a cosmic dimension have also occurred is not an area they are prepared to delve into - too deeply.
