Focus: Neutrinos Detected from the Earth’s Mantle
http://physics.aps.org/articles/v8/79

The steady decay of long-lived radioactive isotopes within the Earth
heats the planet and also sends out streams of neutrinos, which can
be observed by large detectors. The Borexino Collaboration now
reports a new set of data for such “geoneutrinos” and indicates that
at least some of them originate from the Earth’s mantle. The work
could improve researchers’ understanding of how radioactive decays
help drive internal geophysical processes, including the slow
convection of rock in the Earth’s mantle.

Neutrinos are notorious for interacting with matter extremely
rarely—a light-year-thick wall of lead would only stop half of the
neutrinos flying through—so detection is challenging. But using large
detectors, both Borexino and KamLAND, another international
collaboration, have previously detected geoneutrinos with very high
confidence. With more data, researchers hope to gain further
information about the distribution of radioactive isotopes in the
Earth’s interior and about the amount of heat they deliver to various
subterranean regions.

The Borexino detector, which contains 300 metric tons of a fluid that
can emit light flashes in response to particles, operates at the
underground Gran Sasso National Laboratory in Italy and detects
electron antineutrinos, commonly created in nuclear decays. From
December of 2007 through March of 2015, the detector recorded a total
of 77 candidate geoneutrino events, compared with 46 events the team
reported in 2013 [1].

In a purely astronomical sense, it is possible to extrapolate planetary processes by comparing features of planets distinguished by their rotation or lack thereof.

Venus has no spherical deviation, no crustal evolution and motion but more volcanoes than anywhere in the solar system. More importantly it has only residual rotation.

The Earth has a 26 mile spherical deviation, active crustal evolution and motion at the crustal boundaries and especially at the Mid Atlantic Ridge due to the rapid 1037.5 per hour maximum speed at the Equator and diminishing fairly rapidly towards the polar latitudes.

The exciting ability to link planetary spherical deviation and evolutionary geology via an uneven rotational gradient of the mantle in contact with the fractured crust has been here for over a decade so that genuine researchers can just go ahead and borrow the outlines which link dynamic geology with a rotating Earth instead of a stationary earth ideology of 'convection cells'.

It doesn't matter if it is a decade or multiples of that, the linkage between the overall shape of the Earth and the intricacies of evolutionary geology will borrow on the motion of our great planet.
