The Wandering Poles

Geology makes use of the fact that fossilised magnetism in igneous rocks, puport to document the field strength and direction of the geomagnetic field during the Earth’s evolution allowing the theory of plate tectonics, for example, to develop. Other examples are the interpretations of crustal rotation from these fossilised remnants of the geomagnetic field, or if we wish to proper about our lexical norms, palaemagnetism marking the inferred position of the palaeopoles (and nothing to do with prehistory Polish people). So a summary of the positions of the poles might be a useful thing to do.

NOAA has the published the data on the their website here, and the graphics are reproduced below

One thing that is crystal clear is that both geomagnetic poles are continually on the move at rates far exceeding any plausible tectonic plate movement, so if remnant palaeomagnetism is proposed as a record of past plate motion, one has to be living in la-la land.

The existing motion is also occurring at a far greater rate than any possible internal mechanism of the Earth is capable of, say currents flowing in the upper mantle for example. Which leads to the conclusion that the geomagnetic field is driven externally and the main candidates would be the co-rotating plasma torus comprising the Van Allen Belts as well as the polar Birkeland currents.  Hannes Alvens solar model would be a useful starting point.

Physical rotation of crustal fragments do need to be accompanied with structures showing rotational features, and not from inferred palaeo pole positions as derived from remnant geomagnetism. After all, the geomagnetic field is anything but a static reference point and evidence of a careening earth in response to external forces also exists.

The problem is the belief that the Earth has been in its present position for the whole of its existence along with the Sun and other solar system members. Historical evidence suggesting otherwise is dismissed as myth. (Which is a strange attitude to have considering the consensus surrounding the modern day myth of Carbon Dioxide Force).

About Louis Hissink

Retired diamond exploration geologist. I spent my professional life looking for mineral deposits, found some, and also located a number of kimberlites in NSW and Western Australia. Exploration geology is the closest one can get to practicing the scientific method, mineral exploration always being concerned with finding anomalous geophysical or geochemical data, framing a model and explanation for the anomaly and then testing it with drilling or excavation. All scientific theories are ultimately false since they invariably involved explaining something with incomplete extant knowledge. Since no one is omniscient or knows everything, so too scientific theories which are solely limited to existing knowledge. Because the future always yields new data, scientific theories must change to be compatible with the new data. Thus a true scientist is never in love with any particular theory, always knowing that when the facts change, so too must he/she change their minds.

    Louis, sometimes new insight from simple examination of known fact comes easily to me and sometimes I am as completely oblivious to connecting the dots as someone with a Ph.D indoctrinated in ignorance.

    I have been aware of geomagnetic pole flight for at least 20 years yet have never made the connection to a VAB/solar driver. The last episode of magnetic reversal that I am aware of was a period lasting 400 years during the Laschamp event 41,000 (+/- 2,000) years ago. This period coincided with an massive increase in cosmogenic 10Be production (Greenland ice cores) and large scale volcanic eruptions resulting in the deterioration of climatic conditions in Europe and Asia that led to the collapse of Neanderthal populations if what we think we know is correct. (Always that caveat)

    “For the first time, we have identified evidence that the disappearance of Neanderthals in the Caucasus coincides with a volcanic eruption at about 40,000 BP. Our data support the hypothesis that the Middle to Upper Paleolithic transition in western Eurasia correlates with a global volcanogenic catastrophe. The coeval volcanic eruptions (from a large Campanian Ignimbrite eruption to a smaller eruption in the Central Caucasus) had an unusually sudden and devastating effect on the ecology and forced the fast and extreme climate deterioration (“volcanic winter”) of the Northern Hemisphere in the beginning of Heinrich Event 4. Given the data from Mezmaiskaya Cave and supporting evidence from other sites across the Europe, we guess that the Neanderthal lineage truncated abruptly after this catastrophe in most of its range.”

    Let’s hope that the current weakening of the geomagnetic field doesn’t continue to progress.

    • Edward,
      The work Gunnar Heinsohn is involved with concerning the Middle Ages of the 1st Millennium CE (AD) has identified a massive climate catastrophe that basically terminated the Roman Period, what I term the RTE, or Roman Termination Event. The evidence is physical and stratigraphical and, to my surprise, geological.

      Geological in the sense that during the lignite mining in the German Garzweiler open-cut mine NW of Cologne, in the Elsbachtel area, overburden consists of massive beds of Pleistocene sands and related sediments. The problem is that these deposits also buried roman water works. The conventional explanation is that the sands covering the water works were colluvium, or locally re-transported material. Looking at the geology of this archeological enigma leads me to conclude that it was the Pleistocene Ice age event that seems to have caused the RTE, as a first pass guess.

      If this is true, then the chronology used to date other geological events becomes problematical. Ice core dating is extremely problematical because ice caps are dynamic and interpreting the stratigraphy of ice is purely based on computer modelling.

      Furthermore the role of Gerry Pollack’s EZ water, in which the phase change from bulkwater to ice involves a transition phase of EZ water which expels solutes and protons, will generate a pseudo layering in the ice. This property of ice is not factored into the modelling.

      It appears that the RTE was accompanies by a global culling of the biosphere and I suspect also associated with serious changes in the geomagnetic field.

      The present geological paradigm, and by extension climate factors, is purposefully restricted to internal geological processes, and solar radiation. There’s zero contribution given to the solar EM circuit as the external engine or fuel for geological dynamics, let alone the catastrophic perturbations caused by passing cosmic bodies and what not.

      If one ignores the numerical dating data and instead rank sediments etc in terms of superposition, lateral facies change, and sequencing based on known archaeological periods, then more sense can be made of geological history in terms of mankind’s memories and traditions.

      The trick is to unshackle ourselves from Lyellian uniformitarianism, and that is not easy to do.

        Louis,

        I CANNOT believe I have completely overlooked the magnitude of this event which I am going to *temporarily* attribute to the 536 AD global climate disruption pending further investigation. This is what happens when one admittedly has a mile-wide breadth of knowledge in many fields that is only 6 inches deep. In my defense I never read a single thing about this in Gibbon’s “Decline and Fall of the Roman Empire” but while the Catholic church may have subsequently scrubbed the books clean the Chinese and others most certainly did not. I guess the reason why can be found in the passage below.

        “In China and Japan, the event was also recorded in great detail. Massive droughts and thousands of deaths. The water wasn’t enough for the people and the land. Hundreds of thousands of square miles became infertile. In the Beishi chronicles, the official history of the Northern Dynasties, mentions that in 536, in the province of Xi’an, 80% of the population died and the survivors ate corpses to survive.”

      • The Koreans also recorded much meteoric activity in the Choson Annals – but these are attributed to Medieval times, not Middle Ages. I don’t think the histories were scrubbed clean as much as the survivors, maybe a generation or two after the event, were totally ignorant and fabricated history to fit their beliefs. So the RTE calamity was probably interpreted as the end of the millennium and calendars dated accordingly. It means astronomical retrocalculation is useless if the solar configuration changed then and more recently as when the West adopted the Gregorian calendar in 1582 AD. This event squares with the Choson annals, so maybe the Earth changed its oribital position slightly…who knows? There are no chronological benchmarks to tie things down. The only possible benchmark record is Leona Libby’s Japanese Cedar record of one tree, and then the radiometric dating has to be taken with a good dose of salt. Tim Cullen at Malagabay.wordpress.com has done much work on this stuff.

        I’m involved explaining how Australian Aboriginals know of geological events dated 1,1000 millions of years ago. Extremely heretical.
