After intensive long discussions with AusIMM they have decided to allow my series of AusIMM Webinars be given free to anyone who wants to use them for research. The aim of my research is not to emulate Academia and have members only and pay for use to access my research papers and webinars. AusIMM has certainly entered into the spirit of Open Access Research. Thank you AusIMM😊.
The research and Webinars are continuing. This is absolutely ground-breaking, paradigm changing research made possible by my development of the EagleEye © structural enhancement system. This is currently the only system that can get detailed, focused structural information from gravity, Landsat, tomography, magnetics and other geographical, geological, and geophysical images.
The ability to see these structures has upended a couple of current ‘sacred cows’ 😊!
The Plate Tectonics and the Mobile Mantle systems are as proved as climate change and have been developed using only rudimentary colour contour image interpretation but not using ultra-detailed structural geology. This statement may seem harsh, but that is what has happened. Instead of speculating using perturbations, and their interpretation based on second order assumptions such as heat or wetness, observing the first order direct evidence of structural geology changes everything!

2013-08-13 – AusIMM Webinar on The Watchorn Impact Structure in the NE Yilgarn in Western Australia.
- https://www.ausimm.com/videos/community-event/south-west-wa-branchgeoscience-society—digital-tech-talk-detailed-seismic-tomography-research-into-the-formation-of-the-yilgarn-craton/
This lecture describes the start of my research into the structural geology of Earth by the ultra-enhancement of earth images (Landsat, geophysical, geological and geographical images).
This is the first description of three >800 km diameter impact structures on earth. It correlates the gold mineralisation in the NE Yilgarn to the ring structures associated with this impact. https://www.geotreks.com.au/work/giant-ring-structures/australia/archaean-meteorite-impacts-in-western-australia-real-or-imagined/
and https://www.geotreks.com.au/work/giant-ring-structures/watchorn-probable-impact-structure/
Figure 1 below shows the correlation of the Watchorn, Cauden and Norseman Impact Structures with gold and nickel mineralisation. A rudimentary exploration targeting plan (2019) of the Yilgarn for gold and nickel is shown. With all of the website posts the original, much more detailed research paper, with references, is available at the conclusion of the post. It is well worthwhile to upload this paper.

2019-04-04 – AusIMM Webinar of the Yilgarn Craton in Western Australia.
This research used Seismic Tomography, at 75 km depth, and shows the structural geology, deformation sequence and gold and nickel mineralisation.
**This was the first time, anywhere in the world, that structural geology was able to be obtained from seismic tomography.** https://www.geotreks.com.au/work/giant-ring-structures/yilgarn-geology-tomography/ . This is still the case in 2022?? WHY??
Figure 2 below shows the structural geology, deformation sequence and gold and nickel mineralisation of the Yilgarn Craton.

2020-07-30 AusIMM Webinar on the structural geology, mineralisation and evolution of Africa
This is the first time that Africa has been studied at various depths and in several cross sections using seismic tomography.
The big surprise was that the Earth under Africa is brittle and has transmitted and preserved structures right down to the Outer Core. This has serious implication to our current theory of Plate Tectonics and a mobile mantle!!!
There were 13 posts that transcribed the webinar. The following link is to the 12th post which summarises this startling discovery. https://www.geotreks.com.au/work/giant-ring-structures/african-continent-evolution-research-using-ultra-detailed-landsat-and-seismic-tomography-from-surface-to-2900-km-depth-implications-for-plate-tectonics-continent-formation-and-the-genesis-part-12/
Figure 3 below shows the brittle structures down to the Outer Core and shows no Mobile Mantle? This makes the movement of the plates in Plate Tectonics more complicated. Not impossible, but they would have to move by the same method as a glacier moves – by brittle deformation.

2019-10-03 AusIMM Webinar on research on Australia, North America and China using seismic tomography
The same result occurred as as seen in Africa, of no mobile mantle under North China, was found in this study.
Figure 4 below is of a comparison of China’s seismic tomography at 90 km depth with the Lunar mares. Their close correlation suggests a similar 4.1 to 3.8 Ga Late Heavy Bombardment formation by a series of large impacts. It is from one of my website papers on China. https://www.geotreks.com.au/work/giant-ring-structures/china-geology-of-the-archaean-craton-using-seismic-tomography/

2021-02-23 AusIMM South American Continent Evolution research.
The major findings in this research were the discovery of rigid crust under South America, the postulation of an immoveable barrier from the Arctic to Antarctic under the American continent and the evidence that the heat flow from the core may be partially responsible for mineralisation and mineralisation trends at the surface of Earth. https://www.geotreks.com.au/work/giant-ring-structures/south-america-seismic-tomography-sections-26s-18s-and-5s-and-a-new-core-to-surface-mineralisation-concept/
Figure 5 below illustrates this concept.
6. 2021-10-28 AusIMM Webinar on ‘Did Copper Mining kickstart advanced urban Civilisation’.
This research combines the examination of the oldest megalithic societies with geological research on the megalithic correlation with ancient copper mines. A close correlation was found, suggesting strongly that copper mining and trading was instrumental in kickstarting civilisation and was initially more important than farming. https://www.geotreks.com.au/life/history/geoarchaeology/gobeklitepe-karahantepe-9500-bce-oldest-farmers-miners-ethnicity-and-appearance-part-4/
Figure 6 below shows the spread of farming in Europe and the diverse ethnicity of the people of the Turkey/Israel area 7 – 10,000 BCE. This series is continuing on my website.
7. 2021-04-08 AusIMM North America webinar on New Discoveries in the Structural Geology, Mineralization & Exploration Targeting of North America .
This webinar explores the North American continent to the Outer Core, using Landsat, gravity and seismic tomography, with the same rigid lithosphere discovery as the other continents being noted.
Exploration Targeting exercises were done on the Carlin and Abitibi areas. https://www.geotreks.com.au/work/giant-ring-structures/north-america-africa-seismic-tomography-section-surface-core-2850-km-depth/ .
Figure 7 below shows the brittle lithosphere that extends from the west coast of North America through Iceland, across Europe to North Africa. There is evidence of the Africa/Europe collision and the Glenville line but little evidence of the Mid Atlantic Ridge zone? This is consistent with the narrow width of the South Atlantic Mid Atlantic Ridge shown in the South American webinar. These correlating discoveries in Australia, China. Africa. South America and now North America suggests EagleEye gives consistent structural geology over half the Earth. These findings cannot be easily dismissed.
The next Webinar will be on the structural geology of Europe, tying it in with the African and North American research. See AusIMM website for details.
Well, that gives a broad-spectrum view of one aspect of my research over the last 25 years. To see the different areas of research in more detail click on the ARCHIVE button at the top of my website https://www.geotreks.com.au/archive/ and go to the relevant paper. At the bottom of each post is a button to select the even more detailed paper that the website post was based on.
Happy Researching 😊!!
