In Person - Europe’s geology and mineralisation – New paradigms explained for Earth’s geology and mineralisation using EagleEye© enhanced imagery

2
PD Hours
Join us for this Combined GeoScience Society and South West WA Branch on New discoveries in the structural geology, mineralisation and exploration targeting of Europe.

About this event

Over the last eight years Bob has used his unique EagleEye system to visualise the earth’s deep structural geology. He is building a new structural-geology framework for the Earth.

In this webinar Bob Watchorn will detail his discoveries in Europe to the core-mantle-boundary at 2,900 km depth using Landsat and Seismic tomography plans and sections.

This webinar will explain how this new ability to see structural geology from geophysical images has led to exciting new discoveries and paradigms on the origin of Planet Earth.

Discoveries

  • Discovery of the different continental scale structures associated with the different mineral and energy deposits. This has huge implications for exploration targeting!
  • Has shown that brittle structures extend to the core with sinistral movement in all continents.
  • Late Heavy Bombardment ring structures (to 8000 km diameter) extend from surface to outer core and are particularly prominent in top 600 km.
  • No evidence of a worldwide Mobile Mantle.
  • Earth started cooler, with all original constituents at -100 °C, gradually heated up and is now cooling again.
  • The earth started rigid and only started breaking up perhaps in the Proterozoic.
  • A different method of brittle (glacier type) Plate tectonics only commenced relatively recently.
  • A mechanism for this type of Brittle Plate Tectonics is proposed.
  • There are no lava-lamp plumes – generally lithosphere is insitu replaced.
  • Planar and ring structures down to Core correlate with surface mines.
  • Ascending mineralising fluids from Core; supply, scavenge and deposit minerals up their path.
  • Diamond, metal mine and oil and gas structural geology and targeting can be visualised world-wide.
Speakers

Bob Watchorn

Bob Watchorn was born in Tasmania. He commenced as a geological assistant with Aberfoyle Tin at Rossarden in 1968. He gained an Associateship in Mining Geology at WASM, Kalgoorlie in 1972 and BSc in 1978 at Curtin University. He commenced work with WMC in 1971 in the nickel mines in Kambalda.
After working in the Kalgoorlie and Norseman gold mines he moved to Stawell playing an important role in restarting the mine. At Stawell he completed an MSc at University of Melbourne on the ‘Structural geology and mineralisation of Stawell goldfield’ under the mentorship of Professor Chris Wilson.
He was chief geologist of the large and geologically complex Mt Magnet and St Ives gold operations. After leaving WMC in 1999 he worked as a geological consultant on many Australian and overseas projects. He commenced structural research under excellent mentors Tim O’Driscoll and Pat McGeehan in the 1980s by experimenting with geophysical software to obtain the best detail out of images used in exploration.
This, combined with his extensive 3D structural knowledge, gained from 45 years underground and surface mapping, led to the point where exceptionable (real) detail could be obtained (for the first time) from many images. This forms the basis of his current research.
