Although gf had the full standard geophysics education (plate tectonics and all that), he became more interested in geological history when he was looking at the origins of high horizontal stress in rocks.  Later, he had the opportunity to relate all his geophysics data (from his exploration phase) to the 'story'.  gf was trained in the use of geophysics to define geological structures.  That is how oil is found.  He never had any interest in crawling on the ground looking at rocks, except for fun.

His first geology post was a slash at the 'paywall', which formed that cartel of knowledge, known at academia.

Over the paywall

We are of the opinion that when gf first started to blog, he engaged in a massive dump of all the issues that were burning in his brain.  Don't forget, he had previously run a clandestine anonymous site 'Bad Siting', during a time he could not use his real name.  In this blog, he came out of the closet.

Swamp Gas, which apparently attracted the UFO crowd.

After this initial burst, he then started his 'boring story' phase, on anything that popped into his head.


Carbon Cycle -  it is always relevant to look at the larger cycles when assessing the current carbon dioxide rise.

Hotspot Controversy

The gf main contribution was in the geology of Ontario, but his thoughts have languished in the dustbins of failed dreams for Ontario, since it has now become a backwater, repelling major investment.  As gf has explained in his many blogs, the geology is not just flat Paleozoic rock lying on featureless granite, but is controlled by major deep-crustal features that cut the province in N-E lines.  These deep mega-thrusts control the location of earthquakes, oil, natural gas, ancient drainage systems, and horizontal rock stress.

Fault Geology of Hamilton, Ontario

Yet the Pickering Fault urban myth continues to haunt us.  There is no real way to make this die, since there truly must be some minuscule piece of broken rock, which somebody can call a 'fault'.  The fact that it cannot be seen by 3 deep seismic reflection lines, and does not have any seismicity signature, diminishes the importance.  The Hamilton Fault has everything.  Anyway, gf is no longer interested in defining a fault, of which there are billions, but rather an active fault mechanism.

To this we must now add the Great Arkansas Experiment.  To conduct the experiment, they injected huge amounts of contaminated shale water down something like 12,000 ft.  It started earthquakes.  The fault mechanism grew exactly as gf described in his various fault mechanism papers.  It looked like it was going to grow and consume the entire state, but it suddenly stopped when they turned off the water.  Now, nobody gives a dang, but gf remembers....

There are so many posts on Arkansas, it is best to just do a site search.

The Virginia earthquake of 2011 is also an excellent experiment on the use of an artificial lake to inject water into a fault.  Numerous posts were written on this.
