Seafloor Isochrons Place a Hard Limit on Crustal Disintegration from the Chicxulub Impact

I always thought the entire form of the Gulf of Mexico might be the crater from the Chicxulub impact reputed to have wasted the dinosaurs. My imagination runs with that name. So much to work with. Chicxyclub…well, Club Med impact … Continue reading

Great Mysteries of Nature Nobody Seems to be Thinking About

This list will be changed from time to time and some mysteries will be developed into posts. In some sense they all speak to our lack of understanding of the magnetic and gravitational forces that bear down on us. 1. … Continue reading

Gravity and Magnetism

This post follows the last two which were inspired by discovering that the virtual geomagnetic pole (VGP) wander path during the Laschamp reversal as revealed in Black Sea sediments by the work of Norbert R. Nowaczyk consistently follows lows in … Continue reading

Further Musing on the Affinity of Magnetic North for Gravity Holes During the Laschamp Reversal.

We know so little about what this means that it may be helpful to focus on what the gravity geoid is not. The earth is NOT shaped like a potato. Vertical exaggeration is used on nearly all maps to keep them … Continue reading

Simplified Path of Magnetic North During 41kya Reversal on Current Geoid

There was this really cool Hemholtz plot of the path of magnetic north during the last geomagnetic reversal from wander paths of sediments in the Black Sea. Had a sense that it was avoiding the geoid gravity high knob in Indonesia and decided … Continue reading
