Rajlich’s Hypothesis

I met Petr Rajlich, a Czech geologist from the South Bohemian Region, in 2010 during a geological student contest. He told me about his geological ideas that were sometimes really very different from the mainstream. For the first time, I heard about the possibility that Earth might be expanding or that most of the Czech Republic could be a relic of a meteorite hit (Czech Crater).

Petr has an interesting idea that not only a meteorite hit the region of Bohemia, but also influenced the rocks by a physical phenomenon of ultrasonic cavitation (Rajlich’s Hypothesis).

In 2010, I also published a paper together with Petr and Vaclav Benes. I found an interesting monazite sample in Pisek pegmatites with Vaclav and decided to discuss the topic with Petr. Finally, we produced a short paper:

The lamellae inside quartz that were for the first time described by Petr as ‘cavitation lamellae’ or ‘wavefronts’ are a subject of hot debates. There exist various versions of their origin:

  • Ultrasonic cavitation due to a meteorite hit,
  • zonal growths or
  • tensile fractures.

In 2014, I produced a short study together with a colleague from the Technical University in Munich Erwin Isaac Alvarez Polanco. I cite from Wikipedia: ‘It can be assumed that according to high number of wavefronts transferred through the minerals and resulting high number of cavity implosions, the structure of quartz was partially disrupted during the fluidization and the distribution of prevailing pressure was respected during the transfer into a solid state. There could be then preferred a creation of denser quartz in the area of higher pressure. This means a creation of smaller basic molecular Si-O rings. The situation in the area of lower pressure could be opposite. A finding of such harmonic signature of the quartz density is considered to be an option for the hypothesis verification.’ So we decided to make few simple models of quartz with periodic density distribution. And to propose few ways of its future probing. Here you can find our poster:
