Electrically created “Basalt” (Steinbacher 2011, 586)
Michael Steinbacher in his EU Geology website covers these topics and more, and apparently, it seems both granite and basalt can be synthetically created by applying electrical current to dust and soil.
Is it therefore conceivable that at least some of the mountains of the west coast of the United States are gigantic dunes that were petrified? The process of fossilization is associated with a reduction in volume. It generates sharper and narrower contours, a kind of shrinkage.
How could the process of fossilization be imagined? A dune of loose conglomerate can not simply sink into the earth, be transformed by penetrating liquid magma, and come back to the surface as rock, while the typical dune structure and shape is maintained. The process of fossilization must therefore take place at the surface and it must happen quickly. This is where electricity comes into play. On one hand there is the possibility of melting and solidification, when electricity is introduced through the top of the mountain. On the other hand, it may be a direct electrical conversion. Experiments [Steinbacher 2011, 586] have shown that it is entirely possible to transform dust and soil electrically into different types of rocks. The process first melts the material mixture. Then crystals of different size and composition form. Upon further exposure to electricity, they begin to melt itself. Essential parameters are the composition of the material, current and voltage, and the exposure time.
Also, if a powerful electric arc was able to melt surface rocks and thus create basalt it could explain the origin of some basalt formations that appear somehow “orphan”, that is, while they are supposed to come from a volcano, no one knows where it is, or where it was. Like this one, apparently:
