Those who are interested in mysterious views of granite and syenite outliers admire their unusual shapes of walls, pillars and their structure. They ask questions: how could such strange in geometry "blocks", "crumpled stones" have formed? Indeed, at first glance it seems that they were molded block-wise by a hand of reason.
The author of these lines also found paradoxical moments in their structure. For example, the mating planes of the individual array. Precisely adhesion, not fracturing. Lying on top of each other like pancakes rushes, etc. And except for the answer that this is all the result of intelligent forces, the plan of which we do not understand now - nothing came to mind.
Sometimes you have to look elsewhere for answers. It happens that you come across an analogy that can shed light on at least some of the issues. This happened this time too: I drew attention to the blocks of stones located on the coast of the Gulf of Thailand. I decided to share my observations from the analogies I saw.
Here's what I saw when I looked at the stone massifs in new places for me:
Outputs of fossilized masses from the water in the coastal zone of the Gulf of Thailand Province of Chanthaburi.
The photograph does not convey that it looks like the raised plastics that were previously deposited at the bottom. Their appearance is very similar to the Siberian outlier rocks.
At the very coastline there are such stones with strange erosion.
If you zoom in, you can see a grid of random cracks filled with some other rock that is less susceptible to destruction by the sea.
Promotional video:
This is a small stone, about 2mx0.5m in size. There is no doubt that this is precisely petrified sea silt. Its structure contains fine sand. But all the same cracks filled with foreign rock are visible on it.
In places it flakes off like plaster. Some parts of the breed are kind of bloated. Perhaps this indicates the process of increasing mass during petrification. I described the version with such a mechanism here.
The composition, most likely, contains compounds that are contained in bentonite clays - upon contact with a large amount of water, they begin to swell.
Here is what was previously encountered in their native lands:
This is the inner corner formed in the massifs on the Krasnoyarsk pillars.
At first glance, this example is not explained by fracturing, but precisely by the adjoining with the formation of a kind of finer-dispersed "crust" between the masses, which peels off like plaster. Unfortunately, photography does not convey well.
Plaster on syenite massifs. There, on the Krasnoyarsk pillars. Geology does not explain how it was formed. But it is very similar to filling cracks with some kind of rock - as in the stones by the sea.
What is this process of filling cracks in the rock and what kind of mineral is formed - a question for geology.
Isn't it a miniature megalithic remnant rock? The same chaotic seams, cracks, rock influx.
Compare with a similar example from the Krasnoyarsk pillars:
If you do not know which photos are from, you can get confused.
Koiskoe Belogorie.
Let's go back to observations of arrays by the sea:
Another small stone massif near the coast. Scale it up to the scale of the Krasnoyarsk pillars - the analogy is very similar.
Part of this stone is magnified. Pseudo-layout, the influx of one "block" to another, fracturing, giving this whole picture a mystery. Although the size of a part of this stone in this photo is 0.5x0.5m.
The impression that the stone mass increased in size, finding itself on the surface of the earth.
Far from the coast, in the park of a hotel, I discovered a piece of marble with veins, which decays very quickly in a maritime climate:
It collapses separately with the formation of some chaotic form of segments. The cracks are also filled with a different rock, different from marble in color.
A mesh of cracks is visible.
Most likely, in 10-20 years, this piece of marble will collapse on them separately. Metamorphism, as geologists say. But the process is very similar, as in photographs from the coastline, only this happened without increasing the volume of the rock itself.
***
What conclusion can be drawn from these analogies? I think that the processes in the miniature of individual stones and in the macro-objects of entire rocky outcrops are the same. The mechanism of fracturing, metamorphism works in the same way in the polycrystalline structure of similar rocks. Sometimes other minerals form in the cracks, veins, as they say. Perhaps this is the mechanism of crystal growth, maybe the cracks are filled with moisture, and the processes of separation of elements from the donor rock are already beginning in it. The question is interesting and requires deep study. But, unfortunately, geology is content only with the fact that it was already formed supposedly millions of years ago, gives a name to minerals, rocks and puts an end to it. Although, it is too early to put an end to it.
