Yes, it is chemistry, not physics! Although, according to the official views of geology, granites, syenites are plastic rocks crystallized in the depths of the Earth under high pressure and temperature (physical process). Formation of polycrystalline rock from the melt.
In light of my earlier version that the megalithic remnants, which stand out for their unnaturalness, are nothing more than dumps from the paste thickening of the rock during the leaching of metals from the soil, ore - I will continue this topic. Let us leave the questions of when and by whom it was done. But I will try to reveal the topic: how.
I propose to go from the opposite and argue: what if granites, syenites (it is only of them that bizarre remnants consist) are not igneous rocks and have never been in a molten state, but this is a rock that crystallized into polycrystals through chemical reactions?
What is granite made of? The mineral is formed by:
1. Feldspar - 65%. It is an aluminosilicate rock-forming mineral. Main types:
- orthoclase K [AlSi3O8];
- albite Na [AlSi3O8];
- anorite Ca [Al2Si2O8].
The combination of K and Na species forms alkaline feldspar, and Na and Ca species are called plagioclase. In granite, feldspar is 65-70%.
2. Quartz - 25%. The most abundant mineral in the earth's crust. Chemical formula SiO2. Quartz in granite is from 25 to 35%.
3. Mica - up to 10%, aluminosilicate mineral. Chemical formula R1 (R2) 3 [AlSi3O10] (OH, F) 2, where R1 is potassium and sodium, and R2 is iron, lithium, aluminum, manganese. Mica makes up 5-10% of granite.
If everything is clear with quartz and sand, let's see these 65% of feldspar:
- orthoclase K [AlSi3O8];
- albite Na [AlSi3O8];
- anorite Ca [Al2Si2O8].
Let's remember this. By the way, the main source of clay is the same feldspar, the decomposition of which under the influence of atmospheric phenomena forms kaolinite and other hydrates of aluminum silicates.
And as you can see, the main compounds of feldspar are salts of silicic acid, silicates, only in combination with aluminum - aluminosilicates.
Feldspar aluminosilicates in granite and clay differ essentially only in structure. In clay, it is a nanopowder. There are some forms of crystals in granite.

Could it be that the dissolution of silicates occurred during the leaching of metals from the bowels? How are metals leached? For example, gold?
Cyanide leaching is used by some gold miners to extract gold particles from ore. various chemical reagents are used:
sodium cyanide, neutral calcium hypochlorite (bleach), copper and ferrous sulfates, sodium xanthate, caustic soda (sodium hydroxide), sodium pyrosulfite, ion exchange resin, thiourea, etc. Lime is also used, it is burnt, then crushed in ball mills and diluted with water, milk of lime is obtained. Sulfuric acid is also used in the technological process
I went through these active chemicals used in leaching metals from ore and settled on caustic soda (sodium hydroxide) as the most suitable substance.
Moreover, caustic sodium, when reacted with silicon dioxide, quartz forms a silicic acid salt, as in feldspar.
A solution of caustic soda soaps to the touch. Sodium hydroxide reacts with aluminum, zinc, titanium. It does not react with iron and copper (metals that have a low electrochemical potential). Aluminum dissolves easily in caustic alkali to form a highly soluble complex - sodium tetrahydroxoaluminate and hydrogen. Those. maybe it is possible to extract aluminum from clay, feldspar without electrolysis?
So far, purely theoretically, it is possible that some of the aluminum remained in solution at the ancient ore-processors and reacted together with the formation of silicic acid salts, for example, the formation of albite: Na [AlSi3O8]
Underground leaching.
If leaching is carried out with acids in quartz rocks, then it is interesting to form silica gel during the reaction of acids with silicates:
Silica gel is a dried gel formed from supersaturated solutions of silicic acids (nSiO2 • mH2O) at pH> 5-6. Solid hydrophilic sorbent …
Silica gel is obtained by interaction of sodium silicate (part of feldspar) with acid (one of the methods). The ability of silica gel to absorb a significant amount of water is used for drying various liquids, especially when the liquid being dehydrated dissolves water poorly.
The well-known granule bags from shoe boxes.
There was such a thought. Many people wonder how trees can grow on megaliths? After all, they simply do not have enough moisture to grow and survive on bare stones:
Krasnoyarsk pillars. Large trees on the megalith.
It is quite possible that silica gels (in fact, the same silicon dioxide, but in a different form, structure), which are part of syenites, absorb moisture from the atmosphere and concentrate it. And it is enough for trees even in drought.
I will also add that from almost all the heights, where there are similar stone outliers, streams flow with a decent debit of water. The water is clean, without calcareous carbonates.
This is just a version. Perhaps I am wrong here. But the physics of matter does not contradict ordinary silicon dioxide.

Let's get back to our boring but very important topic of leaching chemistry.
How could you get caustic soda on the spot?
Chemical methods for obtaining sodium hydroxide.
The chemical methods for producing sodium hydroxide include pyrolytic, calcareous and ferritic.
The pyrolytic method of obtaining sodium hydroxide is the most ancient and begins with the production of sodium oxide Na2O by calcining sodium carbonate at a temperature of 1000 ° C (for example, in a muffle furnace):
Sodium bicarbonate (baking soda), which decomposes at 200 ° C into sodium carbonate, carbon dioxide and water, can also be used as a raw material. The resulting sodium oxide is cooled and water is added very carefully (the reaction occurs with the release of a large amount of heat):
The lime method of obtaining sodium hydroxide consists in the interaction of a solution of soda with slaked lime at a temperature of about 80 ° C. This process is called causticization.
The reaction produces a sodium hydroxide solution and a calcium carbonate precipitate. Calcium carbonate is separated from the solution by filtration, then the solution is evaporated to obtain a molten product containing about 92% of the mass. NaOH. The NaOH is then melted and poured into iron drums where it crystallizes.
The rest of the receiving methods are here.
As you can see, you can even get caustic soda using a handicraft method using lime. But it is possible that they got it, as we do now, by the membrane method, in extreme cases by electrolysis. I mean that highly developed civilization that plowed all the bowels of our planet …
Do you know how gold is isolated and precipitated?
Hydrocyanic acid and all the same caustic soda are taken, which give sodium cyanide, which dissolves gold.
In this solution there is a complex (sodium cyanaurate). This solution is allowed to dissolve the gold, and the impurities are not dissolved. Next, zinc is placed in this solution, and pure gold is deposited on its surface.
That's the kind of chemistry …

In this text, I tried to connect thoughts: how can we combine what we call rocks (granite, syenite) and megaliths (if we further develop the idea of underground leaching of metals and thickening of processing waste). It is quite possible that there was no need to thicken it. The silica gel itself turned into crystals. And the jelly-like mass turned into granite. Or silicic acid salts also turned into crystals, forming feldspar minerals. I hope these thoughts will help someone one day create artificial granite, which will be indistinguishable from what we observe in megaliths.
In addition, a brief correspondence and opinion from the point of view of chemistry, analysis and personal experiments of one of my friends, who knows this topic very well:
- If there is feldspar in granite and in clay too, then it can be somehow connected. I am already convinced that granites and syenites are not igneous rocks. This is crystallized mud from the bowels. Granite is mud with sand.
- This is not dirt, but a miracle of an engineering chemical-physical idea! And it’s just a coincidence.
- So, indeed, paste dumps from soil leaching with acids. I remembered the dictum of astrophysicists: granite is a visiting card of the Earth.
- I am inclined to the artificial origin of granite. In its composition, out of all the abundance of elements, only a dozen are present in granite. And with enviable regularity and volume. And moreover, these are very difficult to connect components.
