Teotihuacan and Mica: What is Mica, a powerful radioactive insulator doing in structures that date back thousands of years? One of the biggest mysteries surrounding the history of Teotihuacan is surely the huge presence of Mica found in the Pyramids of this great ancient city.

Teotihuacan and Mica

Teotihuacan is without a doubt one of the most mysterious places in the Americas. While the incredible complexity and architectural precision are some of the details that have baffled archeologists for decades, the presence of Mica, a powerful radioactive insulator, is perhaps one of the biggest enigmas of this great ancient city. Established around 100 B.C., and lasting until its fall between the seventh and eighth centuries, Teotihuacan was one of the largest cities in the ancient world, with over 150,000 inhabitants at its peak.

As you walk through the city you notice immediately the difference compared to other ancient cities. Teotihuacan is amazing, it is both incredibly futuristic and ancient at the same time. This Ancient City has a modern city layout, you have a Street of the Dead that goes for miles along which you have all of the major ceremonial architecture, including some of the largest buildings ever erected in the New World.

According to archaeologists the advanced design of Teotihuacan suggests that ancient builders had knowledge, not only of architecture, but of complex mathematical and astronomical sciences, and one of the things that are just incredibly amazing and different from all other ancient sites is the fact that from the air, Teotihuacan‘s city layout strangely resembles a computer circuit board with two large processor chips— the Sun Pyramid and the Moon Pyramid. Researchers have also found numerous and remarkable similarities to the Great Pyramids of Egypt.

But just 100 years ago, there were no pyramids (you could see) at Teotihuacan. The staggering four kilometers of the Avenue of the dead and its well-known pyramids of the Sun and the Moon remained hidden from sight. Instead of the Pyramids, strange gentle slopes rose from the ground, equidistant from each other, which led to the assumption that these mysterious hilltops could have been artificial structures. They had been there for centuries, covered with vegetation and soil, forgotten like many other ancient sites.

Curiously, when Hernan Cortes and his men conquered the Aztec empire in the sixteenth century they asked the natives who had built such a colossal city, to what the Aztec replied; We were not the builders of Teotihuacan, this city was built by the Quinanatzin, a race of giants who came from the heavens in the times of the SECOND SUN. The Aztecs were the ancient civilization that named the city Teotihuacan, but they did not know the original name of the city. Teotihuacan can be translated to City where men become gods. The Aztecs named the pyramids of Teotihuacan Tonatiuh and Metal tzaquati ( home of the Sun and the Moon). The Aztec empire told the Spanish that the Pyramid of the Sun was covered with black basalt in the distant past, but when they arrived at the city, it was completely abandoned.

In 1906, a worker digging at the site made one of the most important and mysterious discoveries that would forever change how we looked at Teotihuacan. On the fifth deck of the Pyramid of the Sun, a worker discovered a thick layer of laminated mica covering a huge area. It was an odd place for the material to be found.

At that time, in 1906, mica was invaluable in the market. It was used for the construction of capacitors and was considered an incredibly well-appreciated electrical and thermal insulator which had a melting point over 1,100 degrees Celsius. For some obscure reason, the architects of Teotihuacan placed it there in the second century BC, at the time of the greatest expansion of their civilization. The question was why?

Most of the Mica found in 1906 at Teotihuacan was sold at a great price in the market. But not all of the Mica disappeared from Teotihuacan. Today, there are still a few places where you can find Mica in Teotihuacan. For some mysterious reason, the unknown builders of this great Ancient City managed to extract and transport Mica, and incorporate it into the buildings of Teotihuacan, what no one is able to answer is why? What was Mica used for thousands of years ago? Was it part of some lost ancient technology? If so… what type of technology was it? And is it possible that the builders of the Ancient City were in fact ‘Gods’ as some legends suggest?

Mica has superior electrical properties as an insulator and as a dielectric, and can support an electrostatic field while dissipating minimal energy in the form of heat

Obviously, Mica was not incorporated to these constructions for decoration purposes because you couldn’t see it, so it is clear that this mineral was incorporated into these monuments for another purpose.

Mica is stable when exposed to electricity, light, moisture, and extreme temperatures. It has superior electrical properties as an insulator and as a dielectric, and can support an electrostatic field while dissipating minimal energy in the form of heat; it can be split very thin (0.025 to 0.125 millimeters or thinner) while maintaining its electrical properties, has a high dielectric breakdown, is thermally stable to 500 °C, and is resistant to corona discharge. Muscovite, the principal mica used by the electrical industry, is used in capacitors that are ideal for high frequency and radio frequency. Phlogopite mica remains stable at higher temperatures (to 900 °C) and is used in applications in which a combination of high-heat stability and electrical properties is required. Muscovite and phlogopite are used in sheet and ground forms.

According to tests carried out by the Viking Foundation, discoverer of one of the rooms with Mica, this valuable material had an unmistakable ‘identity card’ saying from where it had been extracted. Being made up of specific trace elements, researchers learned that the Mica used in the construction of Teotihuacan had left a rocky region located more than 3,200 kilometers away from Teotihuacan, more precisely… in Brazil. This itself is a true enigma… how did the builders of Teotihuacan extract nearly 30 square meters of mica in Brazil, transport it nearly intact to Mexico without roads, or advanced means of transportation, thousands of years ago?

This is one of the greatest enigmas no one has been able to answer about Teotihuacan.

    If we could only find the means of equipment that they had used to tap into their power source. Several years ago I read about atmospheric electricity and using it as a power source. I would have to look up all the books’ names in my 30 year old journal but the author had believed the ancients used the atmospheric and earth charge to power a global energy grid. Also mentioning that the future glass domed cities we will build on the Earth will be powered by that system as well. With 1 volt per 3 feet elevation they knew how to collect the charge and concentrate it for their lighting and wireless communications. Anyone who has ever seen a crystal radio that is made with a real crystal and a few simple items know how they can tune in a radio station. Some of us built them in grade school science projects. With this system of information transmission and the human runners news could be sent to centers around the world on their network.

    Some Egyptian ornamental statues seem to be possible transmitters and receivers. The Inca towers may have been transmitters although their equipment is not still there. Grid patterns are being found through Google Earth that indicate a global system of unbelievable scale that was collecting the Earth charge. What did they do with all that power still seems to be as little understood as the need to collect it.
    The actual equipment used with these power sources was probably melted into other useful items or just destroyed by a conquering civilization because they were examples of evil remnants of the prior occupants. We need another library of Alexandria to understand what these engineers of long ago were developing. It is interesting to see the pieces of the past beginning to take shape with more discoveries made for a new understanding of those that have called this Earth home. Seems as though this has been greatly suppressed for millennia due to lack of acknowledged evidence in order to prevent the return of another occurrence.

      “All that power” amounts to about 200MW globally, or about 1/5 of a modern power station. On a related theme, even if we collapsed the entire geomagnetic field it would only supply enough electricity for about 1 year’s worth of global use.

    Yes, the inclusion of significant amounts of Mica in the internal pyramid structure apparently sourced thousands’ of kilometers away is completely bizarre. This suggests some sort of electrical or thermal shielding requirement but for what? Solar flares? There is just no way the Aztecs could have located, extracted and transported this amount of Mica distant Brazil. It would be difficult enough with today’s mining and transport technology.

  • Matthew Anderson

    Guess what Mica mines that supplied them in Mexico were NOT from South America but the American Southeast esp. North Carolina area.

    • redsevers

      Do you have a citation for that? I’d love to learn more.
      I understood that analysis of the mica revealed that it is from the Brazilian area.
      Mica was found in Georgia, in mounds built there.
