Recently, an international team of researchers discovered a geological “passage” linking the Galapagos Islands to Panama. There are discoveries on our planet that surprise us. However, in this case they only confirmed suspicions that already existed.
They conducted an investigation that yielded good results
When they detected volcanic activity in Panama, geologists began an investigation. This Central American country is far from any active volcano. For decades scientists and geologists searched for the origin of this exotic activity without finding an answer.
Recent research discovered that the igneous rocks are drawn through an underground “passage” that originates in the Galapagos. These islands are located 1609 kilometers away from Panama. This phenomenon was unknown to geological science. Although they suspected that something similar might be happening.
In the study, published in PNAS, the scientists detail the finding. The rocks recovered in Panama were analyzed. They detected that they have the same chemical composition as rocks from the Galapagos Islands.
The discovered geological passage is 100 kilometers deep
The discovered geological passage is a magma channel that lies about 100 kilometers below the surface. This channel allows rocks to move through the “mantle wind” to the center of Panama.
According to the authors of the study, the geological material can have different compositions. They found that, at some sites in Central America, the samples may be strange. This exotic geological material was found in Panama and behind the volcanic arc of Costa Rica. The analysis showed that they are the same as those found in the Galapagos.
This discovery provides new information and may transform what has been recorded so far in terms of geological processes. According to what has been discovered, hot spots are not fixed in one place. This is how volcanic islands like the Galapagos or Hawaii were formed.
The results confirmed suspicions that geologists had already had
Magma does not rise directly to the surface. Instead, it flows laterally to other points far away. Nevertheless, scientists and geologists already had suspicions about these underground channels. What this study revealed is a confirmation of those suspicions.
Thanks to this research, they now have solid proof. The “chemical signature” found in Costa Rica and Panama is identical to that found in the Galapagos Islands. The course of the magma has also been documented. It flows laterally through an underground passage in the upper parts of our planet.
According to scientists, this underground geological passage was formed about 8 million years ago in the Panama Plate. In any case, scientists confirm that further research is needed. More data will be needed to learn other facts. Like how far the discovered “passage” can extend or if it has other ramifications.
