What appeared like the lost city of Greek on bottom of sea in the year 2013 now has deemed as the phenomenon that is a naturally occurring. It was discovered by the underwater divers that appeared like the paved floors, colonnades and courtyards; they believed they have found ruins of civilization which is long-forgotten and perished when the strong tidal waves smashed the shores of Zakynthos, the Greek island.
But according to the research done by University of East Anglia in UK and University of Athens in Greece, has revealed that this site was developed by the natural phenomenon of geological that happened in Pliocene era for 5 million years before.
The inexplicable discovery, also found near to the Alikanas Bay, was vigilantly observed in situ through Underwater Antiquities of Ephorate in Greece.
Julian Andrews, the Lead author mentioned, “We have thoroughly investigated the site that is mainly between 2-4 meters under the water and it was found that it is basically the natural phenomenon of geological imbalance. The doughnut and disk morphology that looked like the circular bases of column is basically the mineralization at the seeps of hydrocarbon – seen that both in the modern seafloor with the settings of palaeo.” This study happened in Marine geology and Petroleum Geology.
Andrews also noted that linear distribution of concretions that are doughnut shaped is possibly the best result of the fault for sub-surface that has not completely ruptured surface of sea bed. This fault has allowed gases, specifically methane, to get escape from the depth. Microbes of sediment use carbon in the methane like a fuel. However, oxidation that is Microbe-driven of methane will change the entire chemistry of sediment creating the type of natural cement, also known as concretion by geologists.
In such a case, cement was also a rare mineral known for dolomite that rarely creates in the seawater, but may also be common in the sediments that are rich in microbe. Such concretions then got exhumed through erosion to get exposed on seabed, she then added.
She also concluded that such features are a great proof of the natural methane seeping from rock from the hydrocarbon reservoirs. This similar thing happened in North Sea, and is similar to fracking effects, when humans particularly speed up and improve the phenomena.
