Descubren 400 "puertas" misteriosas en un campo de volcanes de Arabia Saudita Estiman que tendrían 7 mil años de antigüedad y desconocen cuáles fueron las razones de su construcción miércoles 18 de octubre de 2017 15:04
Los petroglifos más famosos del mundo se encuentran en Nazca, Perú. Creaciones como el Colibrí o el Extraterrestre son imágenes icónicas y reconocibles para los amantes de los viajes y, principalmente, de los misterios, aunque los investigadores pudieron develar cómo y para qué el pueblo que habitó en el Perú talló estos dibujos en la piedra.
Los arqueólogos e historiadores tendrán ahora un nuevo desafío, ya que se acaban de descubrir, gracias a imágenes satelitales, casi 400 misteriosas estructuras en la región de Harrat Khaybar, Arabia Saudita.
Los investigadores las denominaron "puertas" debido a sus formas que simulan una entrada y descansan, en general, sobre las laderas de una cúpula volcánica que alguna vez arrojó lava basáltica. La más pequeña de estas formaciones se extiende por 13 metros, mientras que la más larga llega a los 518 metros de largo.
Detuvieron en Córdoba al violador más buscado del país
Hasta ahora, los científicos pudieron diferenciar dos tipos de "puertas": las que poseen múltiples paredes de piedra que forman un diseño rectangular, y las llamadas puertas de tipo "I", que solo poseen un muro de piedra con montones de piedras en cada extremo.
También develaron que hallaron otros tipos de estructuras de piedra, como las "cometas", que se utilizaron para cazar animales y las "ruedas", todas denominadas por su forma.
Las puertas "están construidas en piedra, las paredes son más o menos escasas", escribió David Kennedy, profesor de la Universidad de Australia Occidental, en un documento que se publicará en la edición de noviembre de la revista Arqueología Arábiga y Epigrafía. Y agregó: "Parecen ser las estructuras artificiales más antiguas del paisaje y no se puede discernir ninguna explicación obvia de su propósito".
"Las puertas se encuentran casi exclusivamente en campos de lava sombríos e inhóspitos con escasa agua o vegetación, lugares aparentemente entre los más inhóspitos para nuestra especie", escribió Kennedy. Sin embargo, los arqueólogos explicaron que hace miles de años el paisaje de la zona era mucho más hospitalario para vivir.
El niño literal: anotó el reto a un compañero en dictado y es furor en las redes
Además, los investigadores aseguraron que las figuras de las "cometas" y las "ruedas" son posteriores, ya que estas estructuras de piedra se construyeron sobre las "puertas". Los restos de flujos de lava también se encuentran a veces en la parte superior de las puertas, lo que indica que estas también son más antiguas que algunos de los flujos, dijo Kennedy.
El vulcanólogo Vic Camp fue uno de los precursores de la investigación. Durante la década de 1980, descubrió -junto a John Roobol- una de las "puertas" en una cúpula de lava y otras estructuras de piedra, en un área del Harrat Khaybar.
Las cúpulas de lava ya no están activas, dijo Camp, y agregó que en el pasado, la lava basáltica cubría algunas de las estructuras de piedra, incluidas las puertas. "Vemos varias áreas donde la lava más joven carece de tales estructuras (de piedra), aunque otras están rodeadas por varias estructuras", comentó Camp a Live Science . De acuerdo al especialista, algunas de las puertas alrededor de la cúpula de lava fueron construidas hace unos 7.000 años. Aunque esto todavía no está confirmado, ya que el trabajo de campo comenzará en los próximos meses.
