MARCOS MORO <\/a>GIJ\u00d3N. Lunes, 5 julio 2021, 00:49 <\/a><\/a><\/a><\/a><\/p>\n\n\n\n

Un estudio geol\u00f3gico elaborado por investigadores asturianos de la Universidad de Oviedo<\/strong> y una empresa de M\u00e1laga ha arrojado nueva luz sobre los or\u00edgenes y antig\u00fcedad de la playa de San Lorenzo<\/strong>. Los resultados del trabajo, que lleva por t\u00edtulo ‘Geometr\u00eda de los dep\u00f3sitos litorales en el \u00e1mbito urbano y la bah\u00eda de Gij\u00f3n’ se dar\u00e1n a conocer hoy en el marco del X Congreso Geol\u00f3gico de Espa\u00f1a, que se celebra hasta el mi\u00e9rcoles en Vitoria-Gasteiz.<\/p>\n\n\n\n

La principal revelaci\u00f3n del trabajo es que la dataci\u00f3n m\u00e1s antigua de la principal playa gijonesa est\u00e1 cercana a los 7.000 a\u00f1os (6.900 para ser exactos), dentro del periodo geol\u00f3gico conocido como Holoceno. Una \u00e9poca en la que todav\u00eda hab\u00eda mamuts caminando sobre la Tierra y que coincide tambi\u00e9n con la presencia de las \u00faltimas civilizaciones neol\u00edticas, la aparici\u00f3n de la agricultura y la invenci\u00f3n de la rueda.<\/p>\n\n\n\n

La edad del arenal gijon\u00e9s y de sus sedimentos se ha obtenido a trav\u00e9s de la dataci\u00f3n por termoluminiscencia a partir de los granos de cuarzo. Un m\u00e9todo que se basa en las alteraciones que provocan las radiaciones ionizantes en las estructuras cristalinas de los minerales.<\/p>\n\n\n\n

Con este estudio tambi\u00e9n se ha conseguido afinar mejor los distintos contactos en superficie y profundidad de los distintos dep\u00f3sitos litorales, el sustrato rocoso con su capa de alteraci\u00f3n superficial y el l\u00edmite en profundidad hasta donde alcanzan los dep\u00f3sitos antr\u00f3picos (rellenos en los que ha intervenido la acci\u00f3n humana). Todo ello bajo la ciudad construida que ha llegado a nuestros d\u00edas.Adem\u00e1s de ha realizado una modelizaci\u00f3n en 3D y se ha descubierto que los mayores ……..<\/p>\n\n\n\n
