El passat 19 de maig l\u2019alumnat de Ci\u00e8ncies de la Terra de 1r de Batxillerat va fer una sortida per con\u00e8ixer algunes de les formacions geol\u00f2giques m\u00e9s singulars de la nostra comarca amb el guiatge del ge\u00f2leg Albert de Gr\u00e0cia. Es van visitar 5 punts singulars (fotos<\/a>):<\/p>\n

    \n
  1. Mirador del Pla de les forques<\/strong>: Ens ofereix una de les millors vistes de la plana de la fossa tect\u00f2nica de l\u2019Urgellet i del Cad\u00ed.<\/li>\n
  2. Xemeneies de Fades de la Bastida<\/strong>: Aquestes formacions es deuen a que hi ha un seguit de roques de grans dimensions a sobre de sediments fins. Aquestes roques actuen com a paraig\u00fces de les fortes precipitacions que tenen lloc sobretot durant l’estaci\u00f3 estival, fent que les roques toves que es troben a sota d’elles no s’erosionin, sin\u00f3 que hi hagi una erosi\u00f3 al seu voltant arrossegant molts sediments.<\/li>\n
  3. Roques vermelles de la Traba<\/strong>: En aquest entorn, l’antiga serralada herciniana es va erosionant i es produeix una sedimentaci\u00f3 de materials detr\u00edtics, b\u00e0sicament argilosos, transportats pel vent i durant les crescudes dels torrents, i acumulats al peu dels vessants arrasats. Els minerals de ferro pateixen una forta oxidaci\u00f3 que d\u00f3na a tots els materials un caracter\u00edstic color vermell.<\/li>\n
  4. Conglomerats del Coll de l\u2019Endurant<\/strong>: El nivell de conglomerats marca l\u2019inici de l\u2019era Secund\u00e0ria (mesozoic). Les roques d\u2019aquest indret s\u00f3n conglomerats molt resistents, formats per c\u00f2dols de quars molt ben arrodonits. Aquests c\u00f2dols van incidir amb for\u00e7a damunt dels sediments m\u00e9s tous de sota, argiles vermelles, i hi van excavar milers de paleocanals de totes les mides. Amb l\u2019erosi\u00f3 han desaparegut les argiles, que eren la base d\u2019aquests paleocanals. Aix\u00f2 ha deixat al descobert els c\u00f2dols sil\u00edcics que s\u2019havien sedimentat i fossilitzat a sobre, fet que ens mostra el negatiu dels paleocanals.<\/li>\n
  5. Coll de Creus<\/strong>: l\u00edmit natural entre la Vall del Segre i la Vall de la Vansa.<\/li>\n<\/ol>\n
