Dijous 9 de maig els alumnes de 1r de batxillerat de l\u2019optativa de CTMA de l\u2019Institut Mart\u00ed i Dot <\/strong>de Sant Feliu de Llobregat han realitzat una sortida de geologia a Pallej\u00e0, per estudiar diferents afloraments de \u00a0roques sedimentaries del Tri\u00e0sic.<\/p>\n

\"\"<\/a>S\u2019han dividit en grups i amb el material de camp necessari han comen\u00e7at l\u2019itinerari. L\u2019activitat consta de 3 parades en els diferents afloraments, on s\u2019han de realitzar una s\u00e8rie de proves (observaci\u00f3 d\u2019estructures sediment\u00e0ries, la granulometria dels materials, comprovar la duresa del mineral que trobem en la roca, reacci\u00f3 amb\u00a0 HCl per confirmar si cont\u00e9 carbonat de calci) per tal d\u2019identificar la roca que estem observant. Tamb\u00e9 han calculat el cabussament dels estrats i la pot\u00e8ncia dels afloraments fent servir diverses t\u00e8cniques matem\u00e0tiques.<\/p>\n

\"\"<\/a>Han comprovat que en el primer aflorament tenim conglomerats i quarcita, en el seg\u00fcent gres i quars amb una petita alternan\u00e7a de argila, tots ells del Buntsandstein i finalment en l\u2019aflorament superior trobem calc\u00e0ries i dolomies del Muschelkalk.<\/p>\n

Amb totes les dades recollides han pogut interpretar l\u2019origen de la seq\u00fc\u00e8ncia, que correspon a una transgressi\u00f3 marina d\u2019una plana al\u00b7luvial i podran elaborar la columna estratigr\u00e0fica corresponent.<\/p>\n

En el cam\u00ed de retorn han inspeccionat un antic forn de cal\u00e7 abandonat.<\/p>\n

Han completat una feina magn\u00edfica aplicant \u00a0t\u00e8cniques de camp relacionades amb la geologia.<\/p>\n","protected":false},"excerpt":{"rendered":"
