\"\"Dilluns 9 de maig l\u2019alumnat de1r de batxillerat de l\u2019optativa CTMA de l\u2019Escola IPSE<\/a>\u00a0<\/strong>de Barcelona han vingut fins a Pallej\u00e0 per realitzar una sortida de geologia i estudiar diferents afloraments de roques sedimentaries del Tri\u00e0sic<\/a>.<\/p>\n

L\u2019activitat est\u00e0 plantejada com un itinerari que consta de 3 parades en diferents afloraments. En cada un d\u2019ells i amb el material necessari, han sigut capa\u00e7os d\u2019obtenir les dades topogr\u00e0fiques com les coordenades UTM, l\u2019altitud\u00a0i la pot\u00e8ncia dels afloraments. Aix\u00ed mateix, en cada aflorament han dur a terme una s\u00e8rie de proves com un examen de la granulometria dels materials, la comprovaci\u00f3 de la duresa del mineral predominant en la roca per identificar-la i tamb\u00e9 la prova de reacci\u00f3 amb\u00a0HCl per confirmar la pres\u00e8ncia de carbonat de calci.<\/p>\n

Com a resultat, han confirmat que el primer aflorament correspon a conglomerat amb quarsita i el segon correspon a gres ric en quars. Aquestes dues roques rogenques d\u2019origen continental corresponen a ambients sedimentaris al\u00b7luvials del Tri\u00e0sic inferior. En l\u2019aflorament superior han identificat calc\u00e0ries i dolomies corresponents al segon estatge del Tri\u00e0sic que indiquen unes condicions de sedimentaci\u00f3 marines. D\u2019aquesta manera han pogut confirmar la transgressi\u00f3 marina que va tenir lloc en aquella \u00e8poca.<\/p>\n

Estaven motivats i han sigut molt participatius, enhorabona!
