\"\"Els dies 18 de desembre de 2024 i 9 de gener de 2025, l\u2019alumnat de 1r d\u2019ESO de l\u2019Institut Escola Arts\u00a0<\/a>del barri d’Hostafrancs de Barcelona ha vingut en transport p\u00fablic fins a Pallej\u00e0 per realitzar una sortida de geologia i estudiar diferents afloraments de roques sediment\u00e0ries<\/a><\/span> originades fa m\u00e9s de 200 milions d\u2019anys.<\/p>\n

L\u2019activitat est\u00e0 plantejada com un itinerari i consta de 3 parades en diferents afloraments. En cadascuna d\u2019elles han pres nota de les coordenades UTM, l\u2019altitud i, a partir una s\u00e8rie de proves anal\u00edtiques, han aconseguit identificar les diferents roques que hi han anat trobant, ajudant-se d\u2019una clau dicot\u00f2mica. Han mesurat la pot\u00e8ncia, la granulometria, les estructures sediment\u00e0ries observables en els materials, la seva duresa i, fins i tot, han atacat cada mostra amb HCl dilu\u00eft per detectar-hi la pres\u00e8ncia de carbonat de calci.<\/p>\n

\"\"Amb totes aquestes dades, han concl\u00f2s que el primer aflorament corresponia a un conglomerat i el segon a un gres. Aquestes dues roques rogenques d\u2019origen continental corresponen a ambients sedimentaris al\u00b7luvials del Tri\u00e0sic inferior. En canvi, en l\u2019aflorament superior han identificat roques calc\u00e0ries que indiquen unes condicions de sedimentaci\u00f3 marines. D\u2019aquesta manera han pogut confirmar la transgressi\u00f3 marina que hi va tenir lloc en aquella \u00e8poca i reconstruir la hist\u00f2ria geol\u00f2gica de la zona a partir del principi de superposici\u00f3 dels estrats.<\/p>\n

Han completat una gran feina de camp i han gaudit d\u2019una manera diferent de la geologia. Fins la propera!<\/p>\n","protected":false},"excerpt":{"rendered":"
