\"\"Divendres 23 de maig 2025, l\u2019alumnat de Geologia i Ci\u00e8ncies Ambientals de 1r de batxillerat de l\u2019Institut Fort Pius <\/a>de Barcelona ha vingut fins a Pallej\u00e0 per estudiar tres afloraments diferents de roques sediment\u00e0ries del Tri\u00e0sic.<\/a><\/p>\n

L’objectiu de la sortida \u00e9s reconstruir tant la hist\u00f2ria geol\u00f2gica d\u2019aquests dip\u00f2sits com els seus ambients sedimentaris. L\u2019activitat est\u00e0 plantejada com un itinerari circular amb 3 parades diferenciades. En cadascuna d\u2019elles han pres nota de les coordenades UTM, de l\u2019altitud i, a partir una s\u00e8rie de proves anal\u00edtiques, han aconseguit identificar les diferents roques que 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 i la duresa dels seus minerals. Fins i tot han atacat cada mostra amb \u00e0cid clorh\u00eddric (HCl) dilu\u00eft al 10% 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, a l\u2019aflorament superior han identificat roques calc\u00e0ries amb alguns f\u00f2ssils que indicaven unes condicions de sedimentaci\u00f3 marines.<\/p>\n

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 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.<\/p>\n

Enhorabona i fins aviat!<\/p>\n","protected":false},"excerpt":{"rendered":"
