Aquest divendres 13 de mar\u00e7 hem fet una trobada de geologia amb l’alumnat de batxillerat dels instituts Frederic Mompou<\/a> de Sant Vi\u00e7ens dels Horts, Fort Pius<\/a> de Barcelona i Joanot Martorell<\/a> d’Esplugues de Llobregat per descobrir tots plegats la seq\u00fc\u00e8ncia sediment\u00e0ria del Tri\u00e0sic a Pallej\u00e0<\/a>.<\/p>\n

I \u00e9s que com a experts i expertes han aconseguit 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 i de l\u2019altitud. Sabeu que al tri\u00e0sic, fa 250 milions d’anys, Pallej\u00e0 estava situat a 8 graus de latitud nord? Consulteu-ho a paleolatitude.org<\/a>! 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,\u00a0la seva duresa i tamb\u00e9 han observat <\/span>les estructures sediment\u00e0ries en els materials. 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.<\/span><\/p>\n

Amb totes aquestes dades han concl\u00f2s que el primer aflorament correspon 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 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 a partir del principi de superposici\u00f3 dels estrats.<\/p>\n\r\n\t
