<\/a>Els primers contactes de Vidal amb el Montsec<\/h2>\n

Llu\u00eds Mari\u00e0 i Vidal (1842-1921) va ser un enginyer de mines, un excel\u00b7lent investigador de camp i un pioner de la paleontologia. L\u2019any 1872, despr\u00e9s de prospectar la conca amb lignits de l\u2019Alt Bergued\u00e0, va continuar la recerca de carb\u00f3 al Montsec m\u00e9s meridional. Durant dos anys consecutius, 1872 i 1873, va dur a terme dues excursions
des de Santa Maria de Mei\u00e0 i Pont d\u2019\u00c0ger, respectivament, fins als nivells amb carbons propers al poble de R\u00fabies. Durant aquests viatges Vidal fixa la posici\u00f3 i extensi\u00f3 de les capes de carb\u00f3 del Montsec de Mei\u00e0.<\/p>\n<\/div>\n\n \n\n

En aquestes primeres visites Vidal ja localitza diversos f\u00f2ssils aptians, per\u00f2 \u00e9s a partir de 1888, quan \u00e9s nomenat cap del districte miner de Lleida quan torna a explorar el mass\u00eds. A m\u00e9s de dur a terme recerques geol\u00f2giques i paleontol\u00f2giques, tamb\u00e9 s\u2019interessa per les restes arqueol\u00f2giques, donant a con\u00e8ixer diversos d\u00f2lmens.
Gaireb\u00e9 cada any, des de 1888 fins a 1895 fa alguna visita al Montsec, travessant el mass\u00eds de nord a sud i d\u2019est a oest, estudiant la geologia en detall, recol\u00b7lectant f\u00f2ssils i fent fotografies de la zona.<\/p>\n

Les demarcacions mineres 1898<\/a><\/h2>\n

Una de les tasques de Vidal com a cap de la prefectura minera va ser la de delimitar les concessions mineres de carb\u00f3 i pedra litogr\u00e0fica sobre el terreny, de manera que va aprofitar aquestes tasques per continuar amb les seves observacions geol\u00f2giques. La primera indicaci\u00f3 de calc\u00e0ries litogr\u00e0fiques la fa durant una excursi\u00f3 de revisi\u00f3 de l\u2019estratigrafia el 17 d\u2019octubre de 1898, entre l’ermita de Sant Sebasti\u00e0 i el primer cingle, i que possiblement corresponguin a les de la Cabroa (veure Aragon\u00e9s 2019), tot i que en aquell moment ja estava constru\u00efda la carretera que portava a la pedrera de R\u00fabies i que aquesta ja es trobava activa, segons es veu en la fotografia d\u2019octubre de 1899 on es veuen els derrubis de l\u2019explotaci\u00f3. Cal remarcar que per aquelles dates (1898) no s\u2019havia localitzat cap f\u00f2ssil a la pedrera.<\/p>\n<\/div>\n\n \n\n
