Toute l'ère secondaire est marquée d'une alternance de phases continentales et d'importantes invasions marines, progressant dans des directions très variables. Le Tertiaire va connaître aussi une alternance de transgressions et de régressions; mais, à la différence de ce qui s'était passé au Secondaire, les invasions marines viendront toutes du secteur nord de notre pays: c'est la préfiguration de l'actuelle Mer du Nord. C'est donc un trait fondamental du relief de la Belgique qui s'instaure au Tertiaire. Au Quaternaire, les avancées marines ont été beaucoup plus restreintes et limitées à la plaine du nord du pays.

Remouchamps Cave is located in Frasnian limestones. These limestones are pure, sometimes dolomitic, and in thick beds. The cave displays two levels. The lower one (underground river) is at the level of the main outside river. The upper one, 10 m. higher, is dry. It is also an ancient river bed, but it includes large halls. These halls display huge collapses. [less ▲]

Sedimentological study: Grain size analyses, morphoscopy, morphometry, heavy minerals. Sediments include: fluvial deposits, aeolian deposits, gelifracts. Some very flat pebbles got through a deep sump. A stalagmitic floor covered the fluvial sediments. Aeolian deposits, reworked by rainwash, are restricted to the entrance zone. Gelifraction occured in the same zone. [less ▲]

The geological map of the cavern of Remouchamps was surveyed at a scale of I : 500. The main structural features are two anticlines, with faulted hinges, separated by a syncline. The observed faults are reversed, except for the most northerly - the Faille Cathédrale Nord - which is normal. The strike of the principal faults is about N.- 70-80°E. No faults with this strike have been recognized on the surface at Remouchamps. [less ▲]

The solution coefficient of CO2 in water increases three times when temperature decreases from 35 to 0°C. It was deduced from this, by some researchers, that cold waters are richer in CO2 than warm waters, and thus more aggressive towards limestone. Indeed, CO2 content of water is, according to Henry's law, the product of the solution coefficient by the partial pressure of CO2 in air. This partial pressure varies much more than solution coefficient, and often in the opposite direction. [less ▲]

It is in a cave of the Silesian Upland and in four caves of the Polish Tatra Mts that some fourty analyses of CO2 in air were carried out between the 7 and the 12.4.67. CO2 content is generally very low in the studied caves, sometimes lower than in open air. The lowest figures seem related with low temperatures. [less ▲]

From some measurements of pH and hardness in melt-waters of the Marmolada Glacier (Dolomites), it appears that these waters are - or at least were in September 1965 - strongly alkaline and not very aggressive towards their limestone bedrock; pH on the glacier and just nearby are between 8.8 and 7.8. Calculated CO2 pressure is lower in the glacier (3.6 10 -4 atm) than in anyone of four other samples analysed in the region. [less ▲]

Les carrières de Chambralles, ouvertes dans les bancs de grès verticaux du Famennien supérieur, montrent une grande variété de structures péné-contemporaines de la sédimentation. On y note en particulier, sur un banc largement dégagé, des îlots souvent limités par des micro-falaises et de petites masses de grès isolées, de forme arrondie ("pains de grès"). [less ▲]
