Het Rode Marmer van Baelen is een crinoïdenrijke kalksteen uit het jongste Devoon (Boven-Famenniaan) van België, die dagzoomt niet al te ver onder de grens van Nederlands Zuid-Limburg. Deze bouwsteen is geologisch uniek omdat het gesteente waaruit hij werd gewonnen allicht wereldwijd het best gedocumenteerde (en misschien het enige) voorbeeld is van een z.g. bioherm of kalkslibheuvel (“mud mound”) tijdens het Famenniaan. Het calciumcarbonaat in dergelijke kalkslibheuvels is grotendeels van microbiële oorsprong, evenals het ijzerrijke pigment (hematiet) dat de vaak opvallende roze en rode kleuren veroorzaakt.

The Red Marble of Baelen from the Limbourg area (Vesdre Basin, Eastern Belgium) represents a member of the middle Famennian (late Upper Devonian) Souverain-Pré Formation (Late marginifera conodont Zone). It corresponds to a short-term transgressive event and eustatic rise during the Famennian, interrupting the regressive megasequence on the Condroz shelf in Belgium. It is the only known or at least the only well-documented mid-Famennian carbonate mud mound complex worldwide, after the end-Frasnian mass extinction that wiped out numerous invertebrate taxa.

The Becco locality (Liège province), belongs to the Theux tectonic window and represents a proximal, probably fluvial, environment corresponding to a channel infill. We present here a preliminary report of the fossil assemblage discovered at the locality. The Becco site has yielded a diverse flora of early seed plants including Moresnetia zalesskyi, Dorinnotheca streeli and Condrusia sp. This assemblage, characteristic of the Belgian Famennian, highlights the diversity of early spermatophytes in the country. Becco has also delivered a rich vertebrate fauna with antiarch, groenlandaspid and phyllolepid placoderms, diplacanthiform acanthodians, as well as actinopterygians and various sarcopterygians. The fossiliferous assemblage of Becco resembles those of several Devonian tetrapod- bearing localities, including that of Strud in Belgium, and could therefore provide a favorable palaeoecological setting in the search for early tetrapods.

Pissart (2010) published a synthetic map locating high "viviers" (fishponds) areas in the Ardennes (Belgium), some of which were identified in the 1950s' on aerial photographs taken by aircraft flying at low altitude; others have been found on Google Earth in the 2000s'. However, be aware that one and the other source is usable for this purpose only in open landscapes. In 2015, the Public Service of Wallonia, via his site "WalOnMap" launches the Lidar mapping. Among other possibilities, this tool allows only restore the relief of the ground (digital field model), regardless of the plant cover (MNT 2013-2014 "Hillshade") . So the question is to estimate what can be the contribution of this new tool in the identification of traces of lithalsas. [less ▲]

In the surroundings of the hamlet of Becco (Theux, province of Liège , Belgium), the sites of "La Heid de Fer" and 'L'Ourlaine" are known to have supplied lithic materials assigned to the Early Mesolithic (pre-Boreal). Located a the top a small cliff formed by sandstones and siltstones belonging to the Esneux Formation (Devonian, Famennian), "La Heid de Fer" station overlooks a steep slope developed in the shales and siltstones belonging to Lambermont and Hodimont Formations (Upper Devonian, Famennian), within which occurs an oolitic hematite level reaching several decimeters thick (0.5 m maximum). As suggested by the particular topography of these two sites, further investigations should be conducted in this area in search of other traces of the microlithic industry. [less ▲]

L'excursion se place entièrement dans le bord nord du Synclinorium de Dinant tel qu'il est exposé le long de la vallée du Hoyoux, un affluent de la Meuse à Huy (Belgique) situé sur sa rive droite. Elle offre l'opportunité de se familiariser avec la puissante succession sédimentaire dévono-carbonifère (Lochkovien-Namurien). Les dépôts de tufs calcaires de rivière, fossiles et en formation ("travertins" du Hoyoux) sont aussi concernés. Une attention particulière est portée sur la sédimentologie, la tectonique, la géomorphologie et l'utilisation des matériaux dans le patrimoine bâti. [less ▲]

The use of natural resources is a major source of information to study the socio-economic organization of the population from Prehistory to Antiquity, due to the fact that their exchange networks and behaviors changed together with their lifestyles and know-how. If flint or other materials such as shale have been extensively studied, haematite, and particularly the oolitic haematite, remains hardly investigated as a material in terms of its origin and technical methods of utilization. The mesolithic sites of "L'Ourlaine" and the "Heid de Fer" (Becco, Theux, southern Belgium) are very close to an important Famennian (Upper Devonian) oolitic haematite outcrop. [less ▲]
