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 ▲]

The Red Marble of Baelen is a local ornamental stone from the Limbourg area (Vesdre valley, Eastern Belgium), where it has been quarried at least since the 16th century, possibly even from the 9th century. It represents a local Member of the Middle Famennian (late Upper Devonian) Souverain-Pré Formation. It is the only known or at least the only well-documented Mid Famennian red-stained carbonate mudmound complex worldwide. Carbonate microfacies comprise nodular to lenticular algospongal pack/bindstones and massive stromatactis-bearing microbialitic mudstones, both enclosing lenticular crinoidal grain- to rudstones. Silty nodular bioclastic wacke/packstones, strongly affected by pressure solution, mark the transition with underlying and overlying micaceous sandstones and occur as interbeds within the mudmound core. The Red Marble of Baelen displays a few varieties that have been used for a large spectrum of building and decorative purposes, mostly within a short radius of the production sites, in the former Duchy of Limbourg. Its usage was rural and vernacular, although it has been exceptionally employed in prestigious buildings such as the Antwerp town hall. [less ▲]

Several initiatives intended to highlight the geological heritage have been recently developed in the Liège province (Belgium). The Ampsin and Tchafornis (Engis) geosites rank among them. The Ampsin geosite shows the clear-cut passage between the shallow carbonate facies of the Middle Viséan and the terrigenous detrital facies of the Namurian. The Tchafornis geosite gives the opportunity to observe a superb example of biostrome with large colonial rugose corals of the base of the Upper Frasnian (Upper Devonian). Both are located in disused quarries and also give prominence to the regional extractive industry. [less ▲]
