The center of La Chapelle-Montmoreau can be reached via two municipal roads, which branch off from the D 675 (Nontron - Brantôme) in a westward direction. Both Saint-Front-sur-Nizonne and the D 84 from Nontron to Ribérac can be reached via a municipal road leaving the town center in a north-westerly direction . A municipal road running along the right side of the Boulous valley enables the connection to the D 939 Périgueux - Angoulême expressway via Saint-Crépin-de-Richemont .

Hydrography

The municipal area is traversed in the middle by the Boulou , which drains to the southwest. On the south-western border, it takes up a left branch that pulls down from the Pradarians and marks the municipal boundary with Brantôme en Périgord (formerly Saint-Crépin-de-Richemont). On the left side of the Boulou also receives two dry valleys , the northern ends just below the now dilapidated mill Moulin de Bernillou and the further south located, only very short, just north of the Domaine de Montmoreau . A dry valley also runs on the right side of the valley; it also marks the border with Brantôme en Périgord (formerly Saint-Crépin de Richemont).

geology

The municipality of La Chapelle-Montmoreau is completely underlain by flat-lying ( angle of incidence up to a maximum of 8 ° to the southwest) sediments of the northeast Aquitaine basin . Structurally, the shift structure belongs to the north wing of the Combiers-Saint-Crépin-de-Richemont-Synklinale . The oldest open formation is the Angoulême Formation of the Lower Angoumiens ( Turonium - Formation c 3b ). It is here to massive Rudistenkalke , the layer ribs and smaller cliffs with off-road rock shelters and caves can form. You are open-minded on both sides of the Boulous. Above that follows Upper Angoumien (formation c 3c ) - somewhat more finely banked, cryptocrystalline rudist limestone, which also occur detritic. The relatively hard fossil limestone of the Coniacium (formation c 4 ) lies over the Turon , standing on the southwest border along the two side valleys of the Boulous. At Sainte Marie des Bois there is also a small deposit of Untersanton (Formation 5 a ) - chalky, platy limestone containing glauconite .

Alterites ( colluvium of the formations AC and ACF - sands and gravel ) of the Tertiary lie discordant over the layers of the Upper Cretaceous . You can find them on the two high altitudes northwest and southeast of the Bouloutal. These shell sediments, which were rearranged in the Pleistocene, are crowned by two fossil river systems , the gravel of which is formed in places as solidified conglomerates (formation HF ). Their age is classified as Eocene or Lower Oligocene . The continental sediments come from the Massif Central near Nontron and were poured towards the southwest. They are found along the north-western border at Filoine and along the south-eastern border at Le Claud (municipality of Saint-Pancrace). The high altitudes along the D 675 in the east crown Pliocene to Old Pleistocene gravel in a sandy-clay matrix (formation Fs ).

The dry valleys are filled with ice-age limestone debris (formation GP ). Very recent alluvial sediments of the Holocene have been deposited in the Bouloutal (Formation K ).
