The coastal marine area between Cap d'Antifer and Cap d'Ailly was the subject of a geological mapping programme in 2006. The previously unpublished results are presented as six 1:20000 scale maps and an explanatory booklet. The abundantly-illustrated booklet comments on the different geological structures surveyed. The findings should be of interest to professionals, teachers, developers and policymakers.

La carte des sols de Besançon à 1/100 000 occupe une position centrale dans la région de Franche-Comté. Elle est représentative de la distribution des sols développés sur le calcaire jurassique.

La carte des sols de Langon à 1/100 000 couvre 2280 km2 situés en Aquitaine, et pour l'essentiel dans le département de la Gironde et le Bordelais. Cette carte, située au carrefour des sables des landes, de la vallée de la Garonne, des graves, et des pays de collines de l'Entre-Deux-Mers,  présente une diversité remarquable, représentative d'un secteur aquitain bien plus vaste.

Threatened by changing environmental conditions and anthropogenic actions, cold water corals are currently classed as a vulnerable ecosystem by several international institutions. One objective of this study is to characterise their habitats from the geological shapes of the sea bed.

The Bay of Lannion underwent a geological mapping programme between 2005 and 2009. The previously unpublished results are presented as seven 1:20000 scale maps and an explanatory booklet.

The 1:100000 scale soil map of Janzé partly covers 2156 km² in the south-eastern section of the Armorican Massif. The geological diversity of this region to the south of Rennes has seen a soil wealth develop over thousands of years.

An essential component of our environment, the soil is nowadays viewed as a natural heritage. The author describes the spread, properties and functioning of main soils in large physiographic and pedological areas in France along with their pedogenetic evolution. He makes an inventory of different types of sequence and soil-system.
