Grand Est is an administrative region in north-eastern France, created in 2016 through the merger of Alsace, Champagne-Ardenne, and Lorraine. It covers approximately 57,400 km², making it one of the largest regions in France. Grand Est borders Belgium, Luxembourg, Germany, and Switzerland, as well as the French regions of Hauts-de-France, Île-de-France, Bourgogne–Franche-Comté, and Auvergne-Rhône-Alpes. Major cities include Strasbourg (the regional capital and seat of several European institutions), Reims, Metz, Nancy, and Mulhouse. The region is drained by major river systems including the Rhine, Meuse, Moselle, Marne, and Seine headwaters.

Geologically, Grand Est is one of the most diverse regions in France, spanning several major geological provinces. The eastern part includes the Vosges Mountains, composed mainly of Variscan crystalline basement rocks (granite, gneiss) overlain locally by sedimentary cover, forming a classic uplifted massif. To the east of the Vosges lies the Upper Rhine Graben, a major Cenozoic rift system filled with thick sedimentary sequences and associated with significant tectonic activity. Much of western and central Grand Est lies within the Paris Basin, dominated by gently dipping Mesozoic and Cenozoic sedimentary rocks, including limestones, chalk, marls, sands, and clays. In the north-east, parts of the region extend into the Lorraine Plateau and the margins of the Rhenish Massif, with older Palaeozoic rocks locally exposed.

This complex geological framework has supported a historically important mineral and extractive heritage. Grand Est was one of France’s major mining regions, particularly in Lorraine, where extensive iron ore (minette) deposits were exploited from the 19th century until the late 20th century and played a central role in French and European industrial development. Coal mining was also significant in the Lorraine coal basin. Elsewhere, quarrying of limestone, sandstone, and chalk has been widespread and remains important for building stone, cement, and aggregates. The Vosges supplied granites and sandstones used in architecture, while potash (sylvite and halite) mining in southern Alsace was historically of major economic importance. Metallic mining has largely ceased, but industrial minerals remain significant.

Administratively, Grand Est is divided into ten departments: Ardennes, Aube, Bas-Rhin, Haut-Rhin, Haute-Marne, Marne, Meurthe-et-Moselle, Meuse, Moselle, and Vosges. The region has a strong and layered cultural identity, reflecting its history at the crossroads of Latin and Germanic Europe, with distinct linguistic and historical traditions in Alsace and Lorraine. Grand Est’s landscapes, settlement patterns, and industrial history are closely tied to its geology, making it a key region for understanding the interaction between tectonics, sedimentary basins, and mineral resources in north-western Europe.
