Mining in France is based solely on the nature of the material, whether extracted from the surface or underground. These include fuels (coal, hydrocarbons, gas), metals (iron, copper) and a few other minerals (salt, sulfur). The inventory of mining resources is relatively well known for surface and subsurface deposits.
The Paris area was a relatively flat sea-bottom during the early Cretaceous period: first in a deep-sea environment, then under a more agitated near-shoreline sea towards the end of the same period, Paris's largely silica-based sedimentary deposits became, under the action of pressure and the carbonic acid content of seawater, a thick deposit ...
The Nord-Pas-de-Calais Mining Basin is a mining basin in Northern France that stretches across the Nord and Pas-de-Calais departments. The region is famous for its long history of coal extraction and its testimony to a significant period in the history of industrialisation in Europe, and as a result it was inscribed on the UNESCO World Heritage List in 2012.

Sulfur deposits on a steam vent at Seltún Hot Springs. The hot springs area contains solfataras, bubbling mud pools, fumaroles, hot springs and warm springs. The high sulphur content of the springs give them a characteristic yellow-orange color. Sulfur was mined at this location until the 1880s.
Geologic map of France. Divisions in French Regional Geology. The regional geology of France is commonly divided into the Paris Basin, the Armorican Massif, the Massif Central, the Aquitaine Basin, the Pyrenees, the Alps, the Côte languedocienne, the Sillon rhodanien, the Massif des Vosges, the Massif Ardennais, the Alsace graben (Rhine graben) and Flanders Basin.
The Union Sulphur Company was incorporated in 1896 to utilize the process. However, the high cost of fuel needed to heat the water made the process uneconomic until the 1901 discovery of the Spindletop oil field in Texas provided cheap fuel oil to the region. [6] The Frasch process began economic production at Sulphur Mines, Louisiana in 1903. [3]

Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and produced by volcanic-associated hydrothermal events in submarine environments. [2] [3] [4] These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits
