Name(s) in local language(s):
Anciennes mines de La Mure (Le Villaret-Susville, Prunières, Saint-Arey)


"South of Grenoble on the N85. On the dumps of the coal mines surrounding this city, one can collect a number of minerals. The principal ones are sphalerite, boulangerite, bournonite, calcite, chalcopyrite, pyrite, tetrahedrite, and siderite." [Belot, 1978]

Former coal mines located under the Senépi mountains (west from La Mure), officially started in 1806 and closed in 1997. These mines have operated six coal layers in Carboniferous (lower Stephanian) sandstones deposited on mica schists and covered by Triassic and Jurassic sediments. All is deformed by the Alpine tectonics in the form of a large syncline (called the La Mure dome) that has complicated the coal operation. Several adits (Le Villaret level 15, Les Merlins level 12, Les Rioux level 12, ...) had cut some mineralized faults (quartz, siderite, and dolomite with miscellaneous sulphides) in mica schists or in Carboniferous/Triassic/Liassic sediments. The vugs in these veins have probably provided the best sulphide specimens in France! These specimens all date from the time of operation because all adits are now closed and the large dumps near the main adits are only composed of finely crushed rubble ...

NB: The coordinates below correspond to the Villaret shaft which was the main shaft of the mining claim, but these mines were very large and many adits were dug in the mountains.

The mine was operated by the "Houilléres du bassin de Dauphiné" group. In 1968 the mine became part of the "Houilléres de bassin du Centre-Midi" group.
