Geology

The rock at this site is slag, a material consisting of magma fragments, full of holes and irregular shapes. The lava was thrown out violently by the volcano, formed clouds of molten rock grains. When falling down the volcanic ash forms a special rock which contains a lott of small bubbles. The rock here is a trachytic ash sander named Pouzzolane (pozzolan) after the village Pozzuoli, near Naples, Italy.


Description

The Volcan de Lemptégy is a huge quarry, where the volcanic rocks were mined since the end of World War II. The hard rock is important for many purposes, like building houses, gravel for roads, and more. A 90 minutes long guided tour through the quarry offers geologic background, shows volcanic bombs and the daily work of the quarry workers. There is also an exhibition called La Mine Explosive (Mine Explosive), which seems to be some sort of roller coaster ride.
