Description
The Bierghes quarry is located in the province of Brabant Wallon, 20 km east of Lessines and 30 km west of Brussels.
The rock quarried at Bierghes is a plutonic magmatic rock, from which superb quartz with a variety of facies has been extracted. In contrast to the rather young alpine quartz, these crystals are over 300 million years old. The sample presented here is a good illustration of this rare Belgian mineralogy.
