Tabataud Quarry
The Tabataud Quarry (sometimes also written Tabateaud) was situated in the northwestern French Massif Central. The quarry used to be mined for its granodiorite.
The Tabataud Quarry was excavated along the left bank of the river Bandiat at an elevation of 165 metres, only about one kilometer southeast of Nontron town centre. Nearby passes the D 707 from Nontron to Saint-Pardoux-la-Rivière, from which it is easily accessible. In the immediate vicinity are two more adjoining quarries, the ''Maspeyrot-Lagarde quarry'' and the ''Moulin Blanc quarry'', which are both older. All these quarries are closed by now and they are dangerous due to rockfall.
The quarry is noted for its minerals. The Tabataud quarry most probably yielded the finest galenas in the whole of France. It is furthermore one of the very few sites for wulfenite in France. As a rarity occurs the pseudomineral ozocerite. The cerussite is of extremely good quality and diversity.
== Geology ==
The Tabataud quarry and its two satellites were worked from the Piégut-Pluviers Granodiorite, more precisely from its dark, fine-grained, biotite- and amphibole-bearing (green hornblende) border facies. Because of its slight blueish hue the rock used to be called ''granite bleu'' (blue granite) by the local population. Along the west side of the quarry crosses a NNE-SSW-striking fault zone that sets off the granodiorite from the plagioclase-bearing paragneisses farther west. Within the quarry the granodiorite is traversed by a stockwork of mineralized dikes. Altogether 17 southeast-northwest-striking lodes are encountered. They only reach thicknesses of about 3 centimeters, an exception being the ''Puyssechet lode'' near the ''Moulin Blanc quarry'', which is cm thick and strikes east-west. Besides the lodes there are also some pegmatite dikes.
