General Description of the Quarry
In the outcrop under consideration, the Vidraço de Ataíja Azul limestone occurs associated with the Vidraço de Ataíja Creme, its bluish-grey colour being due to organic matter contents. The beds have N 30º E, 15º NW attitude, sometimes are thick, somewhat karstified and fractured; however, it is possible the extraction of medium size blocks. The main joint systems have average attitudes N 85º W, 85º N, N 10º W, 65º E and N 40º W, 80º E, the later one being less important. In general, slabs are obtained by cutting the blocks according to the rift plane. The reserves in this area are fairly good and the accessibility to the quarry is fair.
