General Description of the Quarry
In the outcrop under consideration, the Vidraço de Ataíja Creme limestone occurs associated with the Vidraço de Ataíja Azul. The beds have N 30º E, 15º NW attitude, sometimes are thick, somewhat karstified and fractured; however, the extraction of medium size blocks is possible. 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 quarry are quite good and accessibility is fair.
