Hundreds of smaller and larger areas were studied during the TFM Project, and three sites of particular interest are mentioned here:  The ancient Madonna della Mazza stone Quarry, located on the eastern central side of the mountain massif near the village Pretoro, was extensively studied by the various members of the project, on various scales and applying different type of data acquisition and analyses techniques. The quarry was identified in 1993 by an Eni scouting field trip. In 1995 it was extensively described for the first time and its potential for fracture studies was outlined . After these preliminary notes, the studies of the TaskForceMajella were performed (such as a complete 3D photogrammetrical survey), and the quarry became one of the favorite sites for a visit during many field excursions . For this purpose, the quarry was extensively cleaned and made available for visiting and studying, will all kinds of instruments, as part of the logistics activities of the TFM Project. During these numerous visits, the results of the TaskForceMajella Project were illustrated, and the quarry became well known as the site where deformation bands in carbonate rocks had been discovered and described for the first time . The first results of the fracture studies were published by . Studies on this quarry have continued throughout the following decades (see reference list below). Another extensively studied site (where three-dimensional photogrammetrical surveys were also performed on various scales) regards the ancient Valle Romana bitumen quarry situated in the area of the village Lettomanoppello, where calcarenites partially impregnated with heavy oil testify that the Majella anticline can be regarded as a partially filled oil reservoir. This, still active quarry was identified in 1992 by an Eni field scouting as a potential study site. In 1995 it was extensively described for the first time . Studies that formed part of TaskForceMajella were carried out, following on these preliminary but exhaustive notes (The present owner Italcementi gave their permission, thanks to the extensive logistics efforts performed for the TFM Project). Amongst other, the quarry was covered by a complete topographic and 3D photogrammetrical survey on various scales. For obvious reasons, the quarry became one of the favorite sites visited on many field excursions . The first results of the fracture studies were successively published by and (see also ). Studies on this quarry have continued throughout the following decades (see reference list below). A site of intensive study was the Valle Santo Spirito, situated in the area of the village Fara San Martino.
