“…Many studies have been addressing the quarry rehabilitation issue investigating its optimal ultimate strategies and methodologies (Toy and Hadley 1987). These studies considered specific aspects related to the environment and landscape elements (Cocozza Talia and others 2004), sustainability and possibility of reusing such areas for agricultural purposes (Scarascia Mugnozza and Vurro 1991), by making reference to the urban allocation of the concerned areas (Milgrom 2008) or their topographic (Toy and Black 2000;Toy and Chuse 2005) and morphologic (Nicolau 2003;Brenner 1985;Environment Australia 1998) reconstruction, as well as geomorphologic criteria and processes (morphology, morphodynamic, morphoevolution) (Greco and others 2006;Koca and Kincal 2004).…”

This paper addresses quarries rehabilitation issue within a Metropolitan Area. Areas where mining activity is carried out have been subjected to physical and environmental degradation linked both to pursue the building materials extraction and to the city expansion continuously asking for new areas to be developed with residential and service functions. These changes also occurred where environmental and landscape values are present. It has been therefore pointed out the issue of such areas redevelopment that, to be functionally reintegrated, must be consistently linked to the activities and the territorial local contexts characteristics. In this paper the quarries reuse issue is carried out through parameters identification able to define the quarries relationship with the neighboring towns and with their surroundings besides to identify their physical, environmental and landscaping characteristics. Quarry reuse alternatives have been identified among those consistent with the rehabilitation goals, as defined by the planning sector and internationally approved, while their selection is derived from the application of a two-step methodology: a multi-criteria analysis related to punctual parameters at a "site-specific" level, followed by a further territorial indicators checking over the wide area. This application has led to socially accepted results identifying the examined quarries for reuses ranging from agricultural-forestry and urban to functional or naturalistic. The proposed method has also proved to be suitable to address the abandoned quarries reuse problem with a systemic and consultative approach, as it is able to correlate the many variables present in the social and spatial complexity of the Metropolitan Areas.

“…Even in the city centre, some abandoned quarries, albeit small, can be found. The quarries initially located near the centre of Valdemorillo are now within the city centre because of urbanisation due to the rapid increase in population, as reported for some other case studies (Koca and Kıncal, 2004). Different extraction methods can be observed, from direct working, cutting and carving of spheroidal weathered granitic blocks or boulders, to small exploitations, in some of which the upper level is only 20-25 cm thick, used to obtain small ashlars to supply local building stone (Fig.…”

The Church of the Assumption of Our Lady, in Valdemorillo (Madrid, Spain) is almost entirely built with granitoids. The studies and analyses were focused on the oldest part of the building (Ghosts Corner), which will be restored and rehabilitated in the near future. Homogeneous monzogranite is the predominant granitoid used in the Ghosts Corner, followed by granitic porphyry, porphyrytic monzogranite, gneiss and leucogranite. The original quarries that supplied homogeneous monzogranites for the first construction stages correspond to blocks present in the monument's surroundings. Quarries that supplied the granitic porphyries correspond to the dykes located to east-southeast of Valdemorillo, which are oriented N-S in relation to their intrusion direction. The combined use of ultrasonic velocity and Schmidt hammer techniques allowed, first, selection of the most representative blocks and ashlars for sampling. This reduced sampling to a minimum, but yielded representative results for the whole building. Second, the combined values were used to compare results for the building stones of the church to rocks from the surrounding quarries. Stones from the building showed lower ultrasonic and Schmidt hammer values, and higher porosity and water saturation values compared to the original quarry rocks. The anisotropy indices are directly related to the decay processes in the stone: spalling of homogeneous monzogranite and grain disintegration in granitic porphyries. Finally, the methods applied are inexpensive, easy to use and non-destructive techniques, very advisable properties when working with built heritage.

“…The area is constituted mainly by the Late Cretaceous-Paleocene Bornova Flysch Formation that consists of sandstone/shale intercalations developed in a flysch facies (Tarcan & Koca, 2001;Koca & Kıncal, 2004;. Where the sandstones outcrop, the slopes are steep; the shale outcrops are less inclined (10-20°).…”

“…The benches make up the overall slope in shales because there is commonly no stability problem for the following reasons: (1) the slope height of the benches is less than 4 m, and (2) the geometrical condi- Table 6. Bearing-capacity values (analyses according to Serrano & Olalla, 1994 Excavations with height differences of > 5m in shales that formed benches with steep slopes (α > 60°) have, however, created some stability problems because of their deterioration when exposed to air in excavations (Koca & Kıncal, 2004). One of the most important factors affecting the slope stability of the shales was exposure to alternating wetting/drying conditions of the material.…”

The Metropolitan Municipality of Izmir (Turkey) designated a steeply inclined area for the construction of buildings to house the participants of the Izmir University Olympic Games. Before the construction activities could start, engineering geological and geotechnical investigations had to be carried out in order to establish which zones in the area were suitable for safe constructions. Seismic studies, borings and laboratory tests yielded the data, which were used for preparing five hazard maps in a GIS environment. The construction activities based on the results of this complex investigation appeared successful. The engineering geological investigations included geotechnical measurements on core samples obtained from the boreholes (core drilling) and laboratory testing. The rock-quality designation (RQD%) values of the rock units were determined and used in the rock-mass classification (rock-mass rating method) as an input parameter and in the calculation of the bearing capacity of the various rock units. Geophysical surveys were carried out to determine the seismic velocity of the rocks at the site. A short overview is provided of the main problems that had to be dealt with, and of the successive steps taken to solve the engineering-geological problems. Determination of these problems is necessary for adequate land-use planning and construction activities.
