“…Korea 재를 배태한 유망 지역은 발견하기가 어렵다. 이러한 관점에서 좀 더 좋은 집중된 석재의 탐사 방법이 요 구된다 (Selonen et al, 2000). 석재의 탐사에 있어 체계적인 지질학적 조사나 노 하우는 매우 빈약하며 과학적인 방법에 기초를 둔 탐 사방법은 거의 개발되지 않았다.…”

: This research are systematic and scientific approaches to obtain the distribution, occurrence and quality of granite stone for building purposes. The process of dimension stone exploration must be carried out to know the underground potentiality of granitic body using the basic data collection and study, field mapping, detailed drilling survey, televiewer technique, and physical and chemical tests in the Geochang area. Televiewer data obtained in drilling boreholes can be accurately distinguished from the discontinuous face, strike and inclination, extension which is difficult to obtain in a core logging. 3D joint images will be helpful to establish a quarry exploitation plan because the 3D joint images give quite accurate information down to depth below the outcrop surface. Through the process of the quality estimation on the Geochang site, the proven reserve estimated as dimensional building stone are calculated with good quality in petrologic and physical properties.

“…Each of these conditions decreases the quarry's total reserve volume and thus its useful life and production value (Zaruba and Mencl, 1976;Selonen et al, 2000). However, lower-quality phases of the granite, relicts of a gneiss mantle that occasionally covers the granite, reserve losses due to faults, and zones affected by hydrothermal injection or related alterations can compromise quarry operations.…”

In Istanbul, about 50 rock quarries have been opened for the production of specification quality concrete aggregates. Formations exploited include Ç atalca granite, Kü çü kköy sandstone, and Cebeciköy, Hereke, and Kırklareli limestones. In this study, engineering geology parameters affecting the quality of aggregate production and the operational characteristics of rock quarries in these rock types are investigated.Faults, schists that are intruded cut by granites, and microgranites that formed by segregation at the edges of granite intrusions have a negative effect on aggregate quality and operations at quarries in Ç atalca granite. Dikes, faults, folding, weathering, and lithologic transitions in Kü çü kköy sandstone and Cebeciköy limestone have a significant effect on the quality and operational characteristics of those quarries. In Hereke limestone, differential weathering, dolomitization, karstification, and tectonic contacts create similar problems. Lateral and vertical lithological changes, overburden units, karstic openings, and clay-filled fractures cause geologic problems for operations in the Kırklareli formation. Overall, these lithologic and operational problems account for approximate productive reserve losses in these quarries of 15-30 percent for Ç atalca granites, 12-70 percent for Kü çü kköy sandstone, 5-20 percent for Cebeciköy limestone, 5-30 percent for Hereke limestone, and 5-50 percent for Kırklareli limestone. More carefully planned quarrying of these rock types can substantially reduce these losses for more productive operations and the production of construction aggregates of consistently higher quality.

“…Geologists, on the other hand, have shown little interest in exploration for natural stone, and there is not much literature on geological constraints on occurrence or quality of natural stone deposits (cf. Heldal & Lund, 2000;Selonen et al, 2000;Carvalho et al, 2008;Heldal et al, 2008).…”

Regional and local geological constraints for location of natural stone deposits in glaciated terrains of southern and central Finland have been studied and applied to practical exploration for natural stone. A list of geological and topographical aspects to be considered in exploration, is presented. Important aspects refer to: 1. Regional geology of the target area. 2. Magmatism (type and structure of intrusion, relative time of pluton emplacement). 3. Metamorphism (grade, mineral composition, parent material). 4. Deformation (lineaments, shear zones, folding, fault zones, fracture zones, shape preferred mineral orientations), and 5. Topography (relative elevation, micro topography). The proposed aspects can be used as geological guidelines in exploration for granitic natural stones.
